Episode 3245:
Steve breaks down the science behind muscle fibers, Type I, Type IIa, and Type IIb, and how they determine your natural strengths in endurance versus explosive power. With the right training, you can shift your muscle composition to align more closely with your goals, proving that genetics set the stage, but effort shapes the performance.

Quotes to ponder:
"Type I fibers are 'slow twitch' fibers. They use oxygen to fire, and they take longer to get going, but they can go for a longer period of time without getting tired."
"Type IIb fibers are 'fast twitch' fibers. These fire anaerobically (without oxygen), they fire extremely quickly, but they get tired easily."
"Your muscle fiber composition is already built into your genetics."
