Perform the Pearl Harbor workout by completing 12 rounds for time. Start with 80 push-ups, ensuring full range of motion with each repetition. Maintain a steady pace, resting as needed but aiming to minimize downtime.

After the push-ups, grab a rucksack and embark on a 1-mile ruck, keeping your core engaged and walking briskly. Next, incorporate 7 sandbag clean and push presses, using your legs to help lift the sandbag overhead while maintaining a strong posture.

During the odd rounds, finish with 41 flutter kicks, focusing on engaging your core and controlling the movement. On even rounds, switch to 41 mountain climbers, ensuring that your form remains tight and your pace is consistent. Finally, conclude with another 1-mile ruck followed by the final 80 push-ups to complete the workout.

Reduce the number of push-ups to 40 if needed, breaking them into sets of 10 with rest as necessary. For the ruck, consider a lighter backpack or decrease the distance to half a mile.

Scale the sandbag weight to 20–30 pounds, or adjust the movement to a dumbbell clean and press if that feels more manageable.

For the flutter kicks and mountain climbers, cut the reps down to 21 for odd rounds and 21 for even rounds to accommodate your fitness level.

Finish strong by maintaining a 1 mile ruck but feel free to take longer rest periods or walk instead of running if necessary.

Listen to your body and focus on form to prevent injury while still getting a good workout.
