What step of the treadmill forecast is Coach Mimi performing when she announces, "our interval is a 2 minute push followed by a 1 minute base"?

The step of the treadmill forecast that Coach Mimi is performing by announcing "our interval is a 2 minute push followed by a 1 minute base" is pairing the efforts. This involves connecting two different types of intensity levels in a workout session, specifically pushing the heart rate into a higher effort zone followed by a return to a more moderate level of intensity. This pairing helps participants understand the rhythm of the workout and prepares them for what is to come, guiding them through the changes in pace and exertion that will be experienced during those intervals.

In this context, pairing the efforts assists in creating a structured approach to interval training, where participants can anticipate the changes and adjust their performance accordingly. It supports the overall goal of interval workouts in improving cardiovascular endurance and maximizing calorie burn, as participants switch between different effort levels.
