How To Fuel Your Gym Workout

Experiencing low levels of energy while training? Learn how to fuel your workouts here!

Whether you're a regular at the gym or just starting out, proper fueling is essential to getting the most out of your workout.

There are certain eating habits that can lead to fatigue and decreased performance.

Conversely, other eating habits can do the opposite - fuel your workout and optimize performance.

In this post, we'll discuss some tips for healthy pre-workout eating habits that will help you power through your next sweat session.

Let's get started!

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 human body 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 optimize 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 favorite carb sources:

1. Rice

2. Potatoes

3. Sweet potatoes

4. Wholegrain products (like oats)

5. Fruits & veggies

Final Thoughts

When it comes to fueling 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 I 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.

Machines vs. Free Weights: A Comprehensive Look at Strength Training

February 10, 2025

The debate over the superiority of machines versus free weights in strength training has persisted for decades. If you’re searching for a personal trainer in Nashville to help you navigate your fitness journey, understanding the roles of both training methods is essential. Rather than viewing them as competing approaches, it's crucial to recognize how they complement each other in an effective workout program. Machines: A Controlled Environment Machines offer a structured and guided approach to resistance training, making them a staple in almost every gym. Their defining characteristic is the fixed path of motion, which stabilizes the weight and controls movement. This design simplifies strength training, making it accessible to a broad audience, including beginners and those recovering from injuries. For individuals new to personal training in Nashville TN, machines can provide a safe introduction to resistance training. They help users focus on primary muscle engagement without worrying about balance and stabilization. For example, performing a chest press on a machine allows users to isolate the pectorals and triceps without the additional challenge of stabilizing a free weight. However, the structured nature of machines can also be a limitation. Since they guide the user along a predetermined path, they may not accommodate natural joint movement, potentially leading to discomfort or reinforcing imbalances over time. Additionally, machines often bypass stabilizing muscles, which are crucial for functional strength and overall balance. Machines shine in rehabilitation settings, allowing targeted muscle engagement without overloading injured areas. They are also highly beneficial for bodybuilders focusing on muscle isolation. By eliminating the need for stabilization, machines enable lifters to apply greater intensity to specific muscle groups without compromising form. Free Weights: Freedom and Functionality Free weights—including barbells, dumbbells, and kettlebells—offer unrestricted movement in multiple planes, making them highly effective for building functional strength. This versatility makes them an excellent choice for athletes and individuals seeking fitness training in Nashville that translates to real-world activities. Unlike machines, free weights demand more from the user, engaging a broader range of muscles with every exercise. For example, a barbell squat not only strengthens the quadriceps and glutes but also recruits the core, back, and smaller stabilizing muscles to maintain proper posture and control. Free weights allow for greater flexibility in workout design, with countless variations of exercises that can be tailored to specific goals. However, this freedom comes with a steeper learning curve. Without proper guidance, improper technique can lead to injury. This is where working with personal trainers in Nashville TN can be invaluable. Free weights are particularly effective for compound lifts such as squats, deadlifts, and presses, which work multiple muscle groups simultaneously. However, they can be intimidating for beginners who struggle with form or balance. This is where combining machines and free weights strategically can be beneficial. The False Dichotomy The debate between machines and free weights often presents them as opposing choices, but the truth is they serve different purposes and can coexist within a well-rounded training program. The best approach isn’t about choosing one over the other, but about utilizing both based on individual goals, experience level, and training context. For beginners, machines build confidence and establish foundational strength. As they progress, incorporating free weights enhances balance, coordination, and functional strength. For advanced lifters, machines provide a means to isolate specific muscles after heavy compound lifts. For example, a well-structured leg workout might include barbell squats to develop overall strength and coordination, followed by machine-based leg presses to target the quadriceps with greater intensity once stabilizing muscles are fatigued. Beyond the Gym The discussion also extends beyond gym settings. Many proponents of functional fitness argue that free weights better prepare the body for everyday movements like lifting, carrying, and climbing stairs. These activities require the integration of multiple muscle groups, similar to free-weight exercises. But one thing I am steadfast in saying is that “a strong body is a functional body.” So, any form of training that has a progressive strength element to it should be viewed as “functional,” whether it be machine or free weights. Yet, not everyone trains with functional fitness as their primary goal. For bodybuilders focusing on muscle hypertrophy, machines provide an efficient way to target specific muscles without exhausting stabilizers. This makes them particularly useful for individuals working with personal trainers in Nashville who specialize in body recomposition and aesthetics. Conclusion The choice between machines and free weights isn’t about right or wrong—it’s about how each fits into a well-designed training program. Machines provide safety and simplicity, making them ideal for beginners and focused isolation work. Free weights offer versatility and what is viewed as a more functional strength development, challenging the body in ways that extend beyond the gym. Instead of viewing them as competing options, think of machines and free weights as complementary tools. A personal trainer in Nashville TN can help you develop a program that strategically integrates both, ensuring optimal results based on your fitness level, goals, and needs. By leveraging the strengths of each method, you’ll maximize muscle growth, minimize limitations, and create a sustainable training regimen for long-term success.
