Muscle Growth

"Strength" and "power" get used interchangeably in the gym, but they're distinct qualities that respond to different training — and training one doesn't automatically train the other. If your goal involves jumping, sprinting, throwing, or any sport where speed of force matters, understanding that distinction changes how you should train. Strength vs. Power: Two Different Questions Strength is the ability to produce force. Power is the ability to combine a high force output wi

Whether you're logging trail miles in the foothills above Salt Lake City or training for your first race around the valley, endurance performance comes down to more than just putting in miles. According to The RP Diet for Endurance, how you manage body composition, fuel, and hydration has just as much impact on your race times as your training plan itself. Leaner Isn't Always Better — But It Usually Helps Endurance performance favors leanness more than almost any other sport,

Walk into most gyms and "stability training" usually means a Bosu ball, a wobble board, or some single-leg exercise done on an unstable surface. Real stability isn't something you train with gadgets — it's the foundation that lets you produce force safely in the first place, and the best way to build it is with the barbell you're already using. A Stable Base Is a Training Principle, Not an Accessory For nearly every compound lift, having a stable base means being properly bal

Getting stronger isn't just "lift heavy things." Strength is built through two core training principles and four distinct adaptive systems in the body — and understanding them changes how you should structure your training. Specificity Comes First The most important principle in strength training is specificity: your training has to stimulate the exact systems that produce the performance you want. Specificity exists on a spectrum. Practicing the competition lift itself is th

If you've spent any time in a gym, you've heard the theories: lift heavy for "real" gains, chase the pump, or just get sore enough and you'll grow. The truth is that muscle growth (hypertrophy) isn't caused by one single thing — it's driven by a handful of measurable stimuli working together, some more powerful than others. Here's a breakdown of the main theories and stimulators of hypertrophy, and what they mean for how you should actually train. The Big Three: Tension, Meta
