Begin the workout by performing max unbroken ruck push-ups. Ensure you have a sturdy ruck on your back, maintaining a straight line from head to heels. Focus on proper form, lowering your chest to just above the ground on each rep. Rest as needed to maximize your output but aim to complete as many unbroken reps as possible.

After completing the push-ups, switch to ruck lunges. Keep the ruck secured and step forward into a lunge, ensuring your front knee stays aligned over your ankle. Alternate legs with each rep, engaging your core for stability. Complete a total of 74 lunges, aiming to maintain a steady pace while keeping your form intact. Prioritize control and endurance to finish this round efficiently.

For the push-ups, consider performing them on your knees or elevating your hands on a sturdy surface to reduce the intensity. Aim for 10 unbroken reps and adjust as necessary to maintain form.

For the ruck lunges, you can either decrease the weight of your ruck to around 10–15 lbs or perform them without a ruck. You can also modify the movement to reverse lunges if that feels more comfortable.

If the full 8 rounds feel excessive, reduce the total rounds to 6 and maintain focus on form and execution. Tracking your progress is essential, so note your modifications and aim to increase repetitions or weight as you improve.

Your score for the Stirling benchmark workout is calculated by combining the total number of full rounds completed with any additional repetitions performed after your last full round.

In this workout, you will complete rounds consisting of max unbroken ruck push-ups followed by 74 ruck lunges. For example, if you finish 5 full rounds and then complete an additional 20 push-ups in the final round, your score would be 5 rounds + 20 push-ups, which totals 5 + 20 = 25 reps overall.

Ensure you accurately count every rep, as this contributes to your final score. The goal is to push your limits while maintaining proper form throughout the workout.

Approach the 8 Rounds for Time with a strategic mindset. Start with a steady pace during the initial rounds to prevent early fatigue. Prioritize efficient transitions between exercises to maximize your overall time.

When performing the ruck push-ups, focus on maintaining a tight core and proper form to prevent injury. If you find yourself struggling, consider breaking them into manageable sets instead of pushing for maximum reps. For the ruck lunges, engage your legs and core to maintain stability throughout the movement.

Stay mindful of your breathing; controlled breaths can enhance endurance. Use a steady rhythm to keep your heart rate manageable and maintain focus. Finally, remember to hydrate before and after your workout for optimal recovery.
