For Officer Nathan Martin's workout, set a 20-minute timer for the AMRAP. Begin with 6 box jumps, ensuring you achieve full hip extension at the top of each jump. Focus on landing softly to prepare for the next rep.

Next, transition to 4 bar muscle-ups. Use a false grip for better control and engage your core for an efficient transition from the pull-up to the dip position.

After completing the muscle-ups, perform 74 double-unders. Keep your elbows tucked close to your body and use your wrists to facilitate the rotation of the jump rope.

Finish with 45 wall ball shots, aiming for a target at least 9 feet high. Maintain a strong squat position, and use your legs to generate power for the throw.

Scale the box jumps by reducing the height or swapping to step-ups, ensuring a safe and effective movement. For the bar muscle-ups, beginners can use bands for assistance or substitute with ring rows to build strength. Adjust the double-unders by using single skips or performing a set number of attempts before switching to basic jumps to maintain cardio engagement.

For the wall ball shots, reduce the weight of the ball to 6–10 lbs (2.7–4.5 kg) or lower the target height to accommodate your current fitness level. Consider reducing the total number of rounds to make the workout more manageable, aiming for 12–16 minutes as a target time to complete your scaled version.

Your score for the Officer Nathan Martin workout, which is an AMRAP of 20 minutes, is calculated by counting the total number of full rounds completed, along with any additional reps completed after your last full round.

In this workout, you will perform 6 Box Jumps, 4 Bar Muscle-Ups, 74 Double-Unders, and 45 Wall Ball Shots in each round. Keep track of the number of times you complete this sequence within the 20-minute time frame.

For instance, if you complete 5 full rounds and finish an additional 2 Box Jumps and 1 Bar Muscle-Up, your score would be 5 rounds + 2 Box Jumps + 1 Bar Muscle-Up, equating to a total score of 5 + 2 + 1 = 8 reps in total beyond the rounds.

Begin at a manageable pace to avoid burnout. For the box jumps, focus on landing softly to reduce impact and maintain form. Break the bar muscle-ups into sets if needed, ensuring each rep is clean and controlled. Utilize double-unders to build momentum; if you struggle, switch to single-unders to conserve energy.

When tackling wall ball shots, aim for an appropriate weight that allows consistent movement without sacrificing form. Keep a steady rhythm, and use your legs to engage the core effectively. Stay disciplined with transitions, aiming to minimize rest between exercises.

Monitor your heart rate and adjust as necessary to keep a sustainable effort throughout the 20-minute workout. Consistency is key to maximizing your score.

Intermediate: 5–7 rounds. Advanced: 8–10 rounds. Elite: 11+ rounds. Achieving over 200 total reps indicates exceptional endurance and efficiency in the workout.

The combination of box jumps, bar muscle-ups, double-unders, and wall ball shots requires a well-rounded fitness level, as each movement engages different muscle groups and energy systems.

Striving for consistent pacing throughout the 20-minute AMRAP is essential for maximizing rounds and achieving a competitive score.
