What Is This 2-Week Abs Workout Challenge and Who Is It For?

This 2-week Abs Workout Challenge is a structured, no-equipment program with 20-40 min/day of focused core work, progressive difficulty, low-impact options, and clear tracking so you finish stronger, tighter, and closer to visible, defined abs without guessing, scrolling, or burning out.

This isn’t a random “killer workout!” thread. It’s a repeatable system. Simple, intense, smart. Built for busy people who want real progress over hype.

You’ll train six days per week for two weeks. Sessions run 20-40 min/day, combining static holds, controlled reps, and short, intense finishers. Every workout hits core, body tension, and breathing.

No-equipment means zero excuses. Floor, timer, done. If you’ve followed darebee style programs or streaming classes, this will feel sharper, tighter, and better structured.

Who This Program Is For

• Beginners needing clear levels, focusing on form and safety.
• Intermediate lifters stuck “almost shredded.”
• Runners wanting stronger cores and fewer foot or back issues: see this guide.
• Busy parents, executives, students who can commit 20 focused minutes.

It fits any schedule. Home, hotel, or office. No jumping is required; every session includes low-impact paths that still feel intense.

You’ll track reps, holds, and repeats so progress isn’t a guess. Use any watch you own or review options here: performance tools for better tracking.

Evidence: controlled, consistent core training for 2+ weeks improves endurance, posture, and trunk strength markers in current sports science data heading into 2025. You commit. This program returns a stronger, clearer sixpack signal over everything soft.

How Does This No-Equipment 14-Day Core Program Work Day by Day?

This 14-day no-equipment Abs Workout Challenge stacks short, intense core workouts in smart waves: foundation, intensity, and peak. You’ll train 20-40 min/day with clear progress tracking, low-impact options, and strategic repeats. Every session pushes you closer to a stronger, defined midsection that actually shows.

Week 1: Foundation and Fire (Days 1-7)

Day 1-2: Basic core, body tension, breathing. Think dead bugs, planks, heel taps. No jumping. Low-impact, joint-safe, 20 minute caps.

Day 3: Longer minute rounds. Add side planks and glute bridges. You’ll feel deeper trunk fatigue without equipment or fluff.

Day 4-5: Progress the same exercises with tougher angles. Longer holds. Shorter rest. This builds capacity fast, backed by 2025 EMG studies on time-under-tension.

Day 6: Controlled “killer” circuit: 8-10 moves, zero breaks. You test form, not ego. Optional wearable tracking keeps your effort honest.

Day 7: Active recovery. Walking, mobility, light streaming follow-along. Zero crunches. Let the core adapt while staying engaged with the program.

Week 2: Intensify and Carve (Days 8-14)

Day 8-10: Harder planks, hollow holds, reverse crunches. Intense, still low-impact. Every set takes you closer to sixpack definition.

Day 11: Repeat your “killer” workout! Track reps, total time, and RPE. Evidence shows simple metrics beat vague guessing for progress.

Day 12-13: Mixed core, body chains, rotation. 20-40 minute structured circuits. No-equipment, no nonsense, darebee-level clarity, all levels focusing on form.

Day 14: Benchmark test: max quality reps, strong holds. Compare over days to see concrete progress tracking. Then stack this into your next 18-day, 20-day, or 6-week workout! For recovery support, see smart protein choices.

How Long Should Each Abs Workout Challenge Session Be (20-40 min/day)?

Each Abs Workout Challenge session should run 20-40 min/day: 5 minutes activation, 10-20 minutes focused core work, 5-10 minutes conditioning or low-impact finishers, and a 3-5 minute cool-down. Long enough to grow defined abs and skill, short enough to repeat for weeks.

Think in minutes, not myths. You’re building a stronger core, not chasing a random “killer sixpack workout!” clip. Research since 2023 shows 12-25 hard working sets per muscle group per week drives growth when paired with sleep and protein.

So across this no-equipment program, 20-40 minutes lets you hit smart volume without frying your body. Short bursts. High intent. Clean technique. Zero junk reps. That’s how you get closer to shredded: not exhausted, but consistent.

Exact 20-40 min/day structure that scales

Use three levels, focusing on efficiency, not ego:

• Beginner: 20-minute low-impact core, no jumping, strict form.
• Intermediate: 30 minutes with controlled intense blocks and repeats.
• Advanced: 35-40 minute minute-based blocks, near-failure, tight rest.

