Workout Description

Why This Workout Is Medium

This AMRAP features light loading (6kg wall balls) and fundamental movements, but the escalating rep scheme creates significant volume accumulation. The work-to-rest ratio is continuous with no built-in recovery, and the combination of wall balls and burpees creates moderate cardiovascular and muscular fatigue. Most average CrossFitters complete this as prescribed, though fatigue compounds noticeably in later rounds. The 12-minute window prevents extreme volume, keeping it manageable rather than brutal.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Escalating rep scheme (5-10-15-20...) demands progressive muscular endurance. Athletes must sustain output across multiple rounds with accumulating fatigue and volume.
• Endurance (7/10): 12-minute AMRAP with escalating volume creates sustained cardiovascular demand. Continuous movement with minimal rest periods challenges aerobic capacity throughout the duration.
• Speed (7/10): AMRAP format incentivizes rapid movement cycling and minimal transitions. Athletes must balance speed with sustainability across escalating rep counts.
• Power (6/10): Wall balls and burpees are inherently explosive movements. Maintaining power output across rounds becomes increasingly difficult as fatigue accumulates.
• Flexibility (3/10): Wall balls demand shoulder mobility and hip extension. Burpees require basic spinal flexion and shoulder range, but demands remain moderate overall.
• Strength (2/10): Light 6kg wall balls and bodyweight burpees require minimal force production. Workout emphasizes muscular endurance over maximal strength development.

Movements

• Wall Ball
• Burpee

Scaling Options

Wall ball weight: reduce to 4kg for newer athletes or those with limited squat depth. Movement substitution: replace wall balls with goblet squats (light KB) if a wall ball target is unavailable, or air squats for beginners. For burpees, scale to step-back burpees (step feet back and forward instead of jumping) to reduce impact and slow the heart rate spike. Volume modification: cap the rep increase at 5 reps per movement per round (as written) but consider starting at 3 reps each instead of 5 if the athlete is newer, making rounds 3, 6, 9, 12 reps. Time can remain at 12 minutes for all levels.

Scaling Explanation

Scale if you cannot perform at least 10 unbroken wall balls at the prescribed weight with good depth and a stable overhead position, or if burpees cause you to stop completely and rest for more than 10-15 seconds at a time. The goal is to keep moving — even slowly — for the full 12 minutes. Prioritize movement quality over speed: a shallow wall ball squat or a sloppy burpee with a rounded back is not worth the extra rep. Athletes should aim to complete at least 4 full rounds (reaching the round of 20 reps). If you're finishing round 2 (10 reps) already gassed, the load or movement is too demanding — scale immediately.

Intended Stimulus

This is a moderate time domain workout (12 minutes) with a sneaky twist — the escalating rep scheme turns what starts as a sprint into a grinding mental and conditioning battle. Early rounds feel easy and fast, but by rounds 3-4 (15-20 reps each) the cumulative fatigue hits hard. The primary challenge is pacing discipline and mental toughness as the volume compounds. Energy demand is a sustained hard effort — not a flat-out sprint, but never truly comfortable. Expect your lungs and legs to be on fire by the midpoint.

Coach Insight

The biggest mistake athletes make here is going out too hot in rounds 1 and 2 (5 and 10 reps) — those feel almost too easy, which tempts you to sprint. Resist that urge. Treat the first two rounds as a warm-up and settle into a rhythm you can sustain into the 15s and 20s. For wall balls, keep your chest tall, use your hips to drive the ball, and breathe on the way down. For burpees, find a steady, consistent pace — a slow burpee you can maintain beats a fast burpee that forces a rest. By the round of 20 (round 4), consider breaking wall balls into two sets (12+8 or 10+10) before you feel like you need to. Transitions between movements should be immediate — no standing around. Track your rounds clearly so you know exactly where you are in the rep scheme.

Benchmark Notes

This ascending-rep AMRAP gets exponentially harder each round — round 1 is 10 reps, round 2 is 20, round 3 is 30, etc. The primary limiters are burpee endurance and wall ball conditioning under accumulating fatigue. L5 (~3.3 rounds, meaning into round 4 with ~30 reps done) reflects a solid intermediate athlete managing the steep rep climb with brief breaks.

Modality Profile

Wall Ball is a weighted movement (external load with medicine ball), classified as Weightlifting. Burpee is a bodyweight movement, classified as Gymnastics. Two movements split evenly: 50% W, 50% G.
