Workout Description

FOR TIME 21-15-12-9-6-3 reps for time of: Medicine Ball Squats, 9/6 kg Knee Raises Jumping Pull-ups

Why This Workout Is Medium

This workout combines light loading (9/6kg medicine balls are minimal), moderate volume (66 total reps), and fundamental movements with no complex skills. The descending rep scheme (21-15-12-9-6-3) provides natural pacing and fatigue management. While continuous work creates some intensity, the light weight and bodyweight pull-up variation allow most average CrossFitters to complete unbroken or with minimal breaks. Expected completion time is 8-12 minutes, manageable for intermediate athletes.

Training Focus

This workout develops the following fitness attributes:

  • Stamina (8/10): High total volume of 66 reps across three movement patterns tests muscular endurance significantly. Accumulated fatigue from medicine ball squats and knee raises challenges sustained output capacity.
  • Endurance (7/10): The descending rep scheme with continuous movement demands sustained cardiovascular output. The for-time format creates consistent aerobic demand without full recovery between movements.
  • Speed (7/10): For-time format incentivizes rapid movement cycling and minimal transitions. Descending rep scheme allows accelerating pace as fatigue accumulates. Quick transitions between three distinct movements are critical.
  • Power (6/10): Jumping pull-ups are inherently explosive movements. Medicine ball squats with light load emphasize speed and power. Knee raises require dynamic hip flexor power throughout the workout.
  • Flexibility (5/10): Medicine ball squats require moderate hip and ankle mobility. Knee raises demand core and hip flexor flexibility. Jumping pull-ups need shoulder mobility but less than strict variations.
  • Strength (4/10): Light medicine ball load (9/6kg) emphasizes muscular endurance over maximal strength. Jumping pull-ups reduce strength demand compared to strict pull-ups, focusing on power-endurance.

Movements

  • Hanging Knee Raise
  • Jumping Pull-Up

Scaling Options

Weight reduction: scale med ball to 6/4 kg if the standard load causes breakdown in squat mechanics. Movement substitutions: replace knee raises with lying knee tucks or a reduced range hanging knee raise from a low bar if grip or shoulder fatigue is a limiter; replace jumping pull-ups with ring rows (body at 45 degrees) if shoulder mobility or jumping mechanics are an issue. Volume modification: reduce to a 15-12-9-6 rep scheme for newer athletes or those recovering from injury to keep the workout under 15 minutes. Alternatively, reduce the starting round to 15 reps (15-12-9-6-3) if the full 21-rep opening round causes excessive rest periods.

Scaling Explanation

Scale if you cannot perform at least 10 unbroken air squats with good form, cannot hang from a bar for 15 seconds, or if jumping pull-ups cause shoulder discomfort. Prioritize movement quality over Rx loads — a sloppy med ball squat under fatigue is a recipe for lower back strain. The target completion time is 10-18 minutes; if an athlete is projected beyond 20 minutes due to load or volume, scaling is the right call to preserve the intended moderate conditioning stimulus. Newer athletes should default to the reduced rep scheme to experience the full descending structure without burning out in the first two rounds.

Intended Stimulus

This is a moderate-duration chipper-style workout targeting 10-18 minutes of continuous effort. The descending rep scheme (21-15-12-9-6-3) creates a psychological and physical reward as rounds get shorter, making it feel like a sprint to the finish. Energy demand is a hard, sustained effort — expect burning legs from the med ball squats and core fatigue from knee raises accumulating alongside the cardiovascular push. The primary challenge is conditioning and pacing discipline; no single movement is technically demanding, making this a pure fitness test where smart effort management wins.

Coach Insight

The opening round of 21 reps is the trap — resist the urge to go unbroken on everything and pay for it in rounds 3 and 4. Break the med ball squats into manageable sets from the start: consider 12-9, then 8-7, then smaller sets as rounds shrink. Knee raises are your rest — keep a controlled kip and breathe at the top of each rep. Jumping pull-ups should feel almost effortless; use a full arm extension at the bottom and an explosive leg drive to avoid turning them into a grind. Transitions between movements should be under 5 seconds — no standing and staring. Key technique cue on med ball squats: keep the ball at chest height, elbows up, and drive knees out to protect the hips under fatigue. Common mistakes include letting the squat become a good-morning as the core tires, and losing range of motion on knee raises when the abs burn. The rounds of 9, 6, and 3 are your gas pedal — push hard here.

Benchmark Notes

Knee raises and med ball squat pacing are the primary limiters as core fatigue accumulates through the descending sets; jumping pull-ups are low skill but add systemic demand. L5 (~8 min) breaks into manageable sets of 10-11/5-6 on squats and knee raises, moving steadily through the back half.

Modality Profile

Medicine Ball Squat is Weightlifting (external load), Hanging Knee Raise is Gymnastics (bodyweight), Jumping Pull-Up is Gymnastics (bodyweight). 2 out of 3 movements are Gymnastics, 1 out of 3 is Weightlifting.
