Is HIIT Good For Muscle Growth?

By Howe Russ


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.

Today we're going to be looking at this form of cardiovascular exercise and answering the all important question. Is it good for hypertrophy?

While there are certainly multiple benefits to be had from a good cardiovascular exercise plan, most people don't find cardio as interesting as weight training. This is particularly true with men, who seem far more interested in resistance workouts than hitting the treadmill or elliptical trainer.

Naturally, this behavior stems from a largely untrue stereotype that cardio is for women and weights are for men. This age old belief is something which has held countless gym members back for years and it's built upon lies.

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 is a massive difference between the steady pace of regular cardio, often billed as boring, compared to that of a high intensity session. Despite being performed on the same equipment, it's a completely different style of workout.

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.

The two primary energy sources we use during exercise are called aerobic and anaerobic. During regular cardio workouts we use our aerobic system. However, during both resistance training and high intensity intervals we use the anaerobic system instead.

Due to the fact that our body uses the same energy system during interval training as we do for resistance workouts, we actually burn calories in the same way. You may have already heard that a resistance workout causes your body to continue burning calories at an increased rate for hours after you leave the gym. This also happens with interval training, whereas regular cardio doesn't have these 'afterburn' benefits.

Despite growing in popularity over the last few years, HIIT remains a largely unused form of cardiovascular exercise. Most gym users believe that they need to punish themselves with long, dull sessions on bikes and treadmills to lose fat and it is simply not true. If you are learning how to build muscle more effectively, this form of training will work very nicely alongside your resistance training.
