Different exercises will affect your heart rate in different ways, and exercises that elevate your heart rate are a primary component of good cardiovascular health. The U.S. Department of Health & Human Services recommends 150 minutes of moderate aerobic activity or 75 minutes of intense aerobic activity a week.our target exercise heart rate for an effective cardio workout should be between 50 and 85 percent of your maximum. You can wear a heart monitor or check your rate manually at your wrist, neck, inside your elbow or at the top of your foot. Take your pulse for 10 seconds and multiply by six.
