Workout Description

Why This Workout Is Extremely Hard

This workout combines heavy barbell loads (225/155 deadlifts, 185/125 cleans) with high-skill gymnastics (35 total muscle-ups) across two distinct phases. The structured 2-minute rest between rounds provides recovery, but the 21 deadlifts-to-7 muscle-ups sequence creates significant grip and shoulder fatigue. The final 3 rounds of squat cleans, toes-to-bar, and 400m runs with zero rest compounds fatigue across multiple energy systems. Total volume and skill demands exceed what most average CrossFitters can execute as prescribed within the time cap.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): High rep deadlifts, muscle-ups, squat cleans, and toes-to-bar across multiple rounds test muscular endurance. Cumulative fatigue from 105 deadlifts and 45 muscle-ups demands sustained output.
• Endurance (7/10): The 400m runs in final rounds and sustained 35-45 minute effort demand cardiovascular capacity. Moderate aerobic demand with structured rest periods in first phase.
• Strength (7/10): Heavy deadlifts at 225/155 lb and squat cleans at 185/125 lb require significant force production. Loads are substantial but not maximal; strength is secondary to volume.
• Flexibility (6/10): Bar muscle-ups demand shoulder mobility and thoracic extension. Squat cleans require ankle and hip mobility. Toes-to-bar needs hip flexor and hamstring flexibility. Moderate-to-high demands.
• Power (6/10): Deadlifts and squat cleans require explosive hip extension. Bar muscle-ups demand explosive pulling power. However, fatigue accumulation reduces explosive capacity as workout progresses.
• Speed (5/10): Minimal rest between final three rounds creates steady pacing demands. First phase has structured 2-minute rest. Transitions matter but not sprint-cycling focused overall.

Scaling Options

Deadlifts: Scale to 185/135 lb (intermediate) or 155/105 lb (beginner). Bar Muscle-Ups: Sub chest-to-bar pull-ups, then banded pull-ups or jumping chest-to-bar if needed. Reduce reps to 5 per round if skill is limiting. Squat Cleans: Scale to 155/105 lb (intermediate) or 135/85 lb (beginner); sub power cleans if squat mechanics break down under fatigue. Reduce reps to 10-12 if needed. Toes-to-Bar: Sub knees-to-chest, hanging knee raises, or V-ups; reduce to 20 reps per round. Volume: Consider 4 rounds in Part 1 or 2 rounds in Part 2 for athletes who are newer to high-volume barbell work. Time cap: Enforce a hard 40-minute cap and note where athletes finish.

Scaling Explanation

Scale this workout if you cannot perform at least 10 unbroken deadlifts at Rx weight with a neutral spine, if you have fewer than 3-5 bar muscle-ups strung together, or if your squat clean mechanics deteriorate significantly under load or fatigue. The priority here is keeping the stimulus intact — sustained, hard effort with quality movement — not hitting the Rx numbers. An athlete grinding through ugly, slow singles on squat cleans for 20 minutes is not getting the intended training effect and risks injury. Scale the load so you can move with purpose and confidence. The goal is to finish Part 2 feeling like you left everything on the floor, not like you survived a technique breakdown. Target completion time is 35-42 minutes for well-scaled athletes.

Intended Stimulus

This is a long-duration, high-output grind targeting the 35-45 minute time domain. The two-part structure is intentional — the first half (5 rounds with rest) builds fatigue in your posterior chain and upper body pulling capacity, while the second half (3 rounds, no rest) tests your ability to sustain output when you're already deep in the hole. Expect a hard, sustained effort that taxes your aerobic engine, grip, and mental toughness simultaneously. The primary challenges are strength-endurance on the deadlifts and squat cleans, skill under fatigue on bar muscle-ups and toes-to-bar, and raw mental fortitude when the rest periods disappear in the back half.

Coach Insight

Use the 2-minute rest periods in Part 1 strategically — they are a gift, not a suggestion. Treat each round of 21 deadlifts as touch-and-go sets broken into 3 sets of 7 or 7-7-7 with a breath reset at the top, keeping your hips loaded and back flat. Do NOT go unbroken and blow up your grip early. On bar muscle-ups, aim for 4-3 or 3-2-2 — smooth, controlled kips with a strong hip drive and early transition. Avoid muscling reps; fatigue will punish that fast. When you hit Part 2, the squat cleans at 185/125 are the biggest threat — treat these as singles or doubles from the start. Do NOT try to cycle them touch-and-go when your back is already taxed from 105 deadlifts. Toes-to-bar should be broken into sets of 10-10-10 or 10-8-7-5 to protect your grip and midline. Use the 400m run as active recovery — a controlled, honest pace that lets your hands and lungs reset before the next round. Common mistakes: going too fast in Round 1 of Part 1 and dying in Round 3-4, trying to cycle squat cleans when fatigued, and letting the toes-to-bar become a death march of singles.

Benchmark Notes

Bar muscle-ups and heavy squat cleans are the primary limiters — most athletes below L5 will cap out during the squat clean/TTB/run rounds. L5 (~43 min) finishes with broken sets on cleans, singles/small sets on TTB, and steady running, having ground through the deadlift/BMU rounds in 18-20 min total work time.
