Begin with a dynamic warm-up, including exercises such as jumping jacks, high knees, and lunges to get your heart rate up and muscles warmed up. During the 1-mile run, maintain a steady pace that allows you to complete the distance without stopping. If running is challenging, consider walking or jogging at a slower pace. For hand release push-ups, ensure that your chest touches the ground before releasing your hands. If these are too challenging, modify with regular push-ups or knee push-ups. In air squats, focus on maintaining proper form, keeping your knees in line with your toes and your weight in your heels. If these are too challenging, reduce the reps or modify with assisted squats using a chair or wall. For pull-ups, aim for a full range of motion, pulling your chin over the bar. If these are too challenging, modify with assisted pull-ups using a band or perform jumping pull-ups. This workout is designed to challenge your endurance and strength. Pace yourself throughout the circuit, taking breaks as needed to maintain proper form and avoid injury. After completing the circuit, finish with a cooldown involving stretching, particularly focusing on the legs, back, and shoulders.
