What muscles do pushups build?

Answer:
Mainly the chest, anterior deltoids (front shoulders) and triceps.Keep your body straight when doing push ups. Don't do the wormy thing.

Push ups are primarily for your chest, they also work your arms and shoulders a little. Push ups are great to burn out your muscles after a good chest routine (bench, incline bench, pec flys).

They probably will not build any muscles but instead tone the ones your already have. It works your Pectoralis Major, Anterior and Posterior Deltoids, they can work your Triceps Brachii, Trapezious, Latissmiss Dorsi, and your Rhomboids
