Which workout was described as generating a strong cardiorespiratory stimulus through simple calisthenics?

• A. Diane
• B. Fran
• C. Chelsea
• D. Elizabeth

Answer: (C)

Long-duration cardio delivered with simple bodyweight movements is being described. Chelsea does this by using a 30-minute AMRAP of five pull-ups, ten push-ups, and fifteen air squats. The focus is on sustaining effort over a long period, which drives aerobic capacity, with movements that are straightforward and scalable for many athletes. Because the stimulus comes from the length of the workout and the continuous repetition of basic calisthenics, the heart and lungs are challenged to keep pace rather than producing peak power or heavy lifting.

In contrast, the other workouts emphasize different aims in shorter time frames: one pairs heavy barbell work with challenging gymnastics movements, another is a very quick, high-intensity sprint of thrusters and pull-ups, and the last combines heavy cleans with ring dips. These require more strength, skill, or power and typically produce a different balance of intensity and workload. So the described option best aligns with a strong cardiorespiratory stimulus through simple calisthenics.
