The planche is an advanced bodyweight exercise that requires significant strength and balance. To perform a planche, start in a push-up position with your hands placed shoulder-width apart. Engage your core and lean forward, lifting your feet off the ground while keeping your body parallel to the floor. Your arms should remain straight throughout the movement. Hold the position for as long as possible, maintaining a straight line from head to toe. This exercise demands strong shoulders, core, and wrists.
