In a cycle class, which factor is crucial for adjusting intensity?

Cadence
Body position
Resistance level
Workout duration

The correct answer is: Body position

In a cycle class, adjusting intensity is primarily related to the resistance level applied during the workout. The resistance level refers to the amount of force needed to pedal against the bike's resistance, which can be adjusted to make the exercise more challenging or manageable for participants. By increasing the resistance, individuals engage in more strenuous efforts that elevate their heart rates and enhance muscular strength. Conversely, lowering the resistance allows for a less intense workout, which can be beneficial for recovery or for beginners. While cadence, body position, and workout duration can also influence the overall cycling experience and effectiveness, they do not directly alter the intensity in the same way resistance does. Cadence refers to the speed of pedaling, and while a higher cadence can elevate heart rate, it is the combination with resistance that truly defines intensity. Body position affects comfort and performance but is less about intensity adjustment. Workout duration relates to how long participants are exercising but does not change the effort required at any given moment during the class.
