Personally, I found myself getting injured easier and easier every year growing “older” (I’m still only on my 30s). Whether it was neck pains from working on the desk or leg injuries from falling on BMX or a mountain bike.
It’s been a year now I’ve been training multiple times a week in gym, sessions with PT, group trainings and solo, and kinda starting to enjoy it - looking forward for the next training session even if it’s just 2 days apart.
I envy the motivation you have.
I don’t even have that level of commitment to the things that i love, let alone maintenance.
Learning to love the process is hard, once you do, getting knocked off your routine is annoying.
