Knowing your target heart rate as you work out can help you gauge how hard you are pushing yourself.
Exercising at the right intensity helps you get the most out of your workout and strengthens the heart.
“The heart is like any other muscle in the body – you want to work on strengthening it, so by doing exercise you work on making the heart more efficient pumping blood to the muscles,” said Eric Simmons, personal trainer.
Monitoring your heart rate lets you know if you are working too hard or not hard enough. Measuring your progress starts by calculating your maximum heart rate which is about the highest number of beats the heart can sustain during one minute of exercise.
If you are 40-years-old, your maximum heart rate is about 180-beats-per-minute but you should not often push your heart to that extreme. Instead, experts say exercise within 60 to 80 percent of your maximum heart rate.
