Begin with a thorough warm-up, including dynamic stretching and mobility exercises for the upper body, lower body, and core. For strict pull-ups, aim for a full range of motion and maintain good form throughout the set. If you're unable to do strict pull-ups, modify with assisted pull-ups using a band or perform ring rows. In deadlifts, use a weight that allows for good form and technique. If 275/185 lbs is too heavy, reduce the weight to maintain proper form and safety. For burpees, maintain a consistent pace and focus on good form, including a full extension at the top of the movement. In double-unders, aim for a smooth and consistent rhythm. If double-unders are too challenging, modify with single-unders or jumping jacks. For the 100-meter run, maintain a steady pace and focus on good form, including proper foot strike and arm swing. This workout is a high-intensity test of strength and endurance. Pace yourself throughout the rounds and focus on maintaining good form and technique. Finish with a cooldown involving stretching, particularly focusing on the legs, back, and shoulders.
