@longevity_enthusiasts: YOUR “STEP-CATCHING” MUSCLES START DYING IN YOUR 30s ⚡ Step off a curb unexpectedly - and catch yourself before you fall? That’s thanks to type 2B muscle fibers - the explosive fast-twitch fibers in your feet and lower legs. They’re the first to shrink with age. By your 30s, they’re already in decline. By your 70s, losing them is one reason falls are so common. It’s not just a balance problem. It’s a power problem. Without those fibers, your body can’t react fast enough to save you from a stumble. But you can train them. Jumping. Plyometrics. Fast, controlled movements. Train now - so 40 years from now, you’re still quick on your feet.
