How To Use Nutrition To Get The Most Out Of HIIT

By Russ Howe


Despite being very popular, HIIT is a subject which many people low very little about. It requires you to take a slightly different approach in your training in order to get the most from the multiple benefits it has to offer. If you're trying to discover how to build muscle with this style of exercise, then this is crucial.

Of course, we are talking about nutrition. In fact it is the pre-workout period of nutrition which we will be discussing in more depth today because this is the area which many people don't pay any attention to at all.

Before you workout you need to ensure that your body has been supplied with the best nutrients to perform the tough session ahead. If you do this then you can potentially increase your results by up to 30%, so it is worth taking a few moments to look into the latest science on the subject. []

Before you can work out what you should be eating prior to a high intensity interval workout you need to look at what type of food your body uses for fuel during this type of exercise because it's slightly different to regular training. While long, steady state cardio primarily burns fat stores, albeit at a very slow rate, high intensity intervals uses your carbohydrate stores for fuel.

The real benefits of this training happen after you leave the gym, where your body continues burning off calories at an increased rate for up to 14 hours. You may have heard this phenomenon called the afterburn effect. Instead of slowly chipping away at your fat stores and then ending the process when you leave the gym like regular cardio exercise, a high intensity workout depletes your carbohydrate stores first before going to work on fat stores. In doing this, your body enters a process called EPOC after your training has finished. It protects what little carb stores you have left and burns off excess fat instead. This process lasts an incredibly long time, and one calorie burnt during a high intensity session equates to around nine calories burnt during a long cardio workout.

So, the key thing we want to achieve is to help you burn through your body's excess carbohydrate stores while you are working out in the gym. For this very reason, consuming a high carbohydrate meal before a workout would make very little sense.

Does this mean you should train on an empty stomach?

Not quite. While you should look to avoid heavy carbohydrate sources before you train, you can actually increase your results if you use protein as this will work to protect your lean muscle tissue from being burnt off during an intense training. This means not only will you lose fat, you'll also hang onto and maybe even build more lean muscle tissue!

There are also many people who like using branched chain amino acids around their workouts. While this supplement is perfectly fine, there are better ways to do this. First of all, essential amino acids provide a better return than BCAA's as they include all of the amino acids which the body cannot naturally produce, rather than just the three which are more involved in building muscle. So look to replace your BCAA product with a reputable EAA supplement.

Most people who use the gym these days are familiar with protein shakes but they take them after they workout. Research reveals that you can dramatically increase your success if you also consume 15-20 grams of whey protein before you perform any high intensity activity, as well as your regular shake afterwards. This makes perfect sense because your body would naturally begin looking at your protein stores once it's carbohydrates are running low.

The topic of HIIT is as popular now as it has ever been in the past, but learning how to build muscle or lose weight with this approach often comes down to your nutrition plan surrounding those tough workouts. Now you have the key scientific research on the crucial pre-workout period, you'll be able to take your own results one step further.
