Rule #3 for men over 40 (Stop your set when THIS happens – most guys never do)

🔗 https://cart.chasingstrength.com/strong4 Most guys over 40 are grinding their reps into the ground — and wondering why they're not getting stronger. Here's Rule #3: Stop your set the moment your rep speed slows down. Not at failure. Not when it "gets hard." The instant the first rep slows — you rack it, park it, and walk away. Sounds soft. It's the opposite. When your rep speed drops, your fast-twitch muscle fibers — the ones responsible for strength, power, and the physique you actually want — have already hit their limit. Every rep after that? You're training your slow-twitch fibers, reinforcing poor movement patterns, and hammering your HPA axis. Over time, you're literally converting your fast-twitch fibers into slow-twitch ones. The science calls it MHC IIX downregulation. I call it getting weaker on purpose. This is what separates training by SIGNAL from training by suffering. If you're a man over 40 who's serious about building real strength — not just surviving your workouts — this is the rule that changes everything. 🎯 In this video: Why grinding reps destroys fast-twitch muscle fibers over 40 What rep speed actually tells you about your neuromuscular state How autoregulation protects your recovery AND accelerates your gains The one signal that tells you the set is done — every time 📌 Want the full system? https://cart.chasingstrength.com/strong4
