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'. []
If you are trying to gain size you can get fooled into believing you only need to work hard on the weights, or that cardio work is dull and boring. However, recent studies show that muscle gains were massively increased thanks to the incorporation of HIIT into weekly resistance workouts in place of dull, regular cardiovascular activity.
That's right, performing a high intensity cardio workout is actually superior not only for burning fat but also for building lean tissue! While this is probably music to the ears of all those gym enthusiasts who find cardiovascular activity to be somewhat dull, it does come with a few warnings.
If you are going to make the most of this great training method you need to understand a little about how it works. How many times have you seen bodybuilders jump onto bikes after a weight lifting session and pedal for upwards of 45 minutes to burn off body fat? This approach is now also considered to be yesterday's advice. Not only should they be doing high intensity cardio, they should be doing it prior to their weights. If you have been training for a while, this news will probably be a major shock to you because despite the fact there's a wealth of proof to back this approach up, most people do their cardiovascular work after resistance training.
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.
While regular cardiovascular exercise is good for your heart and certainly still has it's value, high intensity interval training is superior for both fat loss and lean muscle gains. If your goal is to learn the most effective ways to build muscle this year, then HIIT is certainly something you should be trying very soon.
