There are many sites out there that try to scam people out of their time and money by selling DVDs and instruction manuals about exercises to get taller. These stretches and exercises are not only a waste of time, but they can also be very harmful, resulting in slipped discs and torn tendons. Similarly, those that claim their special vitamin pills and supplements will make you taller are most likely selling you lies. These are to be avoided.
However, this doesn't mean that you exercises to get taller don't work. It's just better to do so when you're young and your body is still growing.
When we are babies, some of our bones are composed of cartilage. This cartilage shifts and melds and ossifies over time, forming the bones we have in adulthood. During this long process, we go from having 300 bones to only 206! In the middle of this, when we reach puberty, cartilage growth plates on our bones start to lengthen gradually. However, once these growth plates are done growing, no amount of stretching or exercise will make them lengthen by even a centimeter.
However, performing exercises to get taller while you're young can help make your bones strong. It also releases height growth hormones that help you grow taller faster. Keeping good exercise habits, as well as good posture, will keep your bones strong and healthy even into your older years, preventing bone weakening diseases and shrinking.
A good diet is also important. Depriving yourself of vital nutrients such as protein, amino acids, calories, and especially calcium can weaken your body and your bones, resulting in stunted growth and other complications. As you age, your body will take calcium from your bones, which is what often causes shrinking in elderly people.
This is why it's important to diet and exercise to increase height while you're young. Doing so will ensure that your body flourishes and grows as much as it can during this vital period.
If you're past adulthood and wish to grow taller, don't lose hope. There are several height enhancing alterations you can make to your wardrobe, shoes, hair, and more to make yourself look taller and slimmer.
