Some friend of mine ripped some crap in his shoulder not too long ago lifting also. Took months to heal.
Shit I myself was on a waverunner going about 65mph while standing up last Sept. got about 3ft of air when this unsuspecting jackass in some massive boat cut across in front me on the river. Went right over this massive wake, and when I came down my right leg was slightly bent outward and it twisted the shit out of it almost fell off too. My knee still isn't right; almost healed but it’s been so long.
Careful guys very easy to hurt yourself.
