My training while on is the same as it was when I was off.
I have found what works for me and what doesn't work for me. Some exercises only work if I do 10-15 reps... some only produce results if I do 4-6 reps.
If I had to sum it up, I would say semi heavy, intense, moderate number of sets...
though I have done volume training in the past (I mean REAL volume training) and gotten nice results from that as well.