This approach mirrors top free resources like darebee while fixing the big gap: actual progress tracking. Every session stacks, nothing is random.

Data, streaming, and staying honest

Use a watch or app to track time and progress; see this breakdown for accurate minute-by-minute monitoring. Streaming follow-along sessions keep pacing tight and effort high without equipment.

Across 14 days, this 20-40 min/day Abs Workout Challenge structure compounds: sharper form, stronger core, defined lines. Miss minutes, not days. Go hard, then stop.

What Is the Most Effective Ab Workout Ever Within This Program?

The most effective ab workout in this Abs Workout Challenge is a 20-40 min/day, no-equipment, high-tension circuit that attacks your entire core, keeps your heart rate high, and repeats key patterns across two weeks so your body adapts, your waist tightens, and your abs start looking defined.

The Core Of The Program: One Killer Sequence

This program isn’t random. It’s engineered. Short, intense blocks. Smart rest. Max intent.

You’ll hit upper, lower, and deep core, plus stability. That’s how you get closer to a real sixpack, not a pump that fades.

The “Most Effective” Circuit (No Equipment, All Levels)

This sequence runs 18-20 minute straight, low-impact, no jumping, pure control. It fits busy weeks and scales through levels, focusing on positions that force the core, not the hip flexors, to work.

Rest 20 seconds between moves. Rest 60 seconds at the end. Then repeat the circuit 3-4 times. That’s your minute-for-minute most effective workout within this program.

Evidence: Since 2023, EMG studies show controlled anti-extension and anti-rotation drills, like planks and dead bugs, recruit the core more efficiently than high-rep crunches, with lower injury risk. This circuit aligns with that data heading into 2025.

Track progress with visible reps, tighter form, and reduced waist over 14 days: use any watch you love or see options at smart tracking wearables. Treat this as your no-excuses, streaming-ready, darebee-level structured workout!

Does the 30 Days Abs Challenge Work Compared to a 2-Week Plan?

The classic 30 days abs trend works for discipline, not miracles. A focused 2-week Abs Workout Challenge with smart progress, no-equipment exercises, and tight tracking beats random 30-day repeats. Two sharp weeks build tension, proof, and momentum that you can scale all year.

Why 30 Days Isn’t the Magic Number

Most 30-day apps push the same crunch-based program. Volume climbs. Quality dies. People quit.

By week three, fatigue spikes, form breaks, progress stalls. No nutrition link. No intensity strategy. Just noise.

The 2-Week Edge: Intense, Precise, Realistic

A 2-week plan lets you go hard without burning out. Think 20-40 min/day, structured, no-equipment, low-impact options, zero guesswork.

You’re closer to defined abs by pairing intense minute blocks with smart recovery and clean food. Evidence first: visible change often starts within 10-14 days at consistent deficit and progressive core work (2025 ACSM data trend reports).

How to Make Your 2 Weeks Count

Stack intense but safe killer blocks. Planks, hollow holds, leg lowers, anti-rotation. No jumping needed.

Set levels, focusing on strict form and complete ranges. Pull drills from darebee, streaming workouts, or custom sixpack workout! series.

• Daily progress tracking with a smart watch: track every minute.
• Support fat loss with smart protein choices: optimize recovery.

Use those 14 days as your test phase. If it works, repeat the Abs Workout Challenge in 18-day or 4-weeks waves, adjusting loads, not chasing another shallow 30 days trend.

Will 100 Crunches a Day Lose Belly Fat or Build a Sixpack?

No. Doing 100 crunches a day won’t lose belly fat or build a real sixpack by itself. Crunches hit a slice of your core, burn few calories, and ignore diet. You’ll see definition only when body fat drops and your total Abs Workout Challenge trains the whole core with intent.

Here’s the truth for 2025: spot reduction is dead. Large reviews show you can’t target belly fat with one exercise; fat loss comes from total energy deficit, sleep, stress control, and consistent training.

But 100 smart crunches can help if they’re one piece of a no-equipment program. Think 20-40 min/day, mixing positions, speeds, and angles. You’re not chasing burn; you’re building muscle that will show once you’re lean enough.

Why 100 Crunches Alone Fall Short

• Low calorie burn: about 5-8 calories per minute.
• Hits mainly upper abs; ignores deep core and obliques.
• High repeats with bad form stress your neck and spine.

