Workout Description

Why This Workout Is Medium

Total reps = 300; bodyweight load factor = 0.5; expected finish ~8:00. Density = (300 × 0.5) / 8 = 18.75 units/min → 20 pts. Movement complexity: average of Sit-Up (20) and Double-Under (60) = 40 pts. Time domain 5–12 min → 80 pts. Base score = 20×0.4 + 40×0.3 + 80×0.3 = 44. Descending scheme modifier ×0.95 → 41.8 (~42), mapping to Medium.

Training Focus

This workout develops the following fitness attributes:

• Speed (8/10): Fast rope turnover and quick sit-up cycling reward sharp transitions and high cadence.
• Stamina (7/10): High total reps (300) require continuous core and calf endurance without extended breaks.
• Endurance (6/10): Sustained, steady breathing for 5–10 minutes with heart rate elevated, especially during longer double-under sets.
• Power (4/10): Elastic rebound and timing on double-unders involve some spring, but not maximal explosiveness.
• Flexibility (2/10): Basic range of motion for sit-ups and light ankle/knee movement for jumping; no extreme mobility.
• Strength (1/10): No external loading; minimal absolute strength demand compared to barbell benchmarks.

Movements

• Double-Under
• Sit-Up

Scaling Options

Scale to: 100-80-60-40-20 Single-Under + Sit-Up • 50-40-30-20-10 Double-Under with anchored Sit-Up • 30-25-20-15-10 Double-Under + 40-30-20-10-10 Sit-Up

Scaling Explanation

These options preserve the fast, cyclical stimulus by adjusting rope complexity and core volume so you keep moving and finish near the intended time domain.

Intended Stimulus

A fast, punchy sprint that taxes coordination and cadence while keeping your core firing. You should move almost nonstop, with brief, controlled breaks only if double-unders unravel. The best efforts feel smooth and rhythmic, breathing steady, with the final 20–10 sets accelerating to an all-out finish.

Coach Insight

Open with composure on the 50s; settle into a rhythm and avoid redlining early. As the reps descend, increase pace and finish hard. Main tip: Keep the rope mechanics relaxed—elbows in, wrists turning, small jumps. Common pitfalls: Going unbroken too soon, yanking the rope from the shoulders, sloppy sit-up standards, and wasting time with rope tangles.

Benchmark Notes

This workout is identical to the iconic benchmark 'Annie' (50-40-30-20-10 double-unders + sit-ups for time). Using the Annie anchor as the foundation: L10: 300-360 sec, L5: 480-600 sec, L1: 780-960 sec. Movement breakdown: Double-unders in rhythm average 0.5 sec/rep when flowing, but expect breaks between sets. Sit-ups are approximately 1 sec/rep when fresh. Round-by-round analysis: Round 1 (50 reps each): DUs ~30-35 sec + transition ~3 sec + sit-ups ~55-60 sec = ~90 sec for elite. Round 2 (40 reps): DUs ~25-28 sec + transition + sit-ups ~45-48 sec = ~75 sec. Round 3 (30 reps): ~22-25 sec DUs + ~35-38 sec sit-ups = ~60 sec. Round 4 (20 reps): ~15-18 sec DUs + ~23-25 sec sit-ups = ~40 sec. Round 5 (10 reps): ~8-10 sec DUs + ~12-15 sec sit-ups = ~25 sec. Total for elite: ~290-315 sec, which aligns perfectly with the Annie L10 anchor of 300-360 sec. Applied progressive fatigue multipliers and set-breaking patterns for higher levels. L5 represents the median CrossFitter taking 480-600 sec, and L1 represents scaled athletes or beginners taking 780-960 sec. Final targets: L10: 360 sec, L5: 600 sec, L1: 960 sec.

Modality Profile

Half the work is monostructural jumping with the rope, and half is gymnastics via sit-ups. There is no external loading or weightlifting element. Time is split fairly evenly between quick double-under sets and fast-cycled sit-ups for most athletes.
