If you are giving each body part a full seven days between direct workouts why limit the number of sets per body part? Isn't the goal to completely destroy the muscle group you are working?
I currently do about 8-9 sets per muscle group with exception of legs which I do
Leg Extentions 3 working sets
Leg Curls - 3 working sets
Squats - 6 working sets
Lunges - 4 working stes
Calf Raises - 5 working sets
I usually do 12 sets on chest (various presses and flys)
9 on bis
9 on tris
9 on shoulders
12 or more on abs (one day a week)
12 on back (includes dead lifts)
8 on traps
I'm making good gains but my friggen workouts take forever.
Thing is, if I don't hit these number of sets I don't usually have the soreness the following two days that I do if I go with less volume. Every Set is done to Positive failure and consist of 4 to 6 reps. I rest two minutes between each set. Thinking about dropping that to 60-90 seconds.
I'm not to convinced of the high rep routines but I'm thinking of taking the reps to 8 per set.
I don't do cardio. I effing hate cardio. Unless,of course, sex qualifies as cardio.
Now all I need to do is get my diet set. That is the hardest friggen part. Figures it is about 70% of the equation.
