This is a 28-minute continuous bike piece with progressive intensity—a structured, single-modality workout that avoids movement interference or skill demands. The RPM progression (70→100) creates manageable fatigue accumulation rather than a sudden spike. While the final minute at 100 RPM will be challenging, the extended warm-up and graduated increases allow most average CrossFitters to complete as prescribed. The limiting factor is aerobic capacity and leg endurance, not technique or extreme load.
This workout develops the following fitness attributes:
This workout consists entirely of a single monostructural movement: biking/riding on a stationary bike for 28 minutes with progressive intensity increases (70-100 rpm). There are no gymnastics (bodyweight) or weightlifting (external load) movements involved.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 8/10 | 28 minutes of continuous cycling maintains elevated heart rate throughout. Progressive intensity increases demand on aerobic system, testing cardiovascular capacity and sustained effort over extended duration. |
| Stamina | 7/10 | Sustained cycling output for 28 minutes with increasing cadence demands muscular endurance. Legs must maintain power output as fatigue accumulates and RPM increases progressively. |
| Strength | 1/10 | Cycling is primarily an endurance modality with minimal strength demands. No resistance or load component; focus is on aerobic capacity and muscular endurance rather than force production. |
| Flexibility | 2/10 | Basic hip and ankle mobility required for cycling position. Minimal range of motion demands; seated position limits flexibility requirements throughout the workout. |
| Power | 4/10 | Progressive cadence increases from 70 to 100 RPM require greater power output as intensity rises. Final minutes demand explosive leg turnover, though not pure power focus. |
| Speed | 6/10 | Cadence progression directly tests leg speed and cycling velocity. Final minute at 100 RPM demands quick leg turnover; pacing strategy critical for managing fatigue. |
