It just seems like such a chore for a dumb reason. Bodybuilding has a bigger list of benefits then yoga's height addition; and yoga itself has bigger/better benefits then just height.
Trust me, most people here wouldn't care to do yoga because of how much work it is (it's repetitive, not hard). Think about it, people here would rather break a bone for height than work to improve on other qualities in their life and compensate for that; or even seek psychological help. If you think about it, if all you're doing yoga for is height then you're just feeding into your obsession instead of letting go.
One day you're not gonna be bothered enough to keep doing yoga and you will lose that added height. What then? Are you going to go back to the same psychologically broken man as before?
