Toto, no I had no problems with imbalances. With having my left out of commission, my biggest concern was not losing strength in the good arm.
After talking with my doc for a while, he decided to let me handle my rehab on my own. I didn’t follow a routine, but I can give you an idea of what I did from my log entries. Basically a bunch of machine stuff and trying to very gingerly moving my left arm without causing pain, but get it moving
Tuesday June 17 I had my surgery on my left shoulder.
Saturday June 21 was my first day in the gym. I did the following:
hammer strength bench press
right arm - 1plx10x3
seated Chest supported row
right arm - 2plx10x2, 2pl/25x10x2
left arm - no weightx8x3
hammer strength pulldown
right arm - 50x10, 75x10
pushdowns with D handle
right arm - 50x10x3
left arm - 20x10x2
Did pretty much the same workout again on that Tuesday (7 days post surgery), then nothing till Sunday and squatted with the safety squat bar up to 3 plates and then shut it down. I lifted conservatively, but also not being a pussy.
2 weeks and a day after my surgery is the day the Dr told me I could resume training, but anything that put pressure on my shoulder (pretty much everything haha) had to be at 25% for 10 days increasing every 10 days.
That is what I did, but like that other dude said we probably had different surgeries - I’m no Dr I just play one on tv. Take it slow and easy, and if you don’t like what the doc tells you get a second opinion also.
