Well, Alfred if you're randomly joining forums to talk about exercise, you picked the wrong forum. But if you want to know how much time I spent BEFORE I got ME/CFS, 1 hour 3 or 4 times a week including aerobics/functional fitness, weight training, core work/pushups, balance work and stretching. For a while there, I was rollerblading a lot. Those were the days!
Now--stretching only, every other day. I plan to incorporate a little core work and weight training back in, maybe, if it doesn't tire me out.
