I think of my body like A car, it needs maintenance. I eat well now, i drink water, lots. I work out a few days a week, i walk every night. I stretch and do yoga every morning and night.
It's a lot, and most people expect that they can just going on like normal without some type of change.
All my friends say the same thing, they are interested in still skating but they just complain without the motivation to attempt to fix whats wrong. I realize it isn't the more fun option, but it keeps me skating daily.
Sorry if that isn't the feel good "You got this" response the world expects now, but your 30's can physically be the best years of skating if you prepare/plan. Old enough to be done drinking too much and job/schedule stability.
I work hard to still be able to skate almost daily at 43, i sacrificed a lot.
But no, it doesn't get easier, if you lack structure in your personal life, that makes it even harder.
Good luck hope you find a happy medium.
