Workout Description

Why This Workout Is Hard

This workout demands sustained output across 225 double unders, 135 deadlifts at moderate load, and 90 toes-to-bar. The back-loaded structure compounds fatigue significantly in later rounds, requiring substantial grip endurance, core stamina, and posterior chain resilience. The 21-28 minute time domain with heavy barbell cycling places this firmly in the hard category.

Training Focus

This workout develops the following fitness attributes:

• Stamina (9/10): High-volume deadlifts and toes-to-bar create significant local muscular fatigue, demanding the ability to sustain muscular contractions under acidosis and peripheral fatigue.
• Endurance (8/10): The 21-28 minute time domain with continuous work demands sustained aerobic output and oxidative system development throughout the ascending rep scheme.
• Strength (8/10): 135 deadlifts at 185/125 lb require substantial posterior chain strength, particularly as fatigue accumulates through the back-loaded structure.
• Power (7/10): Double unders require explosive wrist action and calf power, while deadlifts at moderate load with cycling demand repeated hip extension power output.
• Speed (5/10): Speed is secondary to sustainability in this workout; the focus is on maintaining consistent movement velocity rather than maximal speed output.
• Flexibility (4/10): Toes-to-bar require adequate hip flexor and hamstring flexibility, while deadlifts demand basic hip hinge mobility. Not a primary limiter for most athletes.

Movements

• Toes-to-Bar
• Deadlift

Scaling Options

Reduce deadlift load to 135/95 lb, substitute single unders (2:1 ratio), and scale toes-to-bar to hanging knee raises or V-ups. Maintain the ascending rep scheme structure.

Scaling Explanation

These modifications preserve the back-loaded challenge while reducing absolute load and skill demand. The 2:1 single under ratio maintains time under tension for the shoulders and core, while lighter deadlifts allow athletes to sustain quality hip hinge patterns through the increasing volume.

Intended Stimulus

A grueling test of local muscular stamina with an ascending challenge that forces athletes to manage fatigue strategically. The workout targets posterior chain endurance through sustained deadlift cycling, core capacity through high-volume toes-to-bar, and shoulder stamina through accumulating double unders. Athletes should experience progressive muscle fatigue, particularly in the grip and midline, with the final three rounds demanding mental fortitude to maintain movement quality.

Coach Insight

Approach each phase as its own mini-workout with brief mental resets between. In rounds 1-3, establish your rhythm and stay conservative—these are your 'banking' rounds. Rounds 4-6 are where pacing matters most; break the deadlifts early (sets of 5-7) before your grip fails. In the final three rounds, your grip will be the primary limiter—expect to break the deadlifts into sets of 4-5 and the toes-to-bar into sets of 3-5. Keep double unders smooth; if you trip, take 3 breaths before restarting. The athletes who win this workout are those who negative split their round times by staying disciplined early.

Benchmark Notes

Level 10 (sub-11:00) represents elite athletes with unbroken double unders, fast deadlift cycling (touch-and-go sets), and large toes-to-bar sets throughout. Level 5 (17:00-19:00) reflects intermediate athletes who may need to break movements in later rounds and take longer transitions. Level 1 (28:00+) accounts for athletes who struggle with double unders and require significant breaks on all movements. The ascending structure means times accelerate significantly based on how well athletes manage the back-loaded volume.

Modality Profile

Weightlifting dominates at 45% due to 135 moderate-load deadlifts requiring sustained barbell cycling. Gymnastics comprises 35% with 90 toes-to-bar demanding significant core and grip work. The metabolic component at 20% comes from 225 double unders providing cardiovascular demand and shoulder fatigue accumulation.
