Workout Description

Why This Workout Is Hard

The 21-minute AMRAP creates relentless cumulative fatigue. Squat cleans at 155/105 lb are technically demanding and heavy, and they follow push-ups that pre-fatigue the upper body and precede box jumps that tax the legs — creating full-body interference each round. The long time domain prevents pacing relief, and squat cleans under fatigue will force frequent breaks, making this Hard for the average athlete.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Push-ups and box jumps accumulate significant volume over 21 minutes, taxing upper body pushing muscles and legs repeatedly. Squat cleans add muscular fatigue that compounds across rounds.
• Power (7/10): Squat cleans are inherently explosive, requiring a powerful pull and hip extension. Box jumps also demand explosive leg drive. Two of three movements are power-dependent, making this a notably power-oriented workout.
• Endurance (7/10): A 21-minute AMRAP demands sustained cardiovascular output throughout. The combination of three varied movements keeps heart rate elevated, requiring solid aerobic capacity to maintain consistent round times.
• Strength (6/10): Squat cleans at 155/105 lb represent a moderate-to-heavy load requiring real strength, especially as fatigue accumulates. Push-ups and box jumps add minimal absolute strength demand.
• Flexibility (6/10): Squat cleans demand thorough hip, ankle, and thoracic mobility to hit a proper receiving position. Box jumps and push-ups require basic range of motion, but the clean elevates overall flexibility needs.
• Speed (6/10): Efficient transitions and cycling speed matter in an AMRAP format. Squat cleans limit cycling speed due to load, but push-ups and box jumps can be moved through quickly to maximize round count.

Movements

• Squat Clean
• Push-Up
• Box Jump

Scaling Options

Weight: Reduce squat clean to 115/75 lb (roughly 75% of Rx) for athletes who can cycle the barbell with good mechanics, or 95/65 lb for developing athletes. If the squat clean is a limiting skill, substitute dumbbell squat cleans (50/35 lb each) or a barbell power clean to a front squat. Push-ups: Sub knee push-ups or elevate hands to a box/bench to maintain full range of motion — avoid half-rep push-ups at Rx. Box jumps: Reduce height to 20/16 in, substitute step-ups for athletes with knee or Achilles concerns, or use a lower box with a step-down. Volume: Reduce to 9 push-ups / 4 squat cleans / 8 box jumps if the full rep scheme causes excessive rest periods. Time: Keep the full 21 minutes — the time domain is part of the stimulus.

Scaling Explanation

Scale the squat clean weight if you cannot perform at least 3 technically sound reps unbroken when fresh — form breakdown under fatigue in a 21-minute AMRAP is a recipe for injury, not adaptation. Scale push-ups if you cannot complete 8+ in a row with a rigid plank position; a sagging lower back under fatigue is a red flag. The goal is to keep moving with minimal rest — if you're standing at the barbell for 30+ seconds between every single, the load is too heavy. Prioritize technique over load on the squat cleans every time; this is a conditioning workout, not a max-effort day. Athletes should be working at roughly an 8/10 effort throughout — uncomfortable and challenging, but never so gassed that mechanics collapse. The target is consistent, quality movement for the full 21 minutes.

Intended Stimulus

This is a moderate-to-long aerobic grind lasting the full 21 minutes, designed to test your ability to sustain output across a triplet that combines upper body pushing, a heavy barbell skill movement, and explosive lower body work. The squat clean at 155/105 lb is the anchor — it's heavy enough to demand respect but light enough to cycle if you're efficient. The intended stimulus is a hard, sustained effort where your engine and your technique are both tested. Expect your lungs and legs to be working constantly, with the squat cleans acting as a recurring checkpoint on your mechanics under fatigue.

Coach Insight

The squat cleans are the governor of this workout — let them dictate your pace from the start. Do NOT go out hot on push-ups and box jumps only to hit a wall on the barbell. Aim for a consistent, repeatable pace across all 21 minutes rather than a fast first few rounds. For push-ups, break early: sets of 6-5 or 4-4-3 will keep your shoulders fresher for the cleans. On the squat cleans, singles are completely acceptable and often smarter than touch-and-go — reset your hips, brace your core, and pull yourself under the bar rather than muscling it up. Avoid the common mistake of catching high and riding it down with a soft core; receive the bar in a strong front rack and hit depth confidently. For box jumps, use a step-down strategy to protect your Achilles and keep your heart rate from spiking unnecessarily — this is a 21-minute workout, not a sprint. Common mistakes: going unbroken on push-ups early and dying on round 3, power cleaning instead of squat cleaning (check the standard), and bounding box jumps that spike fatigue. Target 6-8+ rounds for competitive athletes; 4-6 rounds is solid for most.

Benchmark Notes

A 21-minute AMRAP of 11 push-ups, 5 squat cleans at 155/105 lb and 10 box jumps. 155 lb is about 70% of an average athlete's clean. L5 (9-10.5 rounds) takes about 2 minutes a round. Elite athletes hold under 50 seconds a round (23+).

Modality Profile

3 movements total: Push-Up (G), Box Jump (G), Squat Clean (W). 2 Gymnastics bodyweight movements and 1 Weightlifting barbell movement = 67% G, 0% M, 33% W.
