Working out hard or hardly working out?
Strap on a heart monitor ($50 and up) and you can see if you are exercising at the right intensity to achieve your exercise goals.
To maximize health benefits, the American Heart Association suggests a target heart rate for exercisers of 50 to 85 percent of their maximum heart rate, calculated by subtracting your age from 220.
When shopping for a heart rate monitor, you may want to choose a model that can calculate calories burned during your workout.
“A gadget that tracks the number of calories burned can be a great motivator for exercisers,” says Jessica Matthews, M.S., an exercise science expert with the American Council on Exercise.
