HIIT workouts are great for building lean muscle and burning fat. But does HIIT build muscle? Let’s find out!

High-intensity interval training (HIIT) is a hot topic right now, and it seems everyone has a different opinion on the subject. Some claim HIIT is the best thing to happen to cardio since sliced bread. Others say that since it doesn’t burn as many calories as steady-state cardio, it’s not worth your time. Still, others believe that because it burns so many calories and keeps you in fat-burning mode for hours after you’ve left the gym, there’s no point in strength training at all. So what do we say about this? Who’s right? Well, I’m here to tell you…
HIIT can help you build muscle and increase overall strength.
HIIT is a form of cardio that will help you build muscle and increase overall strength. If you’re looking to pack on some lean muscle, HIIT is the workout for you. It can be done at home using simple equipment such as a jump rope or resistance bands.
HIIT workouts are shorter than other types of exercise, so they’re great if your schedule is tight. For example, instead of spending 30 minutes on the treadmill at 3 mph with incline at 1%, try doing 3 minutes on an elliptical machine (or similar equipment) with 10-second bursts at 12 mph (or more).
HIIT works large muscle groups and pushes your heart to its max capacity.
HIIT works large muscle groups and pushes your heart to its max capacity. It’s a great way to build muscle and lose weight, but it can also help you get stronger.
It typically consists of 30 seconds of hard work followed by a few seconds of rest. You can do HIIT anywhere from three days per week to every day depending on what kind of results you’re looking for (and how much time you have!).
The high-intensity intervals are followed by recovery periods that allow your body to replenish energy stores (ATP) used during the activity. This is called “synergy” and allows you to perform at a higher intensity during subsequent high-intensity intervals.
You need a variety of workouts in your workout plan to see results.

To see results, you need to vary your workouts. You can do this by focusing on different muscle groups, doing different exercises and types of workouts, and varying the intensity of your HIIT sessions. HIIT:
- may not be the most effective way to build muscle.
- is not the most effective way to build muscle.
- may not be the best method for you.
- is not a magic bullet that will help you build muscle.
- is not the only way to build muscle, but it can be part of an effective workout routine.
You should eat enough food, including carbs, to fuel your workouts.

If you want to see results, you’ll need to eat enough food. This means that you should be eating enough calories to fuel your workouts and build muscle.
- Your calorie needs depend on your gender and weight, but the general recommendation is around 1-1.3g of protein per pound of body weight each day (this can be higher if you’re trying to build muscle).
- Carbohydrates are important for fueling energy during exercise, so make sure your diet includes them in reasonable amounts—the same goes for fat!
HIIT may burn more fat than traditional weight training, which can help with muscle-building if you are reducing your body fat percentage.

So, if you’re on a HIIT program and looking to build muscle, it’s best to use it alongside a low-fat diet that focuses on lean protein and complex carbohydrates.
Does HIIT build muscle?

The short answer is no — HIIT isn’t a good way to build muscle.
That’s because this type of workout relies on intensity rather than duration. As such, it doesn’t provide enough stimulus for muscle growth or strength gains over time. That said, HIIT does have other benefits that make it worth trying out from time to time:
It increases aerobic fitness (VO2 max) more effectively than steady-state cardio like jogging or running at the same intensity level. This means that you’ll be able to work harder during your HIIT workouts without feeling like you’re going to pass out!
When you exercise, your body breaks down muscle tissue to create energy. This is called catabolism, and it’s what happens when you’re not moving around much and your body needs to conserve energy.

Aerobic exercise — like jogging or cycling — helps improve the way your body uses oxygen, which increases your endurance and makes you more fit overall. However, it doesn’t build muscle tissue because aerobic exercise doesn’t require any extra energy beyond what your body already has.

Anaerobic exercise — like lifting weights or sprinting — requires extra energy to be created outside of normal cellular respiration and releases a lot more lactic acid into the bloodstream than aerobic exercise does. Lactic acid builds up when you’re doing anaerobic activity because it can’t be used immediately for energy production; instead, it has to be converted into glucose through gluconeogenesis (i.e., making sugar from non-sugar sources).
How HIIT can help you build muscle?
To understand how HIIT can help you build muscle, first you need to know how your body builds muscle in general.
Muscle growth occurs when your body breaks down more proteins than it can use for energy or other processes. The excess protein is then converted into amino acids that are used to repair damaged cells and tissues, including muscles. This process is called synthesis, and it leads to the growth of new tissue.
One way to encourage muscle growth is by creating an imbalance between synthesis and breakdown. You want synthesis — the rebuilding of damaged cells — to occur faster than breakdown — the breaking down of healthy cells for energy or other processes. High intensity exercise creates this imbalance because it causes your body to produce more stress hormones like cortisol and adrenaline, which stimulate protein synthesis in order to repair the damage caused by intense exercise.
HIIT training can help you reach your goals faster than any other cardio method
However, it is not the answer to all problems, though – it should be part of an overall plan that also includes weightlifting and proper nutrition.
HIIT training is a great way to build muscle, but it’s not the only way. You will also need weightlifting (with heavy weights) and proper nutrition.
HIIT workouts are difficult and may not be appropriate for everyone. If you’re overweight or have existing health conditions, talk to your doctor before starting a HIIT workout plan.
Conclusion
This is a complex question with no straightforward answer. The short answer is yes, but you need to know how to use HIIT and what it means for your goals. For example, if you want to lose weight, then HIIT will help you burn fat faster than any other method of cardio. If your goal is muscle building or strength training, however, there are better options out there that don’t require an intense workout every day (such as weightlifting).
FAQ about whether do HIIT workouts build muscle
High Intensity Interval Training builds muscle faster than traditional cardio workouts.
High-intensity interval training (HIIT) can be used for weight loss, fat burning, and building lean muscle mass. However, it’s important to note that HIIT doesn’t work for everyone, especially those who are overweight or obese.
High-intensity interval training will help you get strong, but it won’t make you any more muscular than if you did traditional cardio.
Strength training should be done before HIIT because it will help with muscle growth and increase your metabolism.
Both are great for building muscle mass, but if you want to build muscle quickly, then HIIT is better than weightlifting.
Weightlifting is much more effective than HIIT for building muscle mass.
Both are equally effective for weight loss, but if you want to burn fat faster than with HIIT, then you should use steady-state cardio.
HIIT should be done before lifting weights, because it will help you burn more calories during the workout.
