That looks a little worse than mine, but I cracked 4 ribs, too.
I started on the recumbent bike trainer at the gym after 11 days and swimming after 17 days. The swimming hurt and I didn’t overdo it; I think it helped with recovery. My doc had me doing range-of-motion exercises from the beginning, which hurt like hell but I believe helped a lot. Started easy jogging after 3.5 weeks.
I was able to jump back into my IM training plan fully after 6 weeks.
