I broke a rib while grappling. Full of adrenaline, I trained for 30 minutes after that, explosivly, because I thought I was just bruised. Doc diagnosed me, told me to take it easy for 6 weeks and told me it's a slow healing process and that pain will dictate what I do forward.
I am not going back to grappling until it's fully healed, and I'm not doing anything that will interfere with my healing. I asked him if could train my upper body, eventually, and he just repeated that I could do anything that didn't hurt.
What's your experience training with a broken rib? If it means 6 weeks on the leg extention machine, so be it. I could do with some light weight training and hypertrophy anyway. First week is off anything anyway.
