Explain a benefit of using a heart rate monitor to measure bpm versus manually counting your pulse .

Using a heart rate monitor is often much more accurate than counting your pulse. When you count your pulse, you might undercount or overcount. Additionally, using a heart rate monitor is more efficient. You can get your pulse within seconds, and that's not the case with manually counting.
