i recently went thru some rib & chest tear injury a few weeks ago, some newby walk ins flopped on me in a scarf hold position actually two overweight guys , i continued to roll but it got worse , i dont think any ribs were broken , i didnt see any bruises or nothing but alot of pain , then when lifting weights i thought i was ok to bench press i did ok , then the following week while benching my chest on one side hurt bad , so it that point i guess i got the chest tear again ...now im feeling better , rolled lightly and took a week off training , been taking a coral calcium supplement with magnesium and vitamin d .