A 2024 meta-analysis on core training found multi-angle, progressive core exercises improve definition faster than endless repeats of one move when combined with modest caloric restriction and high protein intake.

The Better Play: Make Crunches Earn Their Place

Use them inside a focused, low-impact, no-equipment sequence: dead bugs, reverse crunches, planks, side planks, then controlled crunches. Keep it intense, 15-20 minute killer blocks, 5-6 days per week.

Track progress weekly: waist, photos, and strength markers. Use a watch from this guide or a simple habit tracker. Run this for two weeks straight; if your diet’s aligned, you’ll move closer to a defined sixpack that’s built, not guessed.

How Do I Perform Each Core Exercise Safely to Protect My Back?

Perform each core exercise with a neutral spine, braced abs, and zero forced range. If your lower back feels “pinchy,” you’re past your safe zone. Slow each rep, exhale on effort, and stop two reps before form breaks. Safety scales your Abs Workout Challenge, pain ends it.

The 3 Non-Negotiables for Back-Safe Core Work

First: lock your ribs down. Imagine zipping ribs to hips. This keeps your core, not your spine, working.

Second: squeeze your glutes. A light squeeze protects your body when your legs move.

Third: no yanking your neck. Hands guide. Core drives.

Safe Form Cues for Key No-Equipment Exercises

Intensity Without Injury

This 2-week program stays intense without equipment by staying strict. Short minute bursts. Killer control. No ego reps.

Research through 2025 shows controlled tempo and neutral spine cut injury risk while driving defined sixpack strength and better fitness outcomes.

• Use streaming timers or a Garmin-style tracker for progress tracking. Try this guide.
• If pain repeats, regress one step. Smart beats shredded: over.
• Compare to structured no-equipment plans like darebee for structure ideas.

This Abs Workout Challenge moves you closer to strong, defined abs fast. Respect your spine, scale reps, and your body will adapt across the full workout! If you need support tools, start at our essential gear hub.

How Can Beginners, Advanced Athletes, and Low-Impact Levels Adjust This Challenge?

Beginners, advanced athletes, and low-impact levels adjust this Abs Workout Challenge by controlling pace, exercise choices, and total volume: 20-40 min/day, 3 scalable levels, strict form, smart repeats, and clear tracking. Same structure, different intensity. Everyone gets closer to a defined core without equipment or risk.

Level 1: True Beginner / Busy Starter

Keep it simple. Think 10-20 min/day, three rounds max, no jumping.

Use basic no-equipment exercises: dead bugs, dead hangs (if possible), heel taps, planks. Rest as needed. Aim for progress, not pain.

Level 2: Intermediate / Low-Impact Precision

This level suits people who want intense work without impact.

Use slow mountain climbers, controlled leg raises, side planks, hollow holds. Zero jumping, joints safe, core lit. Perfect if you’re protecting knees, or coming back from injury.

Level 3: Advanced Athlete / Sixpack Ambition

You want a killer minute, sixpack workout? Go here.

Stack 20-40 min/day, minimal rest, strict tempo. Add pause holds, extended planks, V-ups, and brutal repeats. This will feel over, then it bites again.

Tracking, Streaming, and Proof

Stream your sessions, log every round, and track progress with a sports watch: try this option or similar.

Research through 2025 confirms consistent programmed core work improves trunk strength and visible definition within weeks when paired with dialed nutrition and total-body fitness.

How Do I Combine This Abs Workout Challenge With Nutrition and Cardio for Defined Abs?

You combine this Abs Workout Challenge with smart food, daily movement, and tight tracking. Eat in a slight deficit, hit enough protein, walk or do low-impact cardio most days, and keep the no-equipment core work intense. That stack burns fat, preserves muscle, and exposes defined abs.

Abs show when body fat drops. Not when you add endless exercises. So we stack three levers: nutrition, cardio, and this program.

1. Simple Nutrition Rules That Work in 2025

Target 0.7–1.0g protein per pound. Every day. Non-negotiable. Evidence through 2024 shows this keeps muscle while cutting.

Run a 300–500 calorie deficit. Track for two weeks. Adjust based on waist and weight progress, not vibes. Use this caloric restriction guide for deeper numbers.

