Have you tried limiting aerobic stuff? (not saying to avoid it completely)
Running has always made me feel like I’m dying, but sprinting for a really short time feels amazing.
Also have you tried strength training? I think it feels pretty good, especially isolation exercises that don’t get my heartrate too high. I still feel tired for a few hours afterwards, but it does make me feel better overall.
Fair enough.
Personally, it only feels good if I’m not tired. Also I find lifting heavy to feel not great, but light weight and slow movements to feel good. I guess it’s a type of pain, but I think the type of soreness you get can be pretty satisfying.
Also I really think climbing is the best workout– it’s engaging and fun enough that you’re not focusing the exercise. I also loved climbing trees as a kid and a while ago I went to a bouldering gym a bit. The only downsides are that it’s a bit expensive and you can easily fuck up your hands/fingers with certain techniques.
