Workout Description

For Time (50 Reps of each): Box Jumps (24/20 in) Jumping Pull-Ups Kettlebell Swings (1/.75 pood) Walking Lunges Knees-to-Elbows Push Press (45/35 lb) Back Extensions Wall Ball Shots (20/14 lb) Burpees Double-Unders

Why This Workout Is Hard

High-volume chipper with 500 total reps across mixed modalities. Most athletes finish in 20–35 minutes if appropriately scaled, but cumulative fatigue, grip demands, midline fatigue, and breathing work make it challenging. Loads are light, yet cycle speed, transitions, and skill elements (double-unders, knees-to-elbows) raise the difficulty. Proper pacing and smart partitioning of big sets are crucial.

  • Advanced: 21:00-23:00
  • Intermediate: 25:00-27:30
  • Beginner: >38:20

Training Focus

This workout develops the following fitness attributes:

  • Stamina (9/10): Five hundred total reps taxes local muscular endurance in legs, shoulders, and grip. Success hinges on holding sustainable sets and minimizing drop-off across multiple similar movement patterns.
  • Endurance (7/10): Sustained breathing and heart rate with very limited rest across 20–35 minutes. Expect a steady aerobic demand while moving through long sets and managing transitions between stations.
  • Power (5/10): Explosiveness helps on box jumps, wall balls, and push press, but sustained output matters more than peak power. Efficient hip drive reduces fatigue and keeps cycle rates up.
  • Flexibility (4/10): Requires decent shoulder and thoracic mobility for overhead positions, plus hip flexion for knees-to-elbows and stable lumbar positioning on back extensions and wall balls.
  • Speed (4/10): Not a pure sprint; athletes must manage cadence. Quick but controlled cycling and crisp transitions pay off, especially on wall balls, push press, and burpees.
  • Strength (2/10): External loads are light and not limited by maximal strength. Most athletes are constrained by breathing, grip, and local fatigue rather than absolute force production.

Scaling Options

Scale to: Dirty Thirty (30 reps each) • Reduce loads/heights: 20/16 in box, KB 26/18 lb, bar 35/15 lb, ball 14/10 lb • Movement subs: ring rows, knee raises, 150 single-unders

Scaling Explanation

These adjustments preserve the chipper feel and movement patterns while matching intended intensity and time domain for your current capacity.

Intended Stimulus

A steady, grinding chipper. Move smoothly with minimal rest, keeping heart rate manageable while chipping away at big sets. Short, consistent breaks beat long pauses. The stimulus is aerobic with muscular endurance and grip fatigue, not maximal strength. Aim for continuous progress, tidy transitions, and consistent breathing to avoid redlining early.

Coach Insight

Pace the first half like you’ll need your lungs and grip later—because you will. Break sets early and consistently (e.g., 15-10-10-8-7) to avoid blow-ups. Keep transitions tight. The one tip: keep moving—5-10 seconds between mini-sets beats one long rest. Common mistakes: opening too hot, sloppy wall-ball standards, and ignoring grip fatigue before double-unders.

Benchmark Notes

These time targets set expectations from beginner to elite. If you routinely exceed the cap, scale reps or loads to land in the 20–30 minute range. Advanced athletes should aim to keep moving with short, planned breaks and efficient transitions to stay under 25 minutes.

Modality Profile

Six movements are gymnastics/bodyweight (box jumps, jumping pull-ups, walking lunges, knees-to-elbows, back extensions, burpees), one is monostructural (double-unders), and three use external loading (kettlebell swings, push press, wall balls). Expect dominant bodyweight fatigue with notable interference from light loading and jump rope skill.
