Start this 20-minute circuit with a strategy to maximize efficiency and endurance. Initiate with a dynamic warm-up emphasizing mobility for the shoulders, hips, and ankles, plus a cardiovascular component to elevate your heart rate—think leg swings, arm circles, jump rope, and a light jog. For the ground-to-overheads, prioritize form and efficiency, breaking the reps into manageable sets if needed. Choose a technique (snatch or clean and jerk) that you're most comfortable with to execute the lifts safely and effectively. The wall ball shots require a steady pace; aim to minimize breaks by breaking the set into manageable chunks. For the double-unders, maintain a relaxed posture and use wrist action for the rope to conserve energy. If double-unders are not within your skill set, perform single-unders with a 2:1 ratio as a modification. The weighted run should be approached with a focus on maintaining a consistent pace that allows you to keep moving without overtaxing your grip or shoulders. Use a weight that is challenging yet allows for completion of the 200 meters without stopping. Cool down with stretches focusing on the shoulders, calves, quads, and hamstrings. This circuit is designed to test and improve your cardiovascular endurance, strength, and skill across a varied range of movements, emphasizing the importance of pacing and efficient movement transitions.
