Video of the Week - The Science of Balance

You can shift your center of gravity by moving your arms and legs, or by bending and twisting your body. That is the reason that you flail your arms to keep your balance. Your body is trying to reposition its center of gravity over its base.

When you do things that you normally do, such as standing or walking, your body knows how to keep your center of gravity over your base. You learned that as an infant when you learned to walk. When you try something new, like Tree Pose, it takes practice for your body to learn how to keep your shifted center of gravity over a smaller base. The more you practice, the easier it gets to balance. Also remember that adding or removing weight will also shift your center of gravity. Holding the book in your hand will shift it a bit. The closer the added weight is to your center of gravity, the easier it will be to balance. With that in mind, adding a bowl of ice cream to my middle should make Tree Pose a bit easier. That is something that will require repeated experiments to test. Sounds fun to me. Click below to see "The Science of Balance" video.
