How To Use Nutrition To Get The Most Out Of HIIT

By Russ Hollywood


In gyms around the world nowadays, HIIT is everywhere. But if you are trying to learn how to build muscle and drop unwanted body fat using this method you need to pay particular attention to one area which most gym users overlook.

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.

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. []

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.

As you may already be aware, interval training's real benefits begin when you shut the gym door behind you as you leave. Your body enters a process called EPOC, also known as the afterburn effect by many trainers. This is where your body has lost so much of it's carbohydrate resources that it begins to shield what's left and instead uses your fat stores to provide you with energy. You guessed it, this results in increased fat burning and the phenomenon can go on for fourteen hours if you do thing effectively.

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.

This is why many people choose to workout on an empty stomach. But is this approach really the best way to maximize results?

Not quite. While performing interval training on an empty stomach is slightly more beneficial than performing it with a ton of carbs in your system, there is an even better way to increase results further. The biggest mistake people tend to make when watching their carbohydrate intake is forgetting to increase protein intake. As a result their body burns off a lot of muscle. To avoid this, simply increase your protein intake. This can be done by hitting the gym after a whey protein shake instead of a carbohydrate heavy meal.

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.

Secondly, science tells us that consuming your amino acids before your workout yields up to 30% higher uptake into the muscles, so ignore the common trend of mixing it with your post-workout protein shake. The perfect pre-workout cocktail before a high intensity interval training session would consist of around 15 grams of whey protein and a serving of essential amino acids.

Getting the right kind of nutrition into your system before you train can be crucial when performing HIIT sessions on a regular basis. Learning how to build muscle is often a game of opinion, with many exercise enthusiasts lost in a sea of misinformation. By looking at the very latest science on the subject, you can get more from every session in the gym.
