Red Ribbon Week Awareness Wear Red Peace Love Cure Costume T Shirt tee
A general rule ofRed Ribbon Week Awareness Wear Red Peace Love Cure Costume T Shirt tee is that your maximum heart rate should be 220-age, in years. If you are 20 years old, 200 would be normal (assuming that you otherwise healthy). There are other formulas that give somewhat different maxima. This formula is merely a guideline. Some people have higher heart rates than the formula suggests. Your heart rate should not reach its maximum until you have been exerting yourself for a while. A few years ago, I had a treadmill routine in which I would run a half mile in 4.6 minutes followed by a 5.4 minute walk, repeated six times. After the first run, my heart rate would be 135. Each additional half mile would raise my heart rate by 5 bpm. After the sixth iteration, I would reach my maximum of 160. These guidelines are not a substitute for a proper EKG conducted and analyzed by a physician. About age 40, many doctors will recommend a stress test. A stress test will not reach your nominal maximum but it will normally reveal heart issues that would affect your workouts.
