Workout Description
amrap 12:
5 wall balls
5 burpees
add 5 reps every round
Why This Workout Is Medium
This workout combines light, fundamental movements (wall balls and burpees) with a continuously escalating rep scheme in a 12-minute AMRAP. While the individual movements are accessible, the increasing volume creates meaningful fatigue accumulation. The average athlete will likely complete 4-5 rounds, hitting roughly 100-150 total reps. The work-to-rest ratio is continuous with no built-in recovery, but the light loading and bodyweight-based nature prevent this from becoming Hard. Most CrossFitters can sustain this intensity without scaling.
Training Focus
This workout develops the following fitness attributes:
- Stamina (8/10): High rep accumulation with escalating rounds (5-10-15-20...) creates significant muscular endurance demand. Wall balls and burpees fatigue legs, shoulders, and core cumulatively over 12 minutes.
- Endurance (7/10): 12-minute AMRAP with continuous movement demands sustained cardiovascular output. Escalating rep scheme maintains elevated heart rate throughout, testing aerobic capacity and the ability to sustain effort.
- Speed (7/10): AMRAP format demands quick movement cycling and minimal transition time between exercises. Escalating reps force athletes to maintain pace despite fatigue, emphasizing rapid rep execution.
- Power (6/10): Wall balls are inherently explosive movements requiring rapid hip extension and shoulder drive. Burpees contain explosive jump component, though fatigue reduces power output as rounds progress.
- Flexibility (4/10): Wall balls require shoulder mobility and hip extension. Burpees demand full-body range of motion including chest-to-deck position and overhead reach, moderate mobility demands.
- Strength (3/10): Wall balls and burpees rely primarily on bodyweight and moderate loads. No maximal strength component; focus is muscular endurance rather than force production.
Scaling Options
Wall balls: Reduce load to 14 lbs (men) or 10 lbs (women) if the standard 20/14 lbs causes form breakdown. Lower the target height to 9 feet if needed. Sub goblet squats or air squats if wall balls are not available. Burpees: Sub step-back/step-up burpees to reduce impact and slow the heart rate spike. Sub burpees to a box (hands on box) for athletes with shoulder or wrist limitations. Volume: If the climbing rep scheme feels overwhelming, cap the rep increase at 20 reps per movement (so rounds go 5, 10, 15, 20, 20, 20...) to keep the workout moving and avoid long stalls.
Scaling Explanation
Scale if you cannot perform at least 10 unbroken wall balls at Rx weight with good depth and a solid target hit, or if burpees take longer than 5 seconds per rep in early rounds. The goal is to keep moving for the full 12 minutes — if you're standing still for 30+ seconds at a time in the middle rounds, the load or movement is too demanding. Prioritize intensity and continuous movement over Rx weight. Athletes should aim to complete at least 4-5 rounds (reaching the 20-25 rep rounds) to get the intended stimulus. Newer athletes should not hesitate to cap the rep climb — the conditioning effect comes from sustained effort, not from grinding through 30+ rep sets.
Intended Stimulus
This is a moderate-to-long time domain grinder (12 minutes) with a sneaky twist — the reps climb every round, turning what feels like an easy start into a lung-burning accumulation challenge. The workout targets sustained aerobic conditioning with a mental toughness component. Early rounds feel deceptively manageable, but the compounding reps create a snowball effect that tests your ability to keep moving under fatigue. Primary challenge is conditioning and mental fortitude — knowing when to push and when to pace as the rep counts stack up.
Coach Insight
The biggest mistake athletes make here is going out too hot in rounds 1 and 2 (5 and 10 reps) and paying for it when rounds hit 20, 25, and 30 reps. Treat the first two rounds as a warm-up — move smoothly, not fast. For wall balls, keep your chest tall, hit full depth, and drive through the hips — don't muscle it with your arms. For burpees, find a sustainable rhythm: step back, step up is totally acceptable when fatigue sets in. Avoid collapsing to the floor — control the descent. As reps climb, break wall balls into manageable sets before you hit failure (e.g., at 20 reps, do 10-10; at 25, do 13-12). For burpees, steady and consistent beats fast and gassed. Transitions between movements should be immediate — no standing around. Track your rounds so you know where you are in the rep ladder.
Benchmark Notes
Wall balls and burpees both accumulate fatigue quickly; the escalating rep scheme means later rounds take exponentially longer. L5 (~3.5 rounds, completing through round 3 and partway into round 4) reflects a solid intermediate athlete managing breathing and pacing under the compounding volume. Primary limiters are burpee endurance and wall ball conditioning.
Modality Profile
Wall Ball is a weighted movement (external load with medicine ball), classified as Weightlifting. Burpee is a bodyweight gymnastics movement. With 2 movements split between these modalities, the breakdown is 50% Gymnastics and 50% Weightlifting.
