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.
The easiest way to compute this is to subtract your age from 220 â thatâs your maximum heart rate â then take 60 percent and 80 percent of that number. The results are the upper and lower end of your target heart rate zone: while you exercise, your heart rate per minute should fall somewhere between these two numbers.our heart will also acquire the ability to recover from the stress of exercise more quickly. In order to achieve a training effect, the American College of Sports Medicine suggests performing aerobic exercise sessions of 15 to 60 minutes a day, three to five days a week.
