https://go.chasingstrength.com/kettlebell-maximorum-e/After 40, you're not losing strength first. You're losing power — and it's happening 2-3x faster than you think.
Most men over 40 feel "strong enough." But power fades at 2.0–3.5% per year while strength only fades 1.0–1.5%. By the time the loss is obvious, you've already lost a decade.
In this video, I break down 5 science-backed reasons why Power-Endurance training is non-negotiable for men over 40 who want to stay strong, capable, and independent — not just in the gym, but in real life.
What you'll learn:
- Why power craters before strength does (and the chair test that proves it)
- How your body is quietly converting fast-twitch muscle into slow-twitch muscle check here — and how to stop it
- Why cardio alone is rusting your brain-to-muscle wiring
- Why your 1-rep max is the wrong thing to train after 40
- How Power-Endurance gives you two adaptations for the price of one session
