I've been going between 9-10 pm but I thinks thats too late but at the same time I have so much energy at that time.I think its too late because I have to eat not long after exercising but than I can't sleep shortly after eating so I end up sleeping too late. So when is the best time to exercise? I've heard buddhists say its either at sunrise or dawn because you're body is n'sync with the energy of the sun..or something like that, and indeed the gym is most full at around 4-5pm, so is that the best time?
