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

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.
