I've been planning on running a Dbol/test/deca stack for about three months and all of a sudden I had to have surgery on my right hand and the doc said no upper body weight training for 2-3 months. Is it worth still running the juice and just train my legs, abs and core? My lower body is smaller than my upper body. And if I did how many times a week could I train my lower body without overtraining?
The answer to your question depends largely on your goals.
Even if I couldn't do bench press, I would only have one deadlift and one squat session/week. Anything more would be counterproductive for me.
You allowed to do anything that doesn't involve your right hand? So that you can still do abs, 45 degree hypers, GHR, etc?
Can you still lift with the left hand? I have broken my right hand a couple of times and trained just my left side, I have read studies that say there is a carry over.
It is far from ideal, but better than nothing.
As far as the stack, I personally ran 500mg of test while I was injured just to try and hold on to my mass while training was impaired. IMO there is no point going on a proper stack and trying to gain, save it untill your 100%.
