In a cycle class, adjusting intensity is primarily influenced by the resistance level. This is because the resistance level directly impacts how hard the participant has to work against the pedals. When the resistance is increased, it requires more effort to maintain the same cadence, thus raising the overall intensity of the workout.

While cadence, body position, and workout duration also play roles in the cycling experience, they do not directly adjust the intensity in the same way that resistance does. Cadence refers to how fast participants are pedaling, which can vary but does not necessarily change the difficulty unless paired with resistance. Body position can affect comfort and efficiency, but it does not inherently alter the intensity of the pedaling effort. Conversely, workout duration denotes the length of the session rather than the difficulty of the individual segments within it. Therefore, resistance level is the crucial factor for directly modifying intensity during a cycle class.
