Stretches cant give you even .5 inch permanently, that is a measurement error, is not possible, even with a bad posture and a sedentary life. Check naturalheightgrowth.com, the guy there started a stretches program plus glucosamine, he gained at best 3 mm and only was in morning height. Although I dont understand why he says that everybody have hidden height, that is not true. The guys that claim have gained permanent height are measuring them wrong, only with a inversion table you will gain height but damage your spine, LL is the only way.
