God is so good to us, it's unbelievable... at least to some. Incredible.
I got a Total Gym type machine also. It's great low impact workouts that gives a good stretch. A lot of times I just put it on the highest setting and hook my feet up and hang, to decompress my spine at the end of the day. Feels great.
