Carbohydrates For Bodybuilding - Mike Mentzer


In the dynamic world of bodybuilding and nutrition stands out as a cornerstone for achieving optimal results. Amidst the macronutrient discourse, carbohydrates take center stage. In this article, we delve into the carbohydrate landscape from the perspective of the legendary bodybuilder, Mike Mentzer. We will unravel the multifaceted benefits of carbohydrates in bodybuilding, examining their pivotal role in providing energy for workouts and their profound impact on cognitive function.


Carbohydrates and Bodybuilding

1. Muscle Glycogen Synthesis

Carbohydrates reign as the body's primary energy source, especially during intense workouts. Mike Mentzer's emphasis on glycogen, the stored form of glucose in muscles and the liver, highlights their critical role. Ensuring sufficient carbohydrate intake guarantees optimal glycogen storage, enhancing muscle performance, and fostering growth. Depletion of glycogen can impede muscle recovery and compromise overall athletic prowess.

2. Insulin Response

Mentzer championed the strategic consumption of carbohydrates to induce a favorable insulin response. Insulin, a key hormone, facilitates nutrient absorption in muscle cells. Consuming carbohydrates before or after a workout helps shuttle essential nutrients to muscles, promoting growth and efficient recovery.

3. Anabolic Environment

Carbohydrates play a pivotal role in creating an optimal anabolic environment for muscle growth. Maintaining an adequate carbohydrate intake prevents the breakdown of muscle tissue for energy, preserving hard-earned muscle mass.


Carbohydrates for Workout Energy

1. Glycogen as Fuel

In the throes of a workout, the body demands energy to perform at its peak. Carbohydrates, broken down into glucose, serve as the fuel for muscles. Ample glycogen stores ensure sustained energy, stave off fatigue, and enable high-intensity workouts.

2. Pre-workout Carbohydrate Timing

Mentzer recommended consuming carbohydrates before a workout to maximize performance. Providing the body with readily available energy ensures optimal strength and endurance during exercise. Complex carbohydrates like oats, whole grains, and fruits are ideal choices due to their gradual energy release, sustaining workout performance.

3. Post-workout Carbohydrate Timing

Critical for muscle recovery, replenishing glycogen stores post-workout is imperative. Consuming carbohydrates, preferably with protein, immediately after exercise aids in muscle glycogen repletion and promotes protein synthesis. This post-workout anabolic window maximizes muscle growth, repair, and adaptation.


Carbohydrates and Brain Function

1. Glucose as Brain Fuel

The brain's reliance on glucose for energy underscores the significance of carbohydrates. Mentzer stressed the importance of maintaining stable blood sugar levels through balanced carbohydrate intake to enhance cognitive abilities and mental focus.

2. Serotonin Production

Carbohydrates influence serotonin production, a neurotransmitter crucial for mood regulation. Adequate carbohydrate consumption boosts serotonin levels, supporting mental well-being and alleviating stress or mood disturbances that may hinder workout performance.

3. Mental Clarity and Concentration

By supplying a steady stream of glucose to the brain, carbohydrates enhance mental clarity and concentration. This is particularly vital for bodybuilders, ensuring focus during training sessions and maintaining the essential mind-muscle connection.



As advocated by Mike Mentzer, carbohydrates offer significant benefits for bodybuilders across various dimensions. Their role in optimal muscle glycogen storage, insulin response, and the creation of an anabolic environment is undeniable. Moreover, carbohydrates are indispensable for supplying energy during workouts, enhancing brain function, and fostering mental focus and concentration. Striking a balance in carbohydrate intake is key to achieving the best results in your bodybuilding journey, considering individual needs, activity levels, and goals. Remember, harnessing knowledge and smart utilization of carbohydrates can be a potent tool in your pursuit of peak performance and a sculpted physique.

We realized that we only have so much energy to spare before we have to recharge our batteries.

We only have so much time to spend in the gym due to work, family, friends and responsibilities.

Knowing that time and energy are limited resources, it only makes sense to make the most of them, right?

That’s exactly what High Intensity Training does.

It is designed to reach the point where the maximum muscle growth can occur without ‘spilling over’ and wasting precious energy.

Energy that could be used to aid the recovery process.

That way each workout is short, intense.

Our High Intensity Training can be summed up thusly:

Low Volume

Heavy Weight

Adequate recovery

Train to Muscle Failure

This High Intensity Training is low volume but pushes your muscles to the absolute limit and beyond..
