Pulleys:
-Rope pushdowns, hands wide apart at the bottom. Also do some sets of just the bottom 1/2 ROM.
-One-arm pulley crossovers - with the right hand hold the handle in front of the left shoulder, then extend the arm bringing the handle across the chest to the other shoulder.
-One-arm pulley, standing with back to the pulley - with the right hand hold the handle around the left waist, then cross the pulley out in an arc in front of you to the other side of the stomach.
-Close-grip E-Z curl or triceps bar bench press lowered down to the thoat, esp. on a slight incline, and especially the top 1/2 ROM.
-California/JM Press: Lower an E-Z curl or triceps bar to the face (carefully), then slide the weight to chest and bench press it back up, repeat.
-Close-grip pushups with hands in the "diamond" position with the fingers touching and palms further part. Especially with feet elevated.
-Dips/dip machine with knuckles facing in.
Dumbells:
-Elbows wide apart lying or seated extensions. Keep the elbows wide and lower the DBs around your ears (lying) and in front of your face (seated/incline).
Pumpster gives great advices here. I'd like to touch on one of these excersises I actually uses myself, slightly modified.
I do this excersise, except with the rope from the low pulley, and with my back towards the pulley. It's a french press, but using a rope.
Reason for doing it only the bottom part, is because I don't work that ROM when doing benchpressing, board work and close grips.
It's the only additional excersise I use, and I stick with moderate or light weights, avoiding injury to the elbow. Saving the heavy work for the main benchpressing.
As I stated, good advices IMO.
