Can You Build And Maintain Muscle With HIIT?

By Russ Hollywood


Unless you have been living under a rock for the last three-to-four years, you have probably already heard about high intensity interval training. However, one of the biggest questions surrounding this training method is quite difficult to find an honest answer to - can you build lean muscle with it or is it reserved for fat loss workouts?

The old approach, of course, is to do a resistance session and then jump on a bike for some light cardiovascular work to get yourself into the so-called 'fat burning zone'. []

This has now been proven incorrect, as the benefits of modern science have become very important to many professionals within the fitness industry. Thanks to these benefits, we can now see that HIIT is indeed one of the best approaches when it comes to both fat loss and lean gains.

You read that correctly - performing a HIIT workout has been proven by modern science to burn off more calories and promote more lean muscle growth than regular, steady state cardio. If you find the prospect of an hour on the bike to be pretty dull, then this discovery should really appeal to you.

It would be foolish to jump straight in, of course, without taking a few minutes to learn some of the basic principles which HIIT operates around. People often buy into opinions in the fitness world, rather than stone cold facts. They follow the advice of their friend purely because he's in shape, despite the fact that the advice offered little or zero scientific support. This is why so many people don't get results in the gym. For instance, most people do their cardio work after they hit the weights. Based on recent studies, not only should you be doing HIIT you should also be doing it before you hit the weights.

A Canadian study found that cardio exercise followed by weight training was vastly superior to doing it afterwards, both for fat loss and lean muscle retention. This study dates back to 2001, but was vastly under-reported and so it went under the radar of many trainers.

Of course, it is also important to discuss the increased difficulty which will be served up by a HIIT workout in comparison to regular, steady state endurance exercise. You won't be able to do this every day of the week, particularly if you are also doing resistance training. That's actually a good though, though, as it will allow your body to recuperate fully.

If you have been trying to learn how to build muscle in the gym but were perhaps unsure of high intensity interval training due to the fat loss stigma which is attached to it, you need not worry. HIIT has been proven to retain lean muscle mass in a far superior way to regular cardiovascular activity, allowing you to slot it into your program and get the best of both worlds.
