Human height growth tends to saturate at age of 15 in females and 18-20 in males. But, many claim (i.e. "How to increase your height with easy exercises") that it is possible to increase your height even after the those ages, and even beyond 25.
The claims are made on the basis of stretching and their straightening the spine, for a modest (less than 2 inch) difference. Many studies refer to the "cobra stretch", "cat stretch", one leg straight up and other straightening exercises.
Is this true? Does a 25-year-old doing such exercises on regular basis have any chance of increasing their height?
