Workout Description

Why This Workout Is Medium

This AMRAP features bodyweight movements (wall balls and burpees) with escalating volume, creating moderate fatigue accumulation over 12 minutes. The rep scheme starts manageable (5+5) but grows progressively (10+10, 15+15, etc.), forcing athletes to work through increasing fatigue. Most average CrossFitters will complete 3-4 rounds. The continuous nature prevents built-in recovery, but the movements don't heavily interfere with each other. Limiting factors are cardiovascular capacity and leg endurance rather than skill or heavy loading.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Escalating rep scheme (5-10-15-20...) accumulates significant volume quickly. Wall balls and burpees demand repeated muscular effort, testing ability to sustain output as fatigue accumulates across rounds.
• Endurance (7/10): 12-minute AMRAP with escalating volume creates sustained cardiovascular demand. Continuous movement with minimal rest forces aerobic system to work throughout, though shorter duration prevents pure endurance classification.
• Speed (7/10): AMRAP format incentivizes fast cycling and minimal transitions. Athletes must maintain quick movement pace and efficient transitions between movements to maximize rounds within 12 minutes.
• Power (6/10): Wall balls are inherently explosive, requiring rapid hip extension and upper body power. Burpees contain explosive components (jump), though fatigue reduces power output as rounds progress.
• Flexibility (3/10): Wall balls require shoulder mobility and hip extension. Burpees demand full-body range of motion including chest-to-deck position, but demands remain moderate compared to extreme mobility movements.
• Strength (2/10): Wall balls use moderate loads and burpees rely on bodyweight. Neither movement emphasizes maximal force production; focus is muscular endurance rather than strength development.

Movements

• Wall Ball
• Burpee

Scaling Options

Wall ball weight: scale to 14 lb (women Rx) or 10 lb for newer athletes; reduce target height to 9 ft if needed. Wall ball substitution: dumbbell goblet squat to press or air squats if no wall ball is available. Burpee modifications: step-up burpees (step feet back and forward instead of jumping), no-push-up burpees (remove the chest-to-floor component), or box step-overs as a full substitution. Volume modification: cap the rep increase at 5 reps per movement per round (as written) but consider starting at 3 reps each and adding 3 per round for deconditioned athletes. Time adjustment: reduce to a 9-minute AMRAP if the athlete struggles with sustained output.

Scaling Explanation

Scale if you cannot perform at least 10 unbroken wall balls at Rx weight with good depth and hip drive, or if burpees take longer than 1 second per rep in early rounds. The goal is to keep moving — if you are standing and staring at the wall ball by round 2, the load or movement is too demanding. Prioritize intensity and continuous movement over Rx weight. Technique is especially important on wall balls (squat depth and lumbar position) and burpees (plank integrity) — if form breaks down significantly, scale the load or movement before scaling the time. A well-scaled athlete should complete at least 3 full rounds and feel genuinely gassed by the end.

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 almost deceptive, but by rounds 3-4 the cumulative volume becomes significant. Expect a hard sustained effort that taxes your aerobic engine, legs, and lungs simultaneously. The primary challenge is mental: managing the growing rep counts while maintaining composure and movement quality as fatigue compounds.

Coach Insight

The biggest mistake athletes make is going out too hot in round 1 (5+5) and round 2 (10+10) — these feel trivial, but you are banking fatigue for later. Treat the first two rounds as a warm-up and move at a conversational pace. By round 3 (15+15) and round 4 (20+20), you will feel the shift — this is where the real workout begins. For wall balls, keep your chest tall, use your hips to drive the ball, and breathe on the way down. Break wall balls before you hit failure — in round 3+, consider sets of 8-7 or 10-5 rather than grinding through unbroken. For burpees, find a sustainable rhythm: step up instead of jumping up if needed, and keep your hips from sagging in the plank position. Transitions between movements should be immediate — do not rest between wall balls and burpees, let the movement change serve as your recovery. Most athletes will complete 3 full rounds (60 wall balls + 60 burpees) and get partway into round 4. If you finish round 4 cleanly, you had a great day.

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 capacity under fatigue and wall ball breathing. L5 finishes round 3 and gets partway into round 4 (~3.3 rounds = completing round 3 plus ~18 reps into round 4), as the cumulative rep demand (60 reps through round 3) is substantial for a median CrossFitter in 12 minutes.

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.
