Workout Description
For Time
150 Sit-Ups
1000 meter Row
150 Sit-Ups
Why This Workout Is Medium
Estimated density uses 300 sit-ups plus ~200 rowing strokes over 18–20 minutes at a 0.5 bodyweight load factor, yielding ~12–14 units/min (20 pts). Movement complexity averages Basic (20). Time domain sits in the 12–20 minute window (70). Base score ≈ 0.4×20 + 0.3×20 + 0.3×70 = 35. No modifiers apply. Overall difficulty: Medium.

Training Focus
This workout develops the following fitness attributes:
- Stamina (8/10): High abdominal and hip flexor endurance required for 300 total sit-ups. Success hinges on repeating large sets with short, controlled breaks without significant drop-off.
- Endurance (7/10): Sustained aerobic demand from a 1,000 m row and long duration sit-up volume. Heart rate should sit in a manageable zone while breathing stays rhythmic throughout the middle portion of the workout.
- Speed (5/10): Faster cycling helps, but pacing is key. Efficient transitions and consistent sit-up cadence matter more than sprinting any single segment.
- Flexibility (3/10): Basic range of motion: full trunk flexion/extension on sit-ups and safe hip position on the rower. Mobility demands are modest and mostly positional.
- Power (2/10): There is little need for explosive output. The row can use powerful drives, but the overall session rewards steady work more than peak power.
- Strength (1/10): No external load is used. The challenge is not maximal force but sustaining submaximal contractions across many repetitions.
Scaling Options
Scale to: 100 Sit-Up • 800 m Row • 100 Sit-Up • 120 Sit-Up • 750 m Row • 120 Sit-Up • 200 total Sit-Up (100-Row-100) with anchored feet or tuck crunches
Scaling Explanation
These options reduce total midline volume and rowing demand while preserving the chipper structure and intended steady, sustainable stimulus.
Intended Stimulus
A steady, breathing-focused grinder with a pronounced midline burn. Move the first 150 sit-ups in manageable sets, row at a controlled pace you could hold for a 2K, then fight to maintain cadence on the final 150. Minimal downtime, short breaks, and consistent mechanics deliver the best times.
Coach Insight
Open with repeatable sit-up sets (15–30 reps) and 3–5 seconds of rest. Row at a pace you’d hold for a strong but sustainable 2K, not a sprint.
The one thing: Save your hip flexors—don’t race the first 150. Smooth to fast beats fast to slow.
Common mistakes: blowing up early, sloppy sit-up standards (shoulders past hips, hands to floor), and rowing spikes that ruin the final sit-up set.
Benchmark Notes
Times range from beginner finishing around 35 minutes to elite near 13–14 minutes. Hitting L5 (~20 minutes) means steady sets of sit-ups with minimal rest and a controlled 1K row. Faster levels require tighter sit-up pacing and a stronger 1K row without redlining.
Modality Profile
Most time is spent on sit-ups (gymnastics), split into two large sets that dominate the workout. The 1,000 m row contributes a quarter of total time as a steady monostructural effort. There is no external loading or weightlifting component.
