Begin with a thorough warm-up targeting your legs, core, and upper body. For the weighted run, choose a weight that is challenging but allows for proper form and pace yourself to maintain a steady speed throughout the run. Push-ups require good form and technique. Focus on engaging your core and keeping your body in a straight line. If push-ups are too challenging, modify with knee push-ups or wall push-ups. Kettlebell swings require explosive power and good form. Choose a weight that is challenging but allows for proper form. If you don't have access to a kettlebell, substitute with dumbbell swings or resistance band swings. Box jumps require good form and technique. Choose a height that is challenging but allows for proper form. If box jumps are too challenging, modify with step-ups or squat jumps. This workout is a test of endurance and strength. Focus on maintaining a steady pace and prioritize form and safety. The weighted runs serve as a buy-in and cash-out to the rounds of exercises. Cool down with stretching and light cardio to aid recovery.
