Some also award the AS-- Associate in Science degree.

Although it may seem difficult, lowering your breathing speed will help to lower your heart rate. Take a breath for 5-8 seconds, hold it for 3-5 seconds, and then exhale slowly for a count of 5-8 seconds.
Your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minuteâa drop of less than 12 beats a minute is considered abnormal. This ârecovery heart rateâ is measured as part of an exercise stress test. Does regular exercise lower resting heart rate? It may reduce it somewhat over time.
