Which method is suggested for adding variation to a movement pattern?

Altering the range of motion is an effective method for adding variation to a movement pattern. This approach involves modifying how far or to what extent a participant moves a joint or limb during an exercise. By changing the range of motion, instructors can create new challenges and engage different muscle fibers, enhancing the effectiveness of the workout and keeping participants motivated. This strategy allows for progression or regression based on the participants' fitness levels, encouraging improvement while also preventing boredom by introducing new sensations and challenges in the activity.

In contrast, changing the music tempo may enhance the experience but doesn’t manipulate the movement itself. Adjusting the number of participants does not fundamentally change the movement pattern and could lead to logistical issues rather than variations in exercise execution. Using the same exercise throughout could lead to monotony and a lack of full muscular engagement, which is the opposite of adding variation. Therefore, altering the range of motion is a strategic choice for introducing variety and adapting workouts to meet the dynamic needs of participants.
