I'll give that 4x12 a try, I might have to change up my routine a little to match. The old routine was low and heavy on compound exercises except for bench and 2x12 for smaller groups split 3 days a week.
Old routine was
day 1
squats 4x4-6
leg curl 12-15 1st set 10 2nd set
bench 1x6-8, lower weight, 1x7-9 , lower weight, 1-8x12
chest support row (can't do now, new gym doesn't have this) 9-12 1st set 10-15 2nd set
db curl 9-12 1st set 10-12 2nd set
tricep pull downs 9-12 1st set 10-12 2nd set
seated calf raises 9-12 1st set 10-12 second set
day 2
deadlifts 1x5 (warmup set light weights) 1x3, increase weight, 3x3, 4th set try to push to 5 reps
db shoulder press 9-12 1st set 10-12 second set
cg bench 9-12 1st set 10-12 second set
tricep pull downs 9-12 1st set 10-15 second set
db lateral 1x10-15
abs
day 3
dips 8-10 1st set 10-12 second set
seated cable row 9-12 1st set 10-15 second set
1 leg leg press 9-12 1st set 10-15 second set
barbell curl 9-12 1st set 10-12 second set
standing calf raise (seated now, no standing machine at new gym) 9-12 1st set 10-12 second set
I think I could probably keep all of the same lifts and just drop the weights far enough to be able to do 4x12 on everything, but would that work well on 3 days a week, or should I shuffle around some exercises to focus on single areas per day and go 4 or 5 times a week?
Thanks for the advice thus far, this is natural training, not ready to take the plunge yet, still need to get past where I was before my hiatus and come to a hard plateau. The thought nags in my mind sometimes, but it's not that I want to hit my natural potential first, it's that I'm scared that if I do go on the gear too early, I'll end up injuring myself going too far too fast and then I'll have another long break from the gym and take even longer to look the way I want. I figure about the time I've hit a solid plateau and changing shit up doesn't move me any further for a couple of months, my body will be strong enough to get stronger- or something like that
