Asymmetrical Push-up on Knees
This twist on a traditional push up hits deltoid and pecs and is great for beginners working to build upper body strength, or more advanced HIITers wanting to change things up. Starting in the regular push-up position with hands directly below shoulders, move one hand about six inches to the side and perform the push-up straight downward (not over the hand you moved). Track elbows back rather than outward. Repeat on the other side.
