This! 💯
Losing 10% percent of your strength, your VO2 max, muscle mass, or your bone density in your forties barely registers. You are a little slower on the hills, a small, seemingly insignificant number shifts on a scan, and life goes on. You’re busy. You’re not planning for life as an 80-year-old… but you should be. Because…
Trying to win back that same 10 percent in your seventies and beyond is a different fight entirely, and most people have no idea the rules have changed until they are trying to undo 20 years of bodily neglect.
That is the asymmetry no one warns you about. Decline is not a straight line you can walk back at any time you choose.
The biology of aging is unforgiving. Aging muscle becomes anabolically resistant, which means it responds less to the same training stimulus that built it easily when you were younger. The bone scaffolding you let erode does not fully rebuild. Our recovery slows, injuries come easier and linger longer, and the ceiling on what you can regain drops before you enter the gym for your first day. You are not just behind. You are climbing a hill that got steeper while you waited. Don’t get me wrong… this isn’t a reason not to start now… You will improve. But this is the note you send to your children.
The longevity conversation argues endlessly about what to do and almost completely ignores when. But the cost of waiting compounds. Every decade you delay, the interest on rebuilding increases, and at some point, the debt is simply harder to pay back than it ever needed to be.
None of this is about training in your forties and fifties to look good. You train to protect an option, the option to be independent at eighty, to carry your own bags, take your own stairs, and get up off the floor without a strategy. That option is bought decades in advance, or it is not bought at all.
Again… don’t despair… You can get back a lot if you start today. But sometimes I need to speak to the younguns that may be reading this… they need to know what lies just around the next bend.
