What does a diamond pushup work out?

Question

i'm trying to get my arms cut.

Answer 1

Triceps and your chest.....

Answer 2

I think it works out your triceps more

Answer 3

Pectorals (chest), triceps, anterior deltoids (front shoulder).

It does not work biceps.

Where it differs from a normal push up is that you put more emphasis on triceps.  Therefore it is a great tricep development exercise.

Answer 4

Pectorals, triceps, biceps and deltoids
