Well I blew my knees when I was 21 doing mountain bike rides where I went up a vertical mile. The summer between undergrad and grad schools I remember riding my bike to a Ross Perot rally and being in agony. I've found a lot of things I can do but I have to be sparing about running and can't even look at a bike anymore. I did enough heavy cardio training to get abnormal findings in my echo and A-Fib observered in a Holter monitor [1]

I've been heavy for a long time despite doing a lot of exercise and the one thing that worked for losing weight before Zepbound was that time I (1) had something like a manic episode and during that (2) discovered the weird pain that had been moving between my upper back, shoulders and neck for decades was really caused by trouble with my TMJ and had six months where I just threw random foods (let's say pork loin, seaweed, carrots and turnip, it was a running gag to put together the strangest combinations I could) into a pot and blend them with an immersion blender before cooking... and it cleared up.

My nutritionist now who is supervising my weight loss is pretty happy that I'm an exerciser but I haven't been doing quite as I'd like lately because I hurt my leg practicing theranthropy [2] and have had to pace myself, like developing isolated kettlebell exercises I can do at home that work my upper body without loading my quads though I am getting better and probably could start doing more whole-body stuff.

[1] ... which I don't quite believe, once I got into biofeedback I learned how to read two-lead EKGs and I can't really make out the P-wave a lot of the time and I don't think 10 bad heartbeats out of 10^6 evaled by a computer means anything

[2] ... if you gotta know I "go out-as-a-fox" to charm people to do street photography and part of that is "walking like an animal" while carrying a heavy loadout of equipment and learning to do that without putting too much stress on my body, it didn't help at all that I tried a pair of New Balance 1080's which were the worst shoes I've ever tried, like they caused more trouble than the high-heel boots I've worn going out in drag for halloween.
