I use 75% machines, 25% free weights.  I can do pretty good weight on every body part except bench press.  For example I workout with 150 on bicep machine, 200 on fly deck, 300 on shrug machine, etc.  However I can only do 150 on the bench.  I do 3 to 4 sets of 10.  If I drop sets and reps I still can't go much past 150.  Why am I so weak in that exercise???????????????
