Handstand push-up
Type of push-up exercise
From Wikipedia, the free encyclopedia
The handstand push-up (press-up) - also called the vertical push-up (press-up) or the inverted push-up (press-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 (HSPU) is an advanced bodyweight exercise that is highly effective for hypertrophy and explosive strength, particularly in the shoulders, arms, and triceps.[1] 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.

Similar exercises
The movement can be considered a bodyweight exercise similar to the military press, while the regular push-up is similar to the bench press.
Muscles
The primary muscles used in the handstand push-up are the anterior deltoid, middle deltoid, posterior deltoid, pectoralis major, upper trapezius, and triceps brachii.[2]
Ability
The handstand push-up is measured in the Men's Gymnastics Functional Measurement Tool (MGFMT). According to one test on competitive male gymnasts in the United States, those competing at Level 4 averaged 3.0 handstand push-ups while those at Level 10 averaged 15.7.[3]
