Begin with a comprehensive warm-up targeting your legs, core, and upper body. For the double-unders, focus on proper form and technique to avoid tripping or injury. If double-unders are too challenging, substitute with single-unders or jumping jacks. Pull-ups require good form and technique. If pull-ups are too challenging, modify with assisted pull-ups or ring rows. Squats require good form and technique. Focus on keeping your knees in line with your toes and engaging your glutes and core. If squats are too challenging, modify with air squats or goblet squats. The 100 meter sprint requires explosive power and speed. Focus on proper form and technique to avoid injury. Rest for 2 minutes between rounds to allow for recovery and to maintain a steady pace throughout the workout. This workout is a test of endurance and strength. Focus on maintaining a steady pace and prioritize form and safety. Cool down with stretching and light cardio to aid recovery.
