Gods! I used to! I had to stop the kinds of exercise I loved post disability, and the fucking physical therapy shit I can still do isn't enjoyable, it's just so damn dull and doesn't give the same feeling of satisfaction, despite hurting so much more.
But I would work out up to three hours a day when I had time. Calisthenics, strength training, martial arts (unarmed, plus various weapons), break falls and air rolls (an offshoot of the martial arts).
It was fun, and I could feel the benefits of it, and I miss the ability to tell my body what to do, and it just does it.
But yeah, I not only enjoyed the workout itself, and the benefits, but I even enjoyed the ache and burn of it. It was fulfilling on so many levels.
