Maybe I am non-normal here, but I've no idea what that feels like. Mind, I've run a marathon before, participated in a few organized athletic sports leauges, been on sports teams, improved my weight lifting substantially, and just gone for mile runs and bit of basketball.
I've never felt like I needed to go out and exercise. Sitting on the couch has always been just fine.
It has always been an internal battle to go out and exercise. I feel like crap after exercising. I'm tired, sweaty, grouchy, my legs are wobbly after any distance run, and it takes about 3 hours for me to wind down. I do sleep better, but I can't exercise after ~6pm if I want to get to sleep by ~10pm. My concentration is shot during the winding down and I can't work or study either. Truely, honestly, I do not like exercising. Like, I know it's good for me, but, man alive, it just sucks to do!
Look, I know I am weird here, but based off the data on rates of exercise, I'm not super certain that I'm too far off the average.
