Mitochondria and performance:  how to train for more cellular energy

Mitochondria are like microscopic engines inside our cells, or the tiny power plants that convert nutrients into usable energy (ATP). While they often get mentioned in the context of endurance sports or health discussions, mitochondria are actually extremely important to nearly every aspect of athletic performance: strength, power, recovery, body composition, and longevity. Whether you’re […]Read More

Lactic acid: more than just metabolic waste

Lactic acid, long blamed for muscle burn and post-workout soreness, has been misunderstood for decades. Traditionally seen as a “waste product” of anaerobic metabolism, lactate has been for decades the villain in fatigue and poor performance. But what if the science has changed? Research suggests that lactate is not just a byproduct, but a powerful […]Read More

Metformin and Rapamycin for performance and longevity

Bodybuilding and longevity traditionally don’t go too well together, as we all know chasing size and strength often comes at some cost of long-term health. But what if certain compounds could extend lifespan while also enhancing muscle retention and performance? Let’s talk about Metformin and Rapamycin, two drugs initially developed for diabetes and organ transplant […]Read More

Understanding mTOR: a master regulator of hypertrophy and performance

Muscle growth isn’t just about lifting heavy weights and eating enough protein and carbs, it’s about activating the right pathways inside your body. One of the most powerful regulators of muscle hypertrophy and performance is mTOR (mechanistic or mammalian target of rapamycin). This cellular signaling pathway controls aspects such as protein synthesis, cell growth, and […]Read More

Oxygen Advantage: can breathing techniques make you stronger?

Strength training focuses on lifting heavier, eating smarter, recovering efficiently and ultimately getting stronger. But what if an overlooked factor, as simple as breathing, could dramatically improve strength, endurance, and recovery? The Oxygen Advantage, a system developed by breathing expert Patrick McKeown, introduces breathing techniques that claim to enhance athletic performance by improving oxygen efficiency, […]Read More

Testosterone vs. dopamine: balancing motivation and reward

Success in bodybuilding, business, and even life often comes down to two key circulating chemicals in the body: testosterone and dopamine. Acting as chemical messengers, these substances take part in regulating motivation, energy, and reward, but they also have a dark side. Constantly chasing quick dopamine fixes can lead to addiction and burnout, while unbalanced […]Read More

Psychedelics and recovery: can it help with CNS fatigue?

Central Nervous System (CNS) fatigue is always a concern for athletes and bodybuilders pushing their limits in training, especially for those who train close to failure frequently. Differently from muscular fatigue, which can be quickly recovered from with proper nutrition and rest, CNS fatigue affects overall neurological function, hormone regulation, and motivation. Traditional recovery methods […]Read More

Why the overhead extension is the superior triceps exercise

When it comes to building strong and well-developed triceps, many lifters choose to exercises like dips, close-grip bench presses, or cable pushdowns. While these are all effective, the overhead triceps extension stands out as arguably the best exercise for maximizing triceps growth and function. By emphasizing a full range of motion, optimal muscle stretch, and […]Read More

Strength meets flexibility: weight training and mobility

When most people think of weight training, they picture heavy lifts, muscle gain, and raw strength, and the first image that comes to mind is that of a bodybuilder that can barely tie his own shoes due to not being mobile enough. However, weight training can also be a powerful tool for improving mobility, or […]Read More
