Workouts During Post-Surgery Recovery

Long story short, I have a surgery to get a fractured bone in my wrist fixed and it's a 6-12 week recovery time.

I currently work out 2 hours a day for six days a week and the longest I've ever taken a break in the past 10 years is maybe a week tops.

So I'm obviously not loving the recovery time and am trying to figure out how I could stay in shape without losing too much muscle mass. Cardio, abs and legs (minus dead lifts and possibly squats) shouldnt be an issue, but arms, chest and back are going to be a challenge without using a wrist.

I just bought some velcro straps to put on my upper forearms so I can possibly connect those to a cable machine, and I could always keep using my right arm these next two months, but I'm worried that could create a significant imbalance issue.

Wanted to see if anyone has had to deal with something similar, or if you have any ways I could get creative to stay in shape and minimalize losing too much mass.

Thanks for any insight/suggestions
