Muscle power is not just about lifting heavy weights or running faster; it encompasses the ability of your muscles to exert force quickly. It’s crucial for everyday activities, from climbing stairs to lifting groceries, and even more for athletic performance. 

Boosting your muscle power can improve overall health, increase metabolism, and enhance physical capabilities. Balancing diet and exercise is key to optimizing muscle power—these elements interact and might hold more sway in building muscle power.

What is the role of diet in building muscle?

Diet serves as the cornerstone of muscle power. Without proper nutrition, muscles lack the necessary fuel to perform, recover, and grow. Let’s break down a diet’s critical elements that support muscle power [1].


The main nutrients needed in large quantities for energy and muscle power are called macronutrients:

  • Protein: Essential for muscle repair and growth, proteins are the building blocks of muscles. Sources include lean meats, fish, eggs, dairy, legumes, and plant-based proteins like tofu and tempeh.
  • Carbohydrates: Provide the energy needed for daily activities and intense workouts. Complex carbohydrates such as whole grains, vegetables, and fruits offer sustained energy, while simple carbohydrates can give quick energy bursts.
  • Fats: Support hormone production and overall energy levels. Muscle function depends on healthy fats, which can be found in fatty fish, nuts, seeds, avocados, and olive oil [2]. Particularly omega-3 fatty acids have anti-inflammatory qualities that promote muscle repair.

Getting the most out of these macronutrients is essential for maximizing both total health and muscle power.


Micronutrients are essential for overall health and muscle strength, even though they are required in smaller quantities than macronutrients. They include vitamins and minerals essential for energy production, muscle function, and recovery.


  • Vitamin D: Crucial for calcium absorption, which supports muscle contractions and bone health. Sources include sunlight exposure, fortified foods, and supplements.
  • B vitamins: Vital for energy metabolism; these vitamins help convert food into usable energy. They are found in whole grains, meats, and leafy greens.
  • Vitamin C: An antioxidant that helps repair tissues and aids in collagen production, necessary for healthy muscles and tendons. Found in citrus fruits, berries, and vegetables.


  • Calcium: Vital for healthy muscles generally and for muscular contractions. Fortified meals, leafy greens, and dairy products are good sources.
  • Magnesium: Supports muscle function and energy production, helping to reduce muscle cramps and fatigue. Whole grains, nuts, and seeds are good sources of magnesium.
  • Potassium: Regulates fluid balance and muscle contractions. Bananas, potatoes, and spinach provide ample potassium.
  • Iron: Critical for oxygen transport to muscles, enhancing performance and endurance. Red meat, beans, and fortified cereals are excellent sources [3].

Adequate intake of these micronutrients ensures optimal muscle performance and recovery.

Water is a major component of muscle tissue and is crucial for muscle contractions and the transportation of nutrients. Dehydration can cause fatigue, cramping, and decreased performance.

It’s critical to maintain a regular water intake throughout the day, particularly before, during, and after physical activity. Consuming electrolyte-rich fluids can help replenish lost minerals during intense exercise. 

Proper hydration supports optimal muscle function, aids in recovery, and enhances overall athletic performance. Remember, staying well-hydrated is key to maintaining muscle power and preventing injury.


Before working out, eat a balanced lunch that includes protein and carbohydrates to provide the energy you need to perform at your best. Within 30 to 60 minutes of working out, eating a meal or snack high in protein promotes muscle growth and repair.

Small, frequent meals throughout the day maintain energy levels and support continuous muscle protein synthesis. 

Proper nutrient timing ensures muscles receive the necessary fuel and recovery nutrients when needed most, enhancing overall muscle power and performance.

How does exercise increase muscle strength?

Exercise stands as a cornerstone in building and enhancing muscle power. It stimulates muscle fibers to grow stronger and adapt to increased demands, ultimately improving overall physical performance [4]. 

Different types of exercises target muscle power in various ways, each contributing uniquely to the overall goal.

Types of exercise

Exercise is essential for building muscle power, and different types target this in unique ways:

Resistance training

Activities like weight lifting, bodyweight exercises, and resistance bands directly enhance muscle strength and power. 

