I need a good way of knowing how to feel overtrainging DURING a workout. It would be great to know. I do about 12 - 15 sets per workout and do one bodypart per workout, each body part per week, working out about 5 days a week. What is the best split for massing. Many say its a Chest-Tris, Back-Bis, rest, Legs, rest, shoulders -->. Is it feasible to do all arms on one day, chest and abs, rest, legs, back and shoulders, rest --> repeat. I fear overtraining like the plague. Mainly cause I dont know if Im doing it.
