I train, and I intend to still be training in forty years. This chapter is about why, and none of it is about how anybody looks.
The goal is narrow and I can state it exactly. Strong, mobile, and unafraid of my own body at eighty. Able to pick up a grandchild, get down on the floor with them, and get back up again without thinking about it. Still walking the hard trail at seventy-five, because neither of us ever stopped being able to.
Most of what wrecks people late is not disease. It is thirty years of not moving, and it compounds exactly the way debt does.
The emphasis falls on flow rather than mass: strength that transfers to real objects, and mobility kept deliberately, because mobility goes first and it is expensive to buy back. Add enough conditioning to be useful in an emergency, and eating like an adult most of the time, without turning food into a moral system or being tedious about it at somebody else's table.
The boring version is the one that works. Show up often, go slow, add a little, sleep properly, and do not get hurt. Nothing about it is impressive on any given Tuesday, and the entire return sits in the fact that it never stopped.
Most of it should be outside and useful, which means splitting wood, hauling, digging, and climbing something because it happens to be there. A body kept by living, not by an hour indoors compensating for the rest of the day.
The sleep half gets taken as seriously as the training half, which almost nobody manages. It is the single largest lever, it is free, and it is the first thing both of us will sacrifice when the work gets loud. I would like us to be the couple that guards it anyway.
I will get injured at some point, because everybody who keeps moving for decades does. The plan is to rehab it properly, come back smaller, and build again, instead of quitting and calling it age.
Now the part I want to be careful about.
I am not describing a body anybody has to have. I am describing a practice I keep, and I would like company in it.
Her weight, her size, where she is starting from, and whether she has ever set foot in a gym are all beside the point. Bodies change, and they change hardest around exactly the things I said I wanted in chapter four: pregnancy, recovery, injury, age, and the stretches where training simply is not the priority and should not be.
There will be seasons where one of us carries the other one's share of the physical work, and that is not a debt anybody repays. That is the arrangement working.
I also have no intention of being her coach. If she asks for help I will help, and if she wants it left alone then I leave it alone, and a stray comment never turns into a program. I have watched that dynamic poison things.
The movement should be shared wherever it can be: long walks that are actually the conversation, a trail we do every year and can measure ourselves against, and something neither of us is any good at, learned late and badly, together.
The partner I am hoping for intends to keep her body for the long game, whatever that ends up looking like for her. Somebody who moves on purpose.
That is the requirement, and it has nothing to do with a mirror. Everything else about this practice is quiet, and its whole payoff sits decades away, in the chapter this book ends on.
