I mix it up. I use machines and free weights. While I do enjoy using free weights, the pump I get from machines is unmatched--the pump that I get from that chest press machine is not the same as I get when I use free weights.
I do like certain machines for sure, though more of a free weight person myself. 35 days now (but who's counting) with torn rotator, I've been using them (machines) more of course (have to).
I haven't been this sore in years using the machines, doing higher reps, etc. It is a good change-up. (Though I cant wait 'til this damn shoulder heals).
Been using the Hammer-Strength for chest this past month (incline, decline, flat press) and they feel good.
If I can get the gym to buy a Basile Supinator, then life as I know it will never be the same. When I showed the gym owner, he said "I have one" and pointed at the dumbbells. (Silly me).
