I was reading Jason_Ferruggia's article that was posted on Ironmagazine's homepage, and read that he felt the pec dec machine to be dangerous and worthless for gaining muscle. I hurt my shoulder a while back (tore one of the muscles) and have not been able to do flys since. Because I cant do flys, I started using the pec dec as a substitute and started to really like the machine after benching. Am I wasting my time or does anyone else like using the pec dec?
