For 20 or 30 minutes more, everyone dances and stretches to a vigorous beat. Students are taught to check their pulse rates at the beginning of the workout, in the middle, and during the cool-down period. That way, they can measure how well their hearts are handling the exercise. Over time, these kinds of workouts help heart muscles to get stronger and make lungs work more efficiently.
You can measure your resting heart rate by lying on the floor. With your first and second fingers, feel for your pulse on your neck under your ear. Count how many times it pulses in 10 seconds.
Multiply that number by six to figure out your pulse rate per minute. Most healthy adults have a resting heart rate of about 72 beats per minute. Yours may be lower than that because younger people usually have a lower rate than adults do. When you take part in active exercise, like dance, that rate will just about double. (more…)
