Step 1
Determine your maximum heart rate (MHR). This can be done by using formulas listed in books and training manuals, or by taking a stress test on a treadmill. A basic formula is 220 minus your age.
-
Step 2
Keep your running below 70 percent of your MHR if you're just getting into the sport. Sixty to 70 percent is recommended for aerobic conditioning.
-
Step 3
Use the heart-rate monitor for speed work if you are an intermediate or advanced runner.
-
Step 4
Run at 90 to 100 percent of MHR if you are preparing with speed work for a 5K or shorter race.
-
Step 5
Recognize when you have recovered from a hard interval or effort. This happens (typically) as soon as you drop to or below 120 beats per minute. Then you can begin your next interval, or repetition.
