The feeling of squatting on the low wall should have no positive effect if you can't say it clearly. But squatting on a higher wall should be able to exercise balance+attention+muscle strength. If you care about muscle strength ... you can squat on a higher wall, so that the nerves are tired first, followed by the muscles ... Nervous tension can be slimming in theory, but you should pay attention to safety. As for increasing ............., I'm not sure! I'm sure, I'm basically sure I'm blind.
