reps can change all you want IMO
its sets and intensity that are important.

Dave, I know what your saying.

If i were to work a muscle 3 times a week it could happen several ways.

Actual considering all the DE/ME work It could happen 5 times a week if i had great recovery.

but i was refering to hypertrophy work. Also i dont have that elite level of recovery yet.

However i may start adding in extra workouts for pecs or shoulders.

What i would do is 3 sets to the breakdown of form, or two reps before total failiure, however you want to look at it. Or 1 set with rest pauses and a static hold. Each workout. That way im really doing no more than 9 sets/bodypart a week. Which is as much as or less than a volume trainer. but since i know the body completes hypertrophy and protien synthesis returns to normal within two days, and that the growth response is static, i try to take advantage of that.

My "extra workouts" would only have 3-6 sets total and would work one or two muscle groups. Probably just one to start off with. but im going to need to bring my GPP up before that happens.

This whole area of increasing recovery ability is something im a little uncertain on still. Im still digging for more info, and need practice with it.
The harder i train, the better i eat, the better my genetics seem to get