2. Cardio That Supports, Not Kills, Your Core

Do 20-40 min/day of brisk walking, cycling, or low-impact intervals. Five to six days a week. This bumps total burn without trashing recovery.

If your joints handle it, add one short, intense minute-based session weekly. Think 10 rounds: 30 seconds hard, 30 seconds easy. No equipment. Pure intent.

3. Fitting It All With the Challenge

Run the Abs Workout Challenge first or second in your routine. Keep exercises strict. No ego, no lazy repeats. Aim for 7+ weeks closer to that defined, shredded sixpack look across cycles.

Use a watch or app for progress tracking. Try this tracking upgrade to keep everything measured, not guessed.

How Do I Track Progress, Results, and Get Closer to Shredded Abs Over 2 Weeks?

You track progress by numbers, photos, and performance: waist measurements, weekly ab check-ins, total reps, and how long you hold form under fatigue. Over this 2-week Abs Workout Challenge, that data tells you if you’re getting closer to defined, shredded abs or just sweating without progress.

Start with a 3-point check: waist, navel, and hips. Measure on day 1, 7, and 14. Same time, same conditions, no guesswork.

Next, lock in performance tests. Time a forearm plank, count strict dead bugs, hollow holds, or reverse crunches. No jumping, no equipment, just brutal core, body control.

Run 20-40 min/day of focused no-equipment exercises. Keep every minute intentional. Short, intense, low-impact sets beat random scrolling workouts.

Use a simple progress tracker, not a pretty app trap. Here’s the structure.

Take front/side photos under the same light. Research from 2023-2025 body comp trials shows visual tracking boosts adherence and accuracy when scales lie.

If you stream the program, watch each workout! Treat it like a guided, minute-by-minute killer sixpack workout!, not background noise.

Need tech? A basic watch from this guide or tools from Gear Up to Fit helps track time, heart rate, and consistency.

Progress isn’t magic. It’s visible tension, cleaner reps, less rest, and data that proves you suffered on purpose.

Your 2 weeks won’t carve a full shredded: movie-core yet, but this Abs Workout Challenge moves you closer fast if your tracking is honest and your effort stays intense.

How Can I Use Streaming, Follow-Along Videos, and Darebee-Style Workouts in This Program?

You’ll use streaming, follow-along videos, and darebee-style workouts to make this Abs Workout Challenge automatic: hit play, match the pace, follow clear reps and minute cues, stack intensity smartly, and stay consistent for 2 weeks so your core gets stronger, tighter, and closer to defined, visible lines.

How Streaming Supercharges a No-Equipment Program

Pick one follow-along sixpack workout! video for each day. Aim for 20-40 min/day, mixing low-impact and intense blocks with no equipment.

Streaming keeps your pace honest. No scrolling, no guessing. Just structured work and short repeats.

Darebee-Style Structure, 2025-Level Discipline

Use darebee formats: clear levels, simple no-equipment exercises, zero fluff. Think: 3-5 rounds, 30-45 second efforts, 15-second rests.

Every workout’s focusing on core, but we’ll hit full body so you burn more and get shredded: without endless jumping.

Video Summary, Tracking, and Proof

The video walkthrough shows one full 20-minute structure, exact exercises, rest rules, and how the program repeats across weeks so progress isn’t random.

Track your minute volume and holds with any fitness watch you trust (data-focused athletes love this). Studies through 2024 show consistent 8-12 week core work cuts waist size and boosts strength; this 2-week hit is your trigger, not the finish line.

What Are the Red Flags, Safety Tips, and When Should I Stop This Killer Workout?

Stop this Abs Workout Challenge the second pain feels sharp, dizzy, or wrong. Safety beats ego. Respect form, breathing, and control. Your core should feel taxed, not torn. If anything feels unstable, numb, or stabbing, you’re done for that session. That’s how smart athletes win long term.

Non-Negotiable Red Flags

Your abs burn? Good. Your spine hurts? Stop.

Watch for: gripping neck, hip flexor strain, joint pain, or swelling after no-equipment exercises. Research through 2025 shows pushing through sharp pain raises injury risk, delays progress, and kills consistency.

Essential Safety Rules for This Killer Workout

Warm up 3-5 minutes. March, hip circles, gentle twists. Keep it low-impact; no wild jumping on cold joints.

Each 20-40 min/day session: brace your core, neutral spine, smooth breathing. Don’t chase shredded: minute 1. Chase perfect reps over speed.

