Really love this chest workout! I've been doing a whole variety of pushups to workout my chest (ie Military, Ultra-Wide, Decline, Diamond. . . ) and have noticed little changes in the past year or so.  A day later after this workout and my chest is exploding with pain from all the new squeezing type of dumbbell exercises! I do have one issue which I would like some feedback on, and it's that I have very small wrists and even with good form I find that 3/4 through this workout I feel joint pain. . .

I get into my starting position of each exercise using my wrist muscles to lift the dumbbells into the air above me.  Without a self-spotting rig, it seemed the only way to do all these sets, yet now I find I may just have to set one up if my wrists constantly get worn out before my chest does. . . 

btw, I lift 30 Ib for dumbbell press, and lifting 25 Ib for flies. 

my hands used to hurt while doing flys, but i think i was holding the bar too hard.

i dont think you breath right. . .  thats a serious mistake . .

So I would say it worked
