Workout Description

Why This Workout Is Hard

While 225/155 deadlifts and 400m runs are individually manageable, the 21-15-9 format with runs between sets creates significant leg fatigue and metabolic stress. The deadlifts become increasingly challenging as runs accumulate, and there's no built-in rest. The average CrossFitter will need to break up later deadlift sets and pace the runs. Most will finish in 12-15 minutes with considerable fatigue.

Training Focus

This workout develops the following fitness attributes:

• Strength (8/10): Heavy deadlifts at 225/155 represent a significant strength demand, requiring substantial force production even as fatigue accumulates.
• Endurance (7/10): The 400m runs between lifting sets create significant cardiovascular demand, especially when combined with heavy deadlifts. Recovery between efforts is minimal.
• Stamina (6/10): Moderate rep scheme tests muscular endurance, particularly in posterior chain. The combination with running creates cumulative fatigue.
• Speed (6/10): Quick transitions between lifts and runs are crucial. The descending rep scheme allows for faster cycling as sets get smaller.
• Flexibility (4/10): Standard hip and ankle mobility required for deadlifts and running. No extreme ranges of motion needed.
• Power (3/10): While deadlifts can be explosive, fatigue and running will likely slow the lifting tempo to a controlled pace.

Scaling Options

Scale deadlift weight to 65-75% of 1RM (185/135, 155/105, or 135/95). Sub 200m run or 250m row for those with running limitations. For significant strength limitations, reduce to 15-12-9 rep scheme and/or use Romanian deadlifts at lighter load. Advanced athletes can increase run to 600m or add weight to preserve intended stimulus.

Scaling Explanation

Scale if you cannot perform 15+ unbroken deadlifts at prescribed weight with perfect form, or if you cannot maintain sub-2:00 pace for 400m runs. Priority is maintaining safe deadlift technique throughout - reduce load if back rounds or hips rise early. Target time domain is 8-12 minutes at high but sustainable intensity. Scale to achieve 7/10 RPE while keeping deadlift form impeccable.

Intended Stimulus

Moderate-length glycolytic workout (8-12 minutes) combining heavy posterior chain loading with cardiovascular output. Tests ability to maintain deadlift technique under fatigue while managing heart rate spikes from running. Primary challenge is strength-endurance and lactate tolerance.

Coach Insight

Break deadlifts into 2-3 sets early (12-9, 8-7, 5-4) to preserve technique. Reset grip and brace between reps - don't touch-and-go when fatigued. Maintain steady run pace rather than sprinting. Use first 400m to assess sustainable pace. Most athletes break down technically in round of 15 - be especially mindful of lumbar position here. Rest 10-15 seconds before final set of 9 if needed.

Benchmark Notes

This workout is similar to DT in structure but with heavier deadlifts (225/155 vs 155/105) and running instead of cleans/jerks. Breaking it down: Round 1 (21 reps): - Deadlifts: 21 reps × 3 sec = 63 sec - 400m run: 90 sec - Transition: 10 sec Round 2 (15 reps): - Deadlifts: 15 reps × 3.5 sec (1.15x fatigue) = 53 sec - 400m run: 100 sec (1.1x fatigue) - Transition: 10 sec Round 3 (9 reps): - Deadlifts: 9 reps × 4 sec (1.3x fatigue) = 36 sec - 400m run: 110 sec (1.2x fatigue) Base time: 472 seconds Comparing to DT anchor (360-420s elite male), this should be ~25% slower due to: - Heavier deadlifts (225 vs 155) - Running vs barbell cycling - More transition time Final targets: Male L10: 360-390s (6:00-6:30) Male L5: 540s (9:00) Male L1: 900s (15:00) Female times adjusted +60s across all levels due to heavier relative loading: Female L10: 420-450s (7:00-7:30) Female L5: 600s (10:00) Female L1: 960s (16:00)

Modality Profile

Deadlift is a weightlifting (W) movement using external load. Run is a monostructural (M) cardio movement. With two movements from different modalities, the split is 50/50.
