Is HIIT Good For Muscle Growth?

By Russ Howe


Despite growing in popularity over the last ten years or so, HIIT remains an area of health and fitness still shrouded in mystery. If you are attempting to determine how to build muscle effectively this is one area you definitely need to look into.

This is a form of cardiovascular activity with a major twist. Today we're going to look at this in more depth and answer the question everybody is asking. Is this a good form of exercise for muscular growth?

If most men were honest, they'd happily admit that they don't do enough cardiovascular exercise. It's often seen as the boring alternative to resistance training and they don't have the same level of drive for it.

This is largely because there is a false mentality in most gyms that cardio is for girls. Most guys deem it too boring and not engaging enough.

In fact, everybody needs to do some form of cardio if they want to get fitter and stronger. No matter whether your are a man or a woman, if you wish to get leaner you should be performing some form of cardiovascular exercise alongside your resistance routine. One of the best methods is high intensity interval training.

There are several key differences between high intensity cardio sessions and steady state workouts. If you've ever used an exercise bike for an hour at a steady pace you've probably felt a little bit bored at certain stages. That's one of the main drawbacks to this style of training and something which high intensity sessions will eliminate.

Interval training is very simple when you get down to the finer details of it. Basically your aim is to switch from a moderate level to a high level every so often, causing your body to be unable to adapt. This will have similar effects on your muscles to a resistance workout.

First of all, which energy system does your body use when you are training with weights? Your anaerobic energy system. During any high intensity interval workout you'll be tapping into the exact same energy resource.

Secondly, one of the best things about resistance training is that the calories continue to be burnt by your body for up to sixteen hours after your session ends. This phenomenon is known as Post Exercise Oxygen Consumption and the exact same phenomenon occurs after a high intensity cardio workout. While you stop burning off calories the moment your regular cardiovascular workout finishes, interval training helps you to carry on even after you have left the gym.

As you can see, learning how to build muscle isn't necessarily all about hitting the weights. HIIT is a great way to increase lean tissue, with the added benefit of stripping away unwanted body fat at an increased rate.
