what hand position works the chest and the triceps?
dips WORK the chest and tri's. do you mean like wider or closer to your body?
Elbow tuck is what determines the primary muscle. Proximal to the core is for triceps and distal is for chest.
What is a good substitute for dips? I read in Chad Waterburys book decline bench?
WELL, it's more about body position. BUT, if you try it Larry Scott's ways a la Vince Gironda who invented it, with knuckles facing each other, chin on chest, body bent over with legs well out in front of you, then it's all chest. You must have V-bars to to this exercise.
Body postion for triceps is straight up and down, to hit the chest more, body can be like I mentioned above or legs crossed behind you so you get more of a forward slant.
Dips are the upper body squat, KING exercise it is.
I highly prefer dips over the bench press, especially the bar. But that is my opinion and only that.
I am so happy you caught the keyword "substitute" Rosie, I dont have a barbell, but have dumbbells which go to 130 LBS each. They are the Power Blocks and I also have an Incline\Decline bench.
Would a close grip flat DB bench press work the same muscle groups?
