Workout Description

Why This Workout Is Very Hard

The sheer volume is the killer here: 3 rounds totals 3,000m running, 300 jumping jacks, 150 pull-ups, 300 sit-ups, and 300 air squats. The 150 pull-ups alone rival Murph's volume and will destroy grip and lats. Running between every movement prevents recovery. Estimated 45-70+ minutes for average athletes, creating brutal cumulative fatigue across all muscle groups.

Training Focus

This workout develops the following fitness attributes:

• Stamina (10/10): Massive volume of 300 jumping jacks, 150 pull-ups, 300 sit-ups, and 300 air squats across 3 rounds demands exceptional muscular endurance in virtually every major muscle group.
• Endurance (9/10): Five 200m runs per round across 3 rounds creates significant cardiovascular demand. Continuous movement between running and high-rep bodyweight exercises keeps heart rate elevated throughout the workout.
• Speed (5/10): For-time format incentivizes efficient pacing and quick transitions between movements. Managing run pace and breaking up high-rep sets strategically is critical to a competitive finish time.
• Flexibility (2/10): Basic range of motion required for sit-ups, air squats, and pull-ups. No extreme mobility demands, though hip flexor and shoulder flexibility will be tested under fatigue.
• Strength (2/10): Entirely bodyweight movements with no external loading. Pull-ups require relative strength, but the high rep counts shift the stimulus firmly toward endurance rather than maximal force production.
• Power (1/10): No explosive or ballistic movements are programmed. Jumping jacks have a minor plyometric component, but the overall stimulus is sustained aerobic and muscular endurance, not power output.

Scaling Options

Pull-Up Scaling: Substitute banded pull-ups, ring rows, or jumping pull-ups. Reduce reps to 25-35 per round if needed. For athletes with no pull-up capacity, use 50 ring rows or 50 TRX rows as a direct substitute. Volume Scaling: Reduce to 2 rounds for athletes newer to CrossFit or those with limited conditioning base. Reduce jumping jacks to 50, sit-ups to 50, and air squats to 50 per round for a lighter version. Run Scaling: Shorten to 100m runs per segment if a 200m track is unavailable or if the athlete has mobility/injury limitations. Substitute 250m row or 1 minute bike for each 200m run if needed. Movement Substitutions: Replace sit-ups with AbMat sit-ups or V-ups for variety; substitute box step-ups (10 reps) for air squats if knee issues are present.

Scaling Explanation

Scale this workout if you cannot complete at least 5 strict or kipping pull-ups unbroken, if your estimated finish time exceeds 55-60 minutes, or if you are newer than 6 months to CrossFit. The pull-ups are the primary limiter — if you cannot perform them with reasonable efficiency, substitute immediately to preserve the intended conditioning stimulus. Prioritize keeping moving over performing Rx movements. The goal is continuous effort with short, planned breaks — not long rest periods waiting to recover. Target finish time for Rx athletes is 30-45 minutes; scaled athletes should aim for 35-50 minutes. If you find yourself resting more than 2 minutes at any point, the volume or movement is too advanced for today. Intensity here means sustained effort, not speed — protect your technique on pull-ups and squats especially as fatigue accumulates in rounds two and three.

Intended Stimulus

This is a long, steady-engine conditioning workout targeting the 30-50 minute time domain. The repeated 200m runs act as active recovery and pacing checkpoints between high-rep bodyweight movements, creating a sustained aerobic demand throughout. The primary challenge is mental and muscular endurance — the sheer volume of reps (350+ movements plus 1800m of running) will test your ability to stay composed, keep moving, and manage fatigue across all three rounds. Think of this as a grind, not a sprint. The pull-ups are the wildcard that will separate athletes and dictate overall pacing.

Coach Insight

The runs are your reset button — use them to control your breathing and mentally prepare for the next movement, not to race. Start conservatively on round one; athletes who go out hot on jumping jacks and sit-ups will pay dearly by round three. For pull-ups, break them early and often — sets of 5-10 with short rest beats going to failure and hanging on the bar. Suggested pull-up breakdowns: Rx athletes try 10x5 or 5x10; intermediate athletes go 5x5 with 10-15 second rests. Jumping jacks should be unbroken or in two large sets — they're a recovery movement, not a challenge. Sit-ups: pace at a steady rhythm, avoid rushing and burning out your hip flexors early. Air squats: keep depth consistent, use a controlled tempo, and don't let form deteriorate in round three. Common mistakes include sprinting the runs, going unbroken on pull-ups in round one, and underestimating cumulative fatigue. Transitions between movements should be deliberate but not slow — keep rest periods intentional.

Benchmark Notes

Three rounds, each with 1,000 m of running in 200 m pieces, 100 jumping jacks, 50 pull-ups, 100 sit-ups and 100 air squats: 3 km of running and 1,050 bodyweight reps in all. Elite athletes need about 35 minutes. L5 (60-68 min) runs about 5:30 per 1,000 m and breaks the pull-ups into sets of 5-8.

Modality Profile

5 movements total: Pull-Up, Sit-Up, Air Squat, Jumping Jack = Gymnastics (4 movements, 80%); Run = Monostructural (1 movement, 20%). Rounded: G=60, M=20, W=0. Note: Jumping Jack is a bodyweight movement classified as Gymnastics.
