"Learn How to Do Different Types of Push-ups Exercises!
Whether you're a push-up pro or novice, there's something here for you.
Push-ups are pretty damn hard. The pushup may just be the perfect exercise that builds both upper body and core strength.
Done properly, it is a compound exercise that uses muscles in the chest, shoulders, triceps, back, abs, and even the legs.
It has many modifications so beginners can start with easier versions and work up to the standard pushup, while you can find a challenging variation if you are advanced. You can do the pushup as part of a bodyweight exercise session, a circuit training workout, or a strength workout."
