I'm also doing bodyweight exercises, and I have been tinkering with recovery times. I can do squats 4 or 5 days in a row, then I seem to need a couple days off. For pullups (assisted) I seem to be making progress doing them one day a week. I am 47 years old with arthritis in cervical vertebrae, so my main concern is avoiding injury. I also take into account the fun stuff I do in between, a little running, biking, paddling. I just listen to my muscles and joints.
As God is my witness, I'll never be hungry again.
