Handstand push-up
The handstand push-up - also called the vertical push-up or the inverted push-up, also called "commandos" - is a type of push-up exercise where the body is positioned in a handstand. For a true handstand, the exercise is performed free-standing, held in the air. The Handstand Push Up is an advanced bodyweight exercise that is highly effective for hypertrophy and explosive strength, particularly in the shoulders, arms, and triceps. To prepare the strength until one has built adequate balance, the feet are often placed against a wall, held by a partner, or secured in some other way from falling. Handstand pushups require significant strength, as well as balance and control if performed free-standing.
