Sorry to hear of your broken rib. Yes, it seems harder to me to keep in shape and I'm quicker to decline after not exercising - but ribs don't tolerate movement as they knit, and they can be the biggest pain while healing. I had a foot operation which kept me off for four weeks and it really was depressing not being able to do anything at all... I hope you keep your spirits up during the process. We're rooting for you!
