Callanetics for Your Upper Back

I think I've found a way to use the power of Callanetics to help the weakness in my upper back. I have been overweight and large breasted for over a decade now and it has really done a number on my spine and my muscle strength, especially above the bra line.

Although I'm no longer a 44G, even at a much-reduced 34DD, it's still a lot of weight to carry in front, especially if you're trying to maintain a decent posture.

First, unfortunately, is my normal posture, followed by a more normal healthy position. I'm hoping these movements will help stretch and strengthen the deep muscles in my upper back near the spine.
