Begin with a thorough warm-up, including dynamic stretching and mobility exercises for the hamstrings, glutes, and lower back. For deadlifts, use a weight that allows for good form and technique throughout the set. If 225/155 lbs is too heavy, reduce the weight to maintain proper form and safety. In box jumps, focus on landing softly and with control. If 24/20 inches is too high, reduce the height to maintain proper technique and safety. For double-unders, aim for a consistent pace and rhythm. If double-unders are too challenging, modify with single-unders or jumping jacks to maintain the workout's stimulus. This workout is a high-intensity test of strength and cardiovascular endurance. Pace yourself across the rounds and exercises, and finish with a cooldown involving stretching, particularly focusing on the lower body and back.
