I have been working out really hard over the past 14 months and have went from 140 lbs to 195 lbs by only taking creatine, eating right, and protein. I recently tore my left rotator cuff and am really pist off about it because I can't lift **** with my left arm now. What can I do to keep from losing what I have gained? The doctor says I will need at least 6 weeks of no lifting if not 10. Somebody help me!
