Is HIIT Primarily For Weight Loss Or Muscle Building?

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?

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.

Many individuals wrongly presume that cardio exercise is purely for weight loss, or they believe the age old misconception that treadmills are for women and weights are for guys.

Believe it or not, if your main target in the gym is to build more lean muscle then cardiovascular exercise will indeed play a huge role in your accomplishments. There are several effective forms of cardio which improve fitness and hypertrophy, most notably 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.

By constantly changing the resistance and intensity level of your gym session you will be able to challenge your body in ways it has never been pushed before. In fact, many of the benefits to this type of training have more in common with weights than they do with cardiovascular exercise.

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.

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.

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.
