When exercising, especially long-term over a familiar course, you may notice your heart rate not going up as you'd expect. This is because your body has adapted to the workout that you're doing. Molly can increase her heart rate in a few ways: put the treadmill on an incline, run faster, or vary the speeds she is running, so they are always changing.
