What is the speed range for the walking warm-up in a 2G class?

The speed range for the walking warm-up in a 2G class is typically set between 3.5 to 4.5 mph. This range is deemed appropriate because it encourages participants to gradually elevate their heart rates while allowing them to remain comfortable. The walking warm-up is crucial for preparing the body for the more intense segments of the workout, focusing on mobility and increasing blood flow to the muscles. Maintaining a pace within this speed range helps ensure that all participants can engage effectively, regardless of their fitness levels, thereby promoting readiness for the upcoming exercises.

In contrast, the other ranges provided may either be too low, which could hinder the warm-up process, or too high, which could escalate heart rates too quickly and potentially lead to injury or discomfort. Hence, the 3.5 to 4.5 mph range strikes a balance between being challenging yet manageable, aligning with the goals of the warm-up phase in a 2G class setting.
