Ive just been reading and hearing so many conflicting opinions on this topic i would really like some of the forum vets to clear this up for me. So the general consensus (for most) seems to be that off cycle or natural aim for 12 sets per workout on the larger muscles and 8 on the smaller ones hitting each muscle once a week. But what about on the juice? Does the muscles ability to repair itself far quicker on cycle allow us to hit each muscle group much harder with many more sets and exercises or is this just a waste of time that will lead to overtraining and injury. This is my current cycle and workout:

Weekend Rest

I aim for around 8 reps per set with a three second negative on each, every set is to failiure.

Is this too much? i often find the target muscle i have worked is sometimes in a fair bit of pain post workout (especially lower back on mon and tues), but the next morning i always feel fine so i sort of attribute it to part of the process. Anyway i would be really keen to hear your opinion on this and any editing of this training regime that you would advise.
