Why This Workout Is Very Hard
This workout stacks three barbell movements totaling 60 reps at 135/95 lb, bookended by 200 double-unders. The cleans pre-fatigue the pull and legs before shoulder-to-overheads tax the press, then clean-and-jerks demand both simultaneously under heavy fatigue. The barbell cycling volume rivals DT but with heavier combined loading and added skill demands. Most average athletes will struggle significantly to complete RX.

Training Focus
This workout develops the following fitness attributes:
- Stamina (8/10): High-rep barbell cycling across three related movements — cleans, S2OH, and clean-and-jerks — creates cumulative muscular fatigue in the posterior chain, shoulders, and grip, demanding significant muscular endurance throughout.
- Power (7/10): Cleans and jerks are inherently explosive movements. Maintaining bar speed and hip extension power across 60 reps — especially the clean-and-jerks — makes power output a primary and sustained demand throughout.
- Endurance (6/10): The combination of 200 double-unders and 60 barbell reps creates sustained cardiovascular demand. Athletes must manage heart rate across multiple high-skill movements, making aerobic capacity a significant limiting factor.
- Strength (6/10): 135/95 lb is a moderate-to-challenging load for high-rep cycling. Not maximal strength, but athletes must maintain positional integrity under fatigue across 60 total barbell reps, making strength a real factor.
- Speed (6/10): For-time format incentivizes fast barbell cycling and quick transitions between movements. Double-under efficiency and the ability to cycle the bar without excessive rest directly impact total time significantly.
- Flexibility (5/10): Cleans and jerks require adequate hip, ankle, and shoulder mobility. The overhead receiving position and front rack demand moderate flexibility, especially as fatigue accumulates across the high-rep sets.

Scaling Options
Weight: Scale to 95/65 lb for intermediate athletes or 75/55 lb for newer athletes — the goal is to move consistently, not grind. Movement substitutions: Replace double-unders with 200 single-unders or 50 penguin jumps per set for athletes still developing the skill. For the barbell movements, power cleans (no squat) are acceptable if squat clean mechanics are not yet solid. Push press can substitute for the jerk component in the S2OH and clean-and-jerk for athletes without a reliable jerk. Volume modifications: Reduce to 15 reps per barbell movement (15 cleans, 15 S2OH, 15 C&J) and 75 double-unders per set for athletes who would exceed 25 minutes at Rx.
Scaling Explanation
Scale the weight if you cannot perform at least 5 unbroken cleans at the prescribed load with solid mechanics — this workout requires cycling the barbell, not grinding singles from the start. Scale the double-unders if you cannot string together sets of 10+ consistently; tripping repeatedly will spike frustration and heart rate unnecessarily. Prioritize technique over load, especially on the clean-and-jerk, where a fatigued jerk can become a shoulder or wrist injury. The target time window is 12-20 minutes — if you're projected to go beyond 22-25 minutes, reduce reps or load to preserve the intended stimulus of sustained, hard effort rather than a survival grind.
Intended Stimulus
This is a moderate-to-long time domain workout targeting 12-20 minutes for most athletes. The structure progressively loads the barbell movements — cleans, then shoulder-to-overheads, then the combined clean-and-jerk — creating a cumulative fatigue challenge that tests both strength endurance and mental grit. The double-under buy-in and cash-out bookend the barbell work with a skill and conditioning tax, elevating heart rate before the bar and demanding focus when legs and lungs are already spent. The primary challenge is managing grip, shoulder fatigue, and breathing across 60 total barbell reps at a moderate-to-heavy load.
Coach Insight
Start the double-unders at a controlled, rhythmic pace — don't sprint them. You want your heart rate manageable before you touch the bar. For the cleans, consider sets of 5 with short rests (10-15 seconds) rather than grinding through big sets that destroy your grip early. The shoulder-to-overheads are where athletes often underestimate fatigue — your shoulders are already pre-fatigued from the cleans, so break these early and often: sets of 4-5 work well. The clean-and-jerks are the gut check. By rep 10, your grip and overhead stability will be tested — stay patient, breathe at the top of each rep, and avoid the temptation to rush. Common mistakes: going unbroken on cleans and paying for it on S2OH, letting the bar crash on the clean rather than riding it down, and burning out on the first 100 double-unders. The cash-out double-unders will feel brutal — break them into sets of 25-30 if needed and stay calm with your breathing.
Benchmark Notes
The primary limiters are barbell cycling under fatigue (especially the clean-and-jerks after 40 prior reps) and double-under skill/consistency. L5 (~12 min) assumes moderate double-under efficiency (~90s per set), cleans in sets of 5-10, S2OH unbroken or in 2 sets, and C&Js in singles/doubles late in the workout with significant rest.
Modality Profile
4 movements total: Double-Under (G), Clean (W), Shoulder-to-Overhead (W), Clean and Jerk (W). That's 1 Gymnastics and 3 Weightlifting movements. 1/4 = 25% G, 3/4 = 75% W, 0% M.