Examples include squats, deadlifts, bench presses, and push-ups. Resistance training works by causing muscle fibers to break down and rebuild stronger, promoting muscle growth and power.


Known for explosive movements, plyometric exercises such as jump squats, box jumps, and burpees train muscles to contract quickly and forcefully. 

This type of exercise improves the rate of force production, crucial for activities requiring quick bursts of power like sprinting or basketball.

High-intensity interval training (HIIT)

Combining short bursts of intense activity with rest periods, HIIT includes exercises like sprints, cycling, and circuit training. HIIT enhances both cardiovascular fitness and muscle power by pushing muscles to work at their maximum capacity for brief periods.

Incorporating a mix of these exercises can lead to well-rounded muscle power development, improved performance, and overall fitness.

Training principles

Effective training for muscle power involves adhering to key principles that ensure continuous improvement and prevent plateaus.

  • Overload: To promote muscle growth and strength, progressively increase the resistance or intensity of your exercises [5]. Increased weight, more repetitions, or shorter rest periods can all help achieve this. Overloading challenges the muscles, causing them to adapt and grow stronger.
  • Progression: Gradually increase the difficulty of your workouts to avoid injury and ensure steady improvement. This might involve heavier weights, more complex movements, or longer workout sessions. Consistent progression keeps muscles engaged and developing.
  • Specificity: Tailor your exercises to target specific muscles or movements relevant to your fitness goals. For instance, a sprinter focuses on explosive leg exercises, while a swimmer emphasizes upper body strength. Specificity ensures your training regimen effectively addresses your desired outcomes.

Following these principles helps in building muscle power efficiently and safely, leading to better performance and overall fitness.


Muscle repair and strengthening occur during rest, not during workouts. Adequate sleep and rest days are essential to allow muscles to recover and grow. Overtraining can lead to fatigue, injury, and diminished results.

Incorporating active recovery, such as light stretching, yoga, or low-intensity activities, helps maintain flexibility and reduce muscle soreness

Paying attention to your body’s signals and giving it the time to heal will lead to more effective and sustainable muscle power development.


Regular workouts yield far better results than sporadic efforts. Establishing a consistent exercise routine ensures continuous progress and helps maintain motivation. A balanced schedule that includes resistance training, plyometrics, and cardiovascular exercises promotes comprehensive muscle development.

Monitoring your development will hold you responsible and show your advancements over time. Using tools like the Longevity.Technology Epigenetic & DNA Test can provide personalized insights into your genetic predispositions and help tailor your fitness plan for optimal results.

Making exercise a regular part of your day helps you develop healthy habits. Setting and maintaining objectives for general fitness and muscle power requires a commitment to frequent training sessions.

What is the best supplement for muscle growth?

Supplements can significantly enhance muscle power, providing nutrients that might be challenging to obtain from diet alone. While a balanced diet should always be the foundation, supplements can offer an additional boost for those looking to optimize their muscle power.

Protein supplements

They provide a convenient way to meet protein needs, especially post-workout, aiding in muscle recovery and enhancing overall muscle power [6]. Perfect for those with high protein requirements due to intense training.


Creatine enhances muscle power by increasing ATP production, providing more energy for high-intensity activities. 

Regular supplementation improves strength, muscle mass, and power output, making it highly effective for weightlifting and sprinting. It’s one of the most researched and proven supplements for boosting athletic performance and muscle growth.

Branched-chain amino acids (BCAAs)

BCAAs, including leucine, isoleucine, and valine, support muscle protein synthesis, reduce muscle soreness, and decrease exercise-induced muscle damage. They provide immediate fuel during prolonged exercise or fasting, promoting muscle recovery and growth

BCAAs are particularly beneficial for enhancing performance and recovery in high-intensity training sessions [7].


Caffeine boosts endurance, reduces perceived exertion, and enhances strength during workouts. Ideal for short, intense training sessions, caffeine provides a temporary performance boost, helping athletes push harder and achieve better results.

Omega-3 fatty acids

Omega-3 fatty acids in fish oil support muscle recovery through their anti-inflammatory properties. They help reduce muscle soreness and enhance the anabolic response to protein consumption. 

Beneficial for those in intense training, omega-3s aid in faster recovery and improved overall performance.
