Begin with a warm-up focusing on cardio preparation and dynamic stretches for full-body mobility. Start the workout with a Buy-In of a 1,900 meter Run, pacing yourself to conserve energy for the subsequent exercises. Transition into 10 rounds of 12 Pull-Ups, focusing on full range of motion and a strong grip. Scale to banded pull-ups or ring rows if necessary. Continue with 12 Push-Ups, ensuring a straight body line and full elbow extension. Scale to knee push-ups if needed. Proceed to 50 Air Squats, focusing on depth and an upright chest. Follow with 20 Sit-Ups, ensuring a full range of motion to effectively engage your core. After completing the 10 rounds, finish with a Buy-Out of a 1,900 meter Run. Post-workout, engage in a cool-down with light stretching and mobility work, focusing on areas most used during the workout. The goal is to manage endurance and pacing, maintaining consistent form and intensity throughout the workout, including both runs.
