I know that free weights are preferable so don't flame me for asking this question. Unfortunately, due to a recent shoulder injury, I'm in the process of building my bench up to what it use to be. I was thinking that using the chest press machine to do a few sets (i.e. 3-5 rep max) with a very heavy setting would somewhat make up for my inability to go heavy on bench at the present. Obviously its not going to work the supporting muscles and when I can bench heavy again I will, I'm just wondering if it would add any benefit (i.e.: some strength/size) or if I should just leave it out)?
