I have started doing 6 days a week full body routine. On the same basis that training the muscle every day with lower intensity will result in more volume over the week. This is my 5th week into the routine and am enjoying it a lot. I was watching the Joe Rogan podcast and he has GSP trainer who was speaking about this concept and thought it was interesting to try it.
I change the rep ranges each day just to change it all up, so if I did higher reps on Squats on Mon then I will do lower reps on Tue and then medium reps on Wed and so forth. Also, I change the exercises each day as well. So may do flat bench on Mon, then incline Tue, flat dumbbell on Wed and so forth.
Mon - Chest, Back, Legs, Shoulders and Arms
Tue - Chest, Back, Legs, Shoulders and Arms
Wed - Chest, Back, Legs, Shoulders and Arms
Thur - Chest, Back, Legs, Shoulders and Arms
Fri - Chest, Back, Legs, Shoulders and Arms
Sat - Chest, Back, Legs, Shoulders and Arms
