Workout Description

5 Rounds for Time 10 Hollow Rocks 10 V-Ups 10 Tuck Ups 10 second Hollow Hold 1 minute Rest

Why This Workout Is Easy

While core-intensive, this workout includes built-in rest periods (1 minute) between relatively short work periods (~30-40 seconds). The movements are basic gymnastics/core exercises with no load or complex skills. The 1:2 work-to-rest ratio prevents significant fatigue accumulation, and the movements don't compound each other's difficulty. Most CrossFitters can complete this as prescribed with good form.

Training Focus

This workout develops the following fitness attributes:

  • Stamina (7/10): High-volume core work with minimal rest tests local muscular endurance. Holding positions and repeating movements challenges midline stamina significantly.
  • Flexibility (4/10): Hollow positions and V-ups require decent hip flexor mobility and thoracic extension, but movements are achievable for most.
  • Endurance (3/10): The one-minute rest between rounds limits cardiovascular demand, though core fatigue builds over time. Five rounds creates moderate aerobic challenge.
  • Speed (3/10): While movements can be cycled quickly, the rest periods and emphasis on position control limit the speed component.
  • Strength (2/10): While core strength is required, movements are bodyweight-only and submaximal in nature. Focus is on control rather than max force.
  • Power (1/10): Movements are controlled and strict rather than explosive. Focus is on position maintenance and endurance rather than power output.

Movements

  • Hollow Rock
  • V-Up
  • Hollow Hold

Scaling Options

Reduce hollow rocks to 5 reps or substitute with dead bugs. Modify V-ups to knee tucks or partial V-ups with bent knees. Scale tuck-ups to supported tuck-ups with hands under hips. Reduce hollow hold to 5 seconds if form breaks. Can extend rest period to 90 seconds if needed. For advanced athletes, extend hollow hold to 20-30 seconds.

Scaling Explanation

Scale if unable to maintain proper hollow body position for 10 seconds, or if hip flexors fatigue prevents leg lift in V-ups. Priority is maintaining proper core engagement and spinal position throughout all movements. Target completion time is 12-15 minutes with consistent form across all rounds. Scale to preserve intended stimulus of core endurance rather than just getting through reps.

Intended Stimulus

Moderate-intensity core endurance workout targeting the anterior chain, lasting 12-15 minutes. Primary focus is on midline stabilization and core control under fatigue. Energy system is primarily oxidative with brief glycolytic demands during work intervals. Challenges both strength-endurance and movement quality maintenance.

Coach Insight

Maintain strict form throughout - quality over speed. Break up hollow rocks into sets of 5 if needed to maintain position. For V-ups and tuck-ups, focus on controlled eccentric movement. During hollow holds, ensure lower back remains pressed to ground. Use the rest periods fully - don't cut them short. Watch for form deterioration in later rounds, especially losing hollow body position or rushing transitions.

Benchmark Notes

This core-focused workout has similarities to Annie (50-40-30-20-10 double-unders + sit-ups) in terms of movement patterns and volume. Key differences: 1. Movement breakdown per round: - 10 Hollow Rocks: 1.5s each = 15s - 10 V-Ups: 2s each = 20s - 10 Tuck Ups: 1.5s each = 15s - 10s Hollow Hold = 10s - 1 min rest = 60s Base round time: 120s 2. Fatigue factors: - Rounds 1-2: 120s (fresh) - Round 3: 126s (1.05x fatigue) - Round 4: 132s (1.1x fatigue) - Round 5: 138s (1.15x fatigue) 3. Total time calculation: Elite (L10): ~300s (5:00) - Much faster than Annie benchmark due to forced rest periods - Core movements are less taxing than double-unders + sit-ups Intermediate (L5): ~540s (9:00) - Slower movement execution - More fatigue between rounds Beginner (L1): ~900s (15:00) - Significant rest needed between movements - Form breakdown on hollow positions Recap: Male/Female (unisex workout) L10: 5:00 (300s) L5: 9:00 (540s) L1: 15:00 (900s)

Modality Profile

All three movements (Hollow Rock, V-Up, Hollow Hold) are bodyweight/gymnastics movements requiring no external load or cyclical cardio. Therefore, this workout is 100% gymnastics modality.
