Lifting weights at a gym can actually hamper the height of your child, so don't allow it. However, sports like basketball, tennis and badminton are all great ways to promote growth hormones in the body and help your child grow taller. Running, swimming and cycling are also great options.
Hereof, can you stretch yourself to get taller?
Hanging and stretching can reverse the compression, making you slightly taller until your spine compresses again. Spinal compression can reduce your height temporarily by 1%. In tall people this can be as much as a half inch. Stretching and hanging and lying down can restore this 1%, but won't make you taller [5].
