Before beginning the circuit, warm up with dynamic stretching and mobility exercises for the shoulders, hips, and ankles. During chest-to-bar pull-ups, focus on engaging the back muscles and pulling the chest towards the bar. If chest-to-bar pull-ups are too challenging, modify with regular pull-ups or assisted pull-ups. In hang power snatches, use a weight that allows for good form throughout the set. Focus on keeping the barbell close to the body and using the hips to generate power. During jumping air squats, focus on maintaining good form and landing softly. If jumping is too challenging, modify with regular air squats or a different lower body exercise. This circuit is designed to challenge your strength and endurance. Pace yourself throughout the 22 minutes and focus on maintaining proper technique. Finish with a cooldown involving stretching, particularly focusing on the shoulders, hips, and legs.
