Begin with a dynamic warm-up, including exercises that activate the core, upper body, and legs. During the 800m run, maintain a steady pace, focusing on breathing and form. For knees-to-elbows, aim for a full range of motion, bringing your knees up to touch your elbows. If this is too challenging, modify with knee raises or leg lifts. In kettlebell swings, use a weight that allows for good form and control throughout the set. Focus on using your hips to generate power and momentum. For sumo deadlift high-pulls, maintain a neutral spine and engage your glutes and hamstrings. Use a weight that allows for good form and control throughout the set. This workout is a high-intensity challenge that tests both cardiovascular endurance and muscular strength. Pace yourself throughout the rounds, and finish with a cooldown involving stretching, particularly focusing on the legs, back, and shoulders.