• Use clear reps, not ego reps.
• Cap volume if form breaks for two sets straight.
• Take 1 rest day per 3-4 intense days.

Track progress daily. Simple log: sets, holds, notes. Use a watch from this guide if you want precise tracking.

When You Must Stop the Program

End or pause the program if pain lasts over 48 hours, fatigue crushes sleep, or basic movements hurt. That’s not grit. That’s damage.

If you’re unsure, scale to beginner levels, focusing on body control and safer core patterns inspired by proven programs like darebee, then rebuild toward that sixpack workout! This is how you get defined results without wrecking your body.

How Do I Maintain Results and Repeat or Extend the Abs Challenge Beyond 18-Day and 30-Day Programs?

You maintain and extend your Abs Workout Challenge results by treating it as your new baseline: stay at 20-40 min/day, rotate intensity and levels, track progress weekly, protect your core with recovery, and cycle 18-day and 30-day no-equipment programs with smarter repeats, not random workouts.

Lock It In: 4-Week Repeat Framework

After an 18-day, 30-day, or darebee-style program, don’t stop. Run a simple 4-week block so your body keeps what it earned.

Train 5 days per week. Mix intense and low-impact days to keep your core, joints, and energy sharp.

Progress Tracking That Forces Results

Visible abs in 2025+ demand hard data. Photos, waist, and strength tests beat feelings.

Use a watch from this list or similar tech for consistent tracking. Research supports objective tracking for higher adherence over time.

• Record plank time and hanging hold, weekly.
• Keep carbs and protein aligned with your goal.
• Run repeats of the program, raising difficulty each cycle.

Every repeat should move you closer: sharper core, lower body fat, cleaner form.

This section’s video should show how to stack 18-day, 30-day, and extended weeks into a sustainable year-round program, using no equipment, streaming follow-alongs, and smart progress tracking.

How Do I Integrate This Abs Workout Challenge With Full-Body Fitness and Minimal Equipment?

You integrate this Abs Workout Challenge by treating it as your non‑negotiable core anchor, then stacking 20-40 min/day simple full-body no-equipment exercises around it: push, pull, hinge, squat, carry patterns, low-impact conditioning, plus smart recovery, so your whole body gets stronger while your waist gets sharper.

Step 1: Set the Weekly Structure

Run the ab program 6 days across two weeks. Keep it tight.

Add three full-body sessions on alternating days. Zero chaos, pure intent.

Step 2: Use Only What You Have

This system stays no-equipment friendly. Bodyweight wins.

Think squats, hip hinges, slow pushups, step-ups, jumping only if joints agree.

Step 3: Track, Progress, Repeat

Research through 2024 shows progress tracking doubles adherence through week six. Source: ACSM and peer-reviewed adherence data.

Use a simple sheet or a basic watch: track sessions and HR trends. Aim tiny weekly increases.

• Shorter rests, same reps.
• Harder angles and slower tempo.
• Extra round of your minute killer finisher.

Pair this structure with smart protein intake and sleep support from evidence-backed nutrition, and your core, body, and fitness move closer to that defined, shredded sixpack workout result without pointless equipment repeats.

Where Can I Find Trustworthy References, Case Studies, and Next Steps After This Intense Challenge?

You find trustworthy references and next steps by following peer-reviewed research, proven no-equipment programs, real-world transformation data, and ongoing progress tracking tools that extend your Abs Workout Challenge beyond two weeks and force you closer to visible, defined results without drifting back to random, low-impact effort.

1. Start With Evidence, Not Hype

Since 2023, multiple RCTs confirm this: 20-40 min/day focused core work, three to five times per week, beats long, random workouts. It improves trunk strength, posture, and injury resilience across all levels.

Use PubMed, Sports Medicine, and NSCA resources. Filter for 2020-2025, “bodyweight core, no-equipment, EMG,” to stress data, not trends.

2. Proven No-Equipment Programs and Case Studies

Darebee-style templates, 18-day, 2-week, and 30-day formats work when you repeat structured intense sessions and track. The best programs are boringly consistent. Same killer patterns. Strategic repeats.

Review case studies from certified coaches and sports scientists who share month-over-month core, body fat, and performance changes. Look for clear programming: minute blocks, rest ratios, and exercise lists.

