The Bent Arm Planche is an advanced isometric exercise that requires significant upper body and core strength. Begin by placing your hands shoulder-width apart on the floor. Lean forward, bending your elbows to lower your body while keeping your feet off the ground. Your body should be parallel to the floor, supported by your bent arms. Engage your core and maintain a straight line from your head to your toes. Hold this position, focusing on balance and control.
