Why This Workout Is Very Hard

Open WOD (Chipper). Ascending weight/skill: box jumps, C&J (up to 315lb), pistols. Extremely demanding strength/skill progression.

Training Focus

This workout develops the following fitness attributes:

  • Strength (9/10): The clean-and-jerk ladder progresses to extremely heavy weights (up to 315/205 lbs). Pistols require high unilateral leg strength. This WOD is a significant test of maximal C&J strength and strength endurance under fatigue.
  • Power (9/10): Clean-and-Jerks are a primary power movement. This WOD tests the ability to generate high power repeatedly with increasing loads while fatigued from other elements.
  • Endurance (8/10): A chipper for time (20-min cap) with box jumps, then clean-and-jerks with increasing weight (95lb up to 315lb) and decreasing reps, interspersed with single-leg squats (pistols). This is an extremely demanding test of strength, skill, and conditioning, with very heavy lifting at the end.
  • Stamina (8/10): Performing box jumps, then cycling C&J at progressively heavier weights, and performing high-volume pistols, requires significant leg explosive stamina, lifting stamina (full body for C&J), and unilateral leg/balance stamina (pistols).
  • Flexibility (7/10): Requires mobility for C&J (front rack, squat, overhead) at all loads. Excellent hip, knee, and ankle mobility for pistols. Hip flexion for box jumps.
  • Speed (4/10): Efficient cycling of box jumps and pistols is important. For C&Js, technique and power are more critical than raw cycling speed as weight increases. Pacing to reach and attempt heavy lifts is key.
