I deffo have to agree with doing dips, I do them at the end of my chest session, 2 sets weighted so I can manage 8 reps on the first set, do the same weight second set and squeeze out 6 or 7. Then I drop the weight and do a further 2 sets, resting only 60 seconds between sets.

On a wide grip, keep your elbows out, head down, and knees bent in, this will make sure you stay leaning forward. If you don't, and your body starts to go vertical you will take the emphasis off the chest and onto the triceps.

Give it a try...
