What is the best way to choose running shoes in 2026?

Choose running shoes by matching foot width, weekly mileage, primary surface (road, trail, track), cushioning preference, support needs (neutral, stability, motion control), injury history, and budget. Most runners benefit from a 2-shoe rotation: a cushioned daily trainer plus a lighter shoe for faster sessions.

What is Zone 2 heart rate training and why does it work?

Zone 2 is steady, conversational aerobic effort at roughly 60-70% of maximum heart rate. It builds mitochondrial density, fat oxidation, and aerobic base without producing fatigue, which is why endurance athletes spend 70-80% of weekly volume there.

How many calories should I eat to lose weight?

Subtract a 300-500 kcal daily deficit from your Total Daily Energy Expenditure (TDEE). A 500 kcal deficit averages about 0.45 kg (1 lb) of fat loss per week. Eat at least 1.6-2.2 g protein per kg bodyweight to preserve lean mass while losing fat.

What macro split is best for building muscle?

For muscle gain, aim for roughly 30% protein, 40% carbohydrate, 30% fat, with protein at 1.6-2.2 g/kg bodyweight and a 250-500 kcal daily surplus. Carbs fuel training intensity; fats support hormones.

What is the best fitness watch for runners?

The best running watch balances multi-band GPS accuracy, 20+ hour activity battery, wrist heart-rate plus optional chest-strap pairing, training-load and recovery metrics, and offline navigation. Top contenders in 2026 include Garmin Forerunner and Fenix, Coros Pace and Apex, Suunto Race, and Apple Watch Ultra for iOS users.

How long does it take to train for a marathon?

A first marathon typically requires 16-20 weeks of structured training from a base of running 3-4 times per week. Weekly mileage usually peaks at 50-80 km (30-50 mi) with one long run, one quality session, and easy aerobic volume. Add a 2-3 week taper before race day.

Are creatine and protein supplements safe?

Creatine monohydrate (3-5 g daily) and whey or plant protein are among the most studied sports supplements and are considered safe for healthy adults. Creatine improves strength and lean-mass gains; protein supports recovery and satiety.

What is VO2 max and how do I improve it?

VO2 max is the maximum volume of oxygen your body can use per minute per kg of bodyweight, the gold-standard measure of aerobic fitness. Improve it with 4-6 weeks of polarized training: 80% easy Zone 2 volume plus 20% high-intensity intervals (4x4 min at 90-95% max HR, twice weekly).

Do I need stability shoes if I overpronate?

Modern research shows pronation alone is a weak predictor of injury. Many overpronators run safely in neutral shoes if they are comfortable. Stability shoes (with guide rails or medial posts) help runners with persistent inward collapse, prior medial-side injuries, or who simply feel more controlled in them.

How much protein per day for fat loss while keeping muscle?

Eat 1.8-2.4 g protein per kg bodyweight per day during a calorie deficit. Higher protein preserves lean mass, increases satiety, and raises diet-induced thermogenesis. Spread intake across 3-5 meals of 0.3-0.4 g/kg each to maximize muscle protein synthesis.

What is the difference between BMR, RMR and TDEE?

BMR is energy used at complete rest, measured after fasting. RMR is similar but measured under less strict conditions, roughly 10% higher. TDEE adds activity, exercise, and the thermic effect of food on top of BMR or RMR.

How should beginners start running without getting injured?

Start with a 20-30 minute walk-run plan 3 days per week (1 min run, 2 min walk, repeated). Add 10% weekly volume, run on softer surfaces when possible, prioritize a comfortable cushioned shoe, and include 2 short strength sessions weekly to reduce common knee, shin, and Achilles injuries.

Which calculators does GearUpToFit offer?

GearUpToFit offers 16+ free calculators including BMI, TDEE, macro, body fat, calorie burn, heart-rate zones, VO2 max, running pace, one-rep max, protein intake, water intake, and Zone 2 calculators.

Is the 8-week fitness plan suitable for beginners?

Yes. Body Recomp OS adapts to your current fitness level, available training days, and goals — making it suitable for beginners through advanced trainees.

Does GearUpToFit review smartwatches and running watches?