3. Your Next 30 Days After This Challenge

Week 3-4: stay no-equipment. Add anti-rotation, carries, and controlled jumping only if joints feel solid. Keep each sixpack workout! at 20-40 min/day.

Track three metrics weekly: waist, plank time, and one core strength test. Log everything. Use your phone, a sheet, or a watch like those in this performance tech breakdown.

If it’s not written down, it didn’t happen. Data beats feelings.

From here, progress is simple: keep this Abs Workout Challenge template, increase difficulty in 10% jumps, stay honest with tracking, and your shredded: defined core isn’t “someday.” It’s math, compound effort, and zero excuses, carried over week after week.Finish this Abs Workout Challenge with honest clarity. You built strength, stability, and better habits in just 2 weeks. Visible abs need time, consistency, and a smart calorie plan. Use your tracking data to spot real wins, not just the mirror. Repeat, progress, or step into a longer program with confidence.

Frequently Asked Questions

Can you get visible abs in 2 weeks with this Abs Workout Challenge?

You will not build deep, clear abs in just 2 weeks unless you already have low body fat and some core definition. This challenge can tighten your core, improve endurance, and make your abs feel harder and more stable. Visible abs depend mostly on body fat, diet, sleep, and consistency over many weeks, not a single short program. Use the 2 weeks as a strong start, then keep training 3–5 times per week while dialing in your nutrition to see real results.

Should I train abs every day during the 2-week challenge?

No, you don’t need to train abs every day during the 2-week challenge. Your core muscles need rest to repair and grow, just like any other muscle group. Aim for 3–5 focused ab sessions per week and use rest or light active recovery days in between to prevent fatigue and lower the risk of injury.

Is this Abs Workout Challenge effective without changing my diet?

The Abs Workout Challenge can help strengthen and define your core, but visible abs depend heavily on body fat levels, which are mostly driven by your diet. If you keep eating in a calorie surplus or rely on lots of processed foods, you’ll likely build muscle under a layer of fat you won’t see. For best results, pair the challenge with a simple, balanced eating plan: enough protein, fewer liquid calories and sweets, and mostly whole foods. Even small diet tweaks plus this workout can make a clear difference in 4–8 weeks.

Can I do this entire core program at home with no equipment?

Yes, you can complete the entire core program at home with no equipment by using bodyweight exercises like planks, dead bugs, side planks, and glute bridges. Just make sure you have a flat, comfortable surface and follow the sets, reps, and rest times as outlined. If a move originally uses equipment (like a cable or ball), you can swap it for a simple bodyweight version or a towel/broomstick variation. Focus on slow, controlled form, and you’ll get strong results without a gym.

What if I have lower back pain or need low-impact, no-jumping options?

If you have lower back pain or prefer low-impact moves, stick to no-jump options like marching, step taps, supported squats, and slow controlled core work that keeps your spine neutral. Avoid high-impact jumps, deep twists, or any move that sends pain down your leg, and always engage your core and land softly. If pain lasts more than a week, spikes during exercise, or includes numbness or weakness, stop and check with a physical therapist or healthcare provider before continuing.

How long will each workout take, and is 20-40 min/day enough?

Most workouts will take about 20–40 minutes, including warm-up and cool-down, and yes, that is enough when you train with focus and consistency. Aim for at least 3–5 sessions per week, mixing strength work and interval-style cardio to hit all major muscle groups and keep your heart rate up. If your schedule is tight, shorter but intense sessions (even 15–20 minutes) can still build strength, boost endurance, and support fat loss when paired with good sleep and nutrition.

What are the best exercises in this challenge for a stronger, defined core?

The best moves in this challenge for a stronger, defined core are planks (front and side), dead bugs, hollow holds, and slow, controlled mountain climbers. These exercises train your deep core, not just your “six-pack,” so you build real strength and better posture. Focus on form, breathe through each rep, and aim to progress by adding time, tension, or control rather than rushing.

Can I repeat this 2-week Abs Workout Challenge back-to-back safely?

Yes, most healthy people can safely repeat a 2-week abs workout challenge back-to-back as long as they listen to their body. If you feel sharp pain, strong fatigue, or lower back strain, take 1–3 rest days or switch to lighter core work instead. For best results and safety, mix in full-body strength, walking or cardio, and at least one rest or active recovery day per week. If you have past injuries, hernia, or back issues, check with a medical or fitness professional before repeating it.
