This morning my resting heart (RHR) rate was 62. This is the first time since I started keeping track that it has been this low. The good news it that it puts me in the EXCELLENT category just below ATHLETIC (the highest group possible). Its a personal objective to make it to the ATHLETiC category (50-57 beats per minute) for my age range.

So why is it a good idea to track your resting heart rate? First it is a great indicator of heart fitness and health. A "normal" RHR is said to be between 60-100. In addition, you can use the results to manage your fitness routine. For example, if your RHR is 7 beats over you typical some time after exercise, its a sure sign you have been overtraining. An RHR higher than 100 puts you at risk of cardiac arrest.

To measure your heart rate place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 60 seconds. This will give you your beats to minutes.

Alternatively, you can get a heart rate monitor watch for use when you exercise. Certain gym equipment (e.g. Life Fitness) automatically synchronizes with your watch to display your heart rate on their screens.The following URL lists a few examples.

Although Dr. Mercola ((mercola.com) for his PEAK 8 high intensity interval training, advises training to hit 5 beats above your maximum heart rate, this is NOT recommended. The Canadian Medical Association and livestrong.com state that this is very dangerous. Instead, try not to exceed the 50%-90% of your maximum heart rate. You can calculate your maximum heart rate using the following formula: HRmax = 208 − (0.7 × age).
