How To Use Nutrition To Get The Most Out Of HIIT

By Russ Hollywood


If you are trying to learn how to build muscle with HIIT then you may have noticed how much confusion surrounds this popular training method. Despite it's huge popularity, many people make some crucial mistakes when designing their high intensity interval program.

Nutrition is a key factor in improving your results from any high intensity workout program. The pre-workout period is an area where most people have no idea how to get the best nutrients for their muscles, so this is what we will be focusing on today.

If you have been working out for some time already then you'll already understand how important it is to give your body the correct type of nutrients to make the most of each session you do. However, many people don't realize that high intensity training requires a slightly different tactic than regular exercise. []

The first thing you must do to get the right nutrients before a hard workout is look at which energy source you'll be using in your session. While long, steady-state cardiovascular workouts tend to slowly chip away at your body's fat storage, intervals do not do this. Instead, they mainly use your glycogen (carb) stores.

If you have done your research you will already know that the major benefits of high intensity interval training take place outside of the gym, during the recovery period after your workout. This process, known as EPOC, is where your body tries to protect what's left of it's carbohydrate reserves and focuses on burning body fat for the fuel it needs in order to function properly. Carbs are your body's primary energy source, so when you have burnt through most of your body's reserves it's going to work hard to protect what little it has left, switching the focus on other nutrients instead. This magical post-workout effect can last a whopping 14 hours if you get it right.

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 all of those people who insist on training first thing in the morning on an empty stomach are actually onto something?

Actually, no it's not. While it is more effective than training after a carb heavy meal, there is an ever more superior method. Research shows that consuming a good source of protein before a workout increases both fat loss and muscle retention even further. Remember, in the absence of enough carbs to handle your workout there is a chance your body will turn to protein as a fuel source. By consuming a whey protein shake before a workout you buffer your body's supply and hang onto your hard earned 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.

Furthermore, consuming your serving pre-workout as opposed to post-workout has been shown to increase muscle uptake by around 27%. Combined with a whey protein shake, you'll be able to protect your body from any lean tissue breakdown and fight off any feelings of hunger while performing high intensity training and burning through those carbohydrate reserves.

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.
