Strength After 40

Something quietly changes after age 40. Sarcopenia — the involuntary loss of muscle mass and strength — accelerates from roughly 0.5% per year in your thirties to 1–2% per year in your forties and beyond. The decline is invisible at first; you don't notice it the way you notice a pulled hamstring. But over a decade it compounds into the difference between an active sixty-year-old who still hikes, travels, and lifts groceries effortlessly and one whose world has slowly contracted to whatever doesn't require strength. The good news: in adults of every age studied — including people in their eighties and nineties — properly programmed resistance training reverses the trajectory. This pillar is for everyone over forty who wants to keep the life they have. We cover what changes physiologically (recovery, joint resilience, hormonal context), what doesn't change (your fundamental ability to build strength is remarkable well into your seventies and beyond), and the specific programming choices that matter more once you're past forty: prioritizing compound movements, dialing intensity on autoregulation rather than ego, treating recovery as a first-class part of training rather than an afterthought. Dorsi defaults to a programming model that's well-suited to lifters in their 40s, 50s, and 60s — moderate volume, high attention to recovery signals from your Apple Watch, gentle progression. The articles below explain why this approach works; Dorsi delivers it as a routine you can actually stick with.
