One Back Exercise Keeps Me 90% Well

My progress is excellent.

I started doing all your back exercises, but now I have gotten down to the key one that keeps me 90% well: the backward bend.

I had been doing a lot of forward bends, thinking in the past that it would stretch out everything. From your e-book I learned that the backward bend opens up and allows the disks to decompress. So when I get out of bed in the morning I immediately do a few backward bends, and a forward bend.

The result is that I am no longer wearing a lumbar support, and am able to easily do my carpentry work.

Last week I had to carry 8 -  80 pound bags of concrete, mix it with a hoe, and shovel it all into holes in the ground for footings
I HAD NO PROBLEMS AT ALL

Thanks
