Begin with a warm-up focusing on cardio preparation and full-body mobility. Start the workout with the 2,200 meter run at a steady, manageable pace, conserving energy for the exercises ahead. For squat cleans, use a weight that allows for good form yet is challenging. If 135/95 lbs is too heavy, scale down to maintain proper technique. If you don't have a barbell, substitute it with dumbbell squat cleans. In GHD sit-ups, focus on controlled movements. If a GHD machine isn't available, modify with standard sit-ups or V-ups for a similar core workout. For double-unders, maintain a relaxed and rhythmic jump. If double-unders are challenging, substitute with twice the number of single-unders. The cash-out of 75 bar facing burpees will test your endurance. Maintain a steady pace, and modify to regular burpees if needed. This workout is a test of both endurance and strength. Focus on pacing yourself and maintaining good form throughout. After completing, cool down with light cardio and full-body stretching.
