Okay, so I have this friend of mine who is literally addicted to weight lifting. He does a full body work out, twice a day, 4-5 days a week. My friend and I have tried telling him how bad it is for his body, and he actually agrees but like I said, he's addicted. The craziest part is that he continues to make gains despite the lack of rest. He takes protein, creatine, and a mass gainer at times, but I don't think any form of supplement could counter act the lack of rest his muscles are receiving. I need some good advice and possibly some statistics that could try and make him "see the light" because I think his body will eventually fall apart.
