What will improve kyphosis of the spine?

Kyphosis: Most often, kyphosis only worsens as time goes on... due to gravity and the aging process of 'drying-up' of the discs. The anterior part of the spine gets shorter and the body leans more forward. Good posture and active strengthening of the posterior (back) muslces can keep you more upright... Really changing the kyphosis angle is almost impossible without surgery though...
