About 1 month ago I ruptured the distal biceps tendon in my right arm. I had surgery 3 weeks ago and have regained partial ROM of the arm. Physical therapy started last week. Due to the nature of this injury, I am severely restricted in how much weight the arm can lift until 4 months post op (approximately) which takes me out to end of August or so.
Although I'm pretty frustrated with this set back, I really want to keep working my left (good) side so that I don't have a total reversal. As such, I'm asking for advice (and I've always found the input from these forums to be excellent

) on suggestions for putting together a program where I can only use 1 -arm.
Traditionally I have mostly used free weights - barbell and dumbbells, but I'm think I may have to do more cable or machine stuff going forward. This is due not just to the injury itself, but also the need to not get overly unstable as if I lose balance and try to catch myself with the repaired arm, I'll be back to square one with a new rupture.
I'm ideally looking for a total body routine. I think I can do some lower body lunges, squats etc holding a single dumbbell, so maybe that's something to consider? I like using resistance training to get my HR up. I'm starting appreciate now how many calories I used to burn lifting weights. Specifically, my total body weight has increased from 207 lbs to 212 lbs (I'm 6'2") while simultaneously I've been losing muscle mass because I haven't done any weight training in over 1 month. As such, I know that I've packed on extra body fat beyond what the scale is telling me.

The injured arm was the dominant one, and I've really noticed a dramatic reduction in muscle mass including up to the shoulder.
Many thanks for any and all help !
