A planche (from French "planche", meaning "plank") is a skill in gymnastics and calisthenics in which the body is held parallel to the ground, while being supported above the floor by straight arms.
Depending on the event, it can range from a A to a D skill, and must be held for at least two seconds.
The main muscles used in this exercise are the anterior deltoid and the biceps, but the abdominals, chest, shoulders, lower back, and glutes also play important roles.
[2] As the planche is a demanding position, athletes train for it with a progression of simpler moves, advancing to the next when they have gained mastery of the intermediate positions.
The arms should be locked at all times in all positions, except frog stand.
