You can also try to slow your heart rate via breathing and relaxation techniques, by practicing other mind/body therapies such as biofeedback, or by taking supplemental calcium and magnesium. For women, start with 100 mg of magnesium (citrate, glycinate, or chelate) and increase the dose up to 350 mg daily.
Low resting heart rates, in the 60 to 70s bpm range, are considered generally healthy. High resting heart rates, especially when close to 100 bpm or higher, can be a sign of high stress levels or other medical conditions, how quickly the heart rate goes back to normal after exercise also holds a lot of information. Quicker indicates better cardiopulmonary fitness level.
