Now that my shoulders and hips are finally getting some good mobility, I'm able to do this Founder exercise. It's really good for your posture. I like it a lot. The Dr. points out that about 80% of people these days have forward posture. Most people here probably do. I like this guy he makes a lot of sense and notice how good his posture is.
