For me, it is just making sure I build a life around movement and fitness. I was naturally skinny and didn’t work out at all until I was 30 but in the 8 years since, I have gone from not being able to do a single sit-up to doing home workouts and then on to lifting weights, doing Barre, Orangetheory, Solidcore. When gyms closed during Covid I challenged myself to become a runner and did that; I walk anywhere I possibly can, I take vacations that include physical activity like hiking, kayaking, climbing.
There’s not one goal of “run x distance” or “weigh y lbs.” For me it’s just about always finding ways to be active that I enjoy and have fun at and push me to help me grow. Stay active , treat my body as if it’s got to last me til I’m 100.
