Read this to educate yourself 😎 Made it super duper easy for you to understand 😁 • the Size Principle and Henneman’s SIZE principle. Picture this: your motor units, like skilled software, activate muscle fibers under the brain’s command. As fatigue sets in and the need for more power arises, bigger motor units join the party, controlling those high-output muscle fibers. Lifting heavy weights? 🏋️♂️ You’re calling in the big guns right from the get-go, engaging nearly every motor unit (80%+ of 1RM). Going all-out to failure? 🥵 You’re near-maxing motor units, too. Lighter loads and high reps get close, but not quite maximal. the kicker: when those fibers haul out serious force due to slow contractions (near-failure mode), that’s when the magic happens—mechanical tension! 🎩✨This is why diverse rep ranges bring similar muscle gains to the table. 📊 Wait for it—brace yourself—because it’s the SAME deal whether you rep out 5 times at your 5RM max or rock 15 reps at your 15RM. Anecdotal evidence? “My legs loved higher reps, they grew more right after i changed!!” 🦵📈 Perhaps you were just giving it your all, dialing in that extra effort, and getting more motor units in on the action. But, hey, there’s no magic in those higher reps. So, next time you’re in the gym, remember: the real growth happens when those muscle fibers bind with mechanical tension, no matter the rep range.💥🏋️♀️💥
