Correction of hunchback and enlarged bust

The loss of back muscle strength will lead to the malalignment of the back bone, which is the central axis of the body.

The back bones are connected by 24 small bones and have many joints. The weakening of the back muscles and the effect of the earth's gravity can easily cause some people to develop a hunchback.

The balance of these people's body muscles is destroyed, their chests and buttocks sag, and their body shape deteriorates. Weaker muscle strength will also cause lower calories burned and slower metabolism.
