Myth #1 – Weight training affects your height.
Many people claim and believe that weight lifting stunts growth if you start doing while you’re still growing. If you lift weights the proper way, it should not hinder growth and development. As long as the resistance is not so high that it would cause the bones to become more dense and thus close the epiphysis (the growth area of a long bone) then there should not be any detrimental effects.
According to the National Strength and Conditioning Association (which is one of the world’s premiere exercise authorities), weight training does not have any effect on growth and is generally safe for children and young teenagers.
Myth #2 – Weight training causes impotence/erectile dysfunction.
Research has shown that non-aerobic exercise (such as weight-lifting, sprint-training, and ball sports) could increase testosterone levels. And, if you don’t know it yet, having a low testosterone level is one of the main factors that contribute to impotence/erectile dysfunction. Additionally, regular exercise also improves blood circulation which is highly beneficial to sexual functions. So, from these alone, we can say that the myth is not true. Not entirely, at least.
What can really cause impotence/erectile dysfunction is the use of anabolic steroids. And if you are using steroids to help your muscles grow bigger, impotence is probably going to be one of the lesser problems you could encounter. If you are a teenager, steroid use can actually stop your bones from growing. Steroids can also damage your liver and increase your risk of having liver cancer, it can damage your kidneys, and it can also raise the cholesterol levels in your body thus increasing your chance of getting a heart attack or stroke. And that’s just naming a few of the side effects of steroids.
Myth #3 – Weight lifting causes high blood pressure.
Although weight lifting can cause a temporary increase in blood pressure (which is really part of the body’s natural reaction to strenuous activities), it actually offers some long-term benefits to blood pressure that outweigh the risk of a temporary spike for most people.
Regular exercise, including moderate weightlifting, provides many health benefits, among which is helping to lower blood pressure in the long term.
However, it is strongly advised that you go see a doctor and have a full body checkup before you take up weight training. This is to ensure that your body (especially your heart) will be able to handle the stress that you’re going to subject it to.
