So I am going to switch my workout routine from semi isolation to upper and lower body workouts. Two upper body days into lower body days. I've never practiced the De loading as in less volume for a few weeks . Instead I would just take a few days off of the gym every three or four weeks. So my question is how many weeks should I go all out and how many weeks should I decrease the volume 4D loading phase and can anyone recommend a good upper and lower body workout
