Begin with a dynamic warm-up to prepare your body for the workout. Focus on activating your core, upper body, and leg muscles. For air squats, maintain proper form throughout the set, ensuring your knees track over your toes and your hips reach below parallel. In push-ups, aim for a full range of motion, lowering your chest to the ground and fully extending your arms at the top of the movement. For sit-ups, maintain a consistent pace and ensure full range of motion, touching your hands to the ground behind your head and reaching forward to touch your toes. In pull-ups, aim for a full range of motion, ensuring your chin clears the bar at the top of the movement. Modify with assisted pull-ups or jumping pull-ups if necessary. This workout is a test of endurance, so pace yourself and aim for consistent effort across all five rounds. Finish with a cooldown involving stretching, particularly focusing on the legs, chest, and back.
