How To Fuel Your Gym Workout

The Energy Molecule

Adenosine triphosphate (ATP) is one of the most important molecules in the body, serving as the primary source of energy for basically all our functions.

This is especially true during heavy training and exercise when ATP is responsible for powering our muscles and keeping us going.

The process by which ATP is created involves a number of different molecules and nutrients, including fats, glucose, and creatine.

Glucose plays a particularly important role in ATP synthesis since it serves as the primary "fuel" that is delivered to the body's cells via our bloodstream.

Fats are also essential for this process, providing the bodies with a steady stream of fatty acids that can be used to synthesize ATP.

And finally, creatine acts as an essential substrate for ATP production, helping to ensure that our muscles have access to enough energy even during intense physical activity (well, at least for a short period before glucose kicks in.)

So basically, during each and every workout, your goal is to provide sufficient fuel for the continuous production of ATP, at an optimal rate.

Anaerobic Exercise

When it comes to gym training and any other high-intensity, short-burst activity, this is what we refer to as “anaerobic exercise” in the fitness world.

To simplify this terminology, anaerobic simply refers to an activity that is primarily fueled by processes in the body that don’t require oxygen to produce energy.

On the other hand, we have “aerobic” activities, which are the opposite - they primarily use fuel sources that require oxygen to produce energy.

During anaerobic, high-exertion activities, the body uses two primary sources of fuel to regenerate ATP and grant energy for sustained activity.

Those are namely creatine and glycogen (stored carbs.)

Carbs VS Fats

The question of carbs vs. fats has long been a topic of debate in the nutrition and health communities.

While there is no definitive answer to this question, one thing is clear: carbohydrates are the king of high-intensity performance.

This is true when we consider the role that muscle glycogen plays during exercise.

An even more important mention is the fact that fats cannot be broken down anaerobically, meaning that high-intensity training, like heavy, grueling gym sessions, require carbohydrates.

Overall, then, when it comes to high-intensity performance, carbs clearly come out on top.

And making sure we consume enough of them should be a priority for anyone looking to optimise their training results.

Carb Sources

Now, what are the best sources of carbohydrates, you may ask? Well, generally speaking, any carbohydrate will do, but the focus should be more on complex carbohydrates.

These are the carbohydrates that take longer to digest, grant more satiety and provide a consistent stream of energy.

Here is our top 5 list of our favourite carb sources:

1. Brown rice
2. Potatoes
3. Sweet potatoes
4. Wholegrain products
5. Fruits & veggies

Final Thoughts

When it comes to fuelling high-intensity performance, proper carbohydrate intake is essential.

Can you go without carbs? Yes, sure.

But you’ll likely perform sub optimally, and reach fatigue much quicker.

This is precisely why we recommend any strength-oriented athlete to consume their grains, and reap the gains!

As we always say, it is not recommended that you lean towards extreme “diets” but rather find a sustainable balance of all nutrients and implement it into a long-term plan of action.

Do you eat carbohydrates, and if no, why? Let us know in the comments below and let’s discuss!
