How should the seat of a stationary bike be adjusted for optimal setup?

For optimal setup on a stationary bike, the seat should be adjusted so that it allows the rider's leg to be slightly flexed at full extension. This position ensures that when the pedal is at its lowest point, the leg is not fully locked out but has a slight bend at the knee. This slight flexion helps to maintain joint health and prevent strain or injury during exercise, as a fully extended leg can place excess pressure on the knee joint.

Additionally, a seat positioned to achieve this angle allows for effective pedaling mechanics, promoting better power output and efficiency while riding. Proper seat height also ensures comfort and prevents any undue stress on the hips or lower back, enhancing the overall workout experience. This setup is essential for both performance and safety when using a stationary bike.

The other options either recommend positions that could lead to discomfort or inefficient pedaling mechanics. For instance, positioning the seat at hip height may not provide the necessary knee flexion at the bottom of the pedal stroke, while setting it at the maximum height could result in overreaching and increased risk of injury. Adjusting to knee height fails to account for the natural range of motion during cycling, which is why the slight flex at full extension is optimal.
