I just read a great q & a about the "Big 3" core stability exercises according to Stuart McGill. I have studied his books and followed his research for years and am excited to hear more and more about him in the media. It's a good read and you'll learn about some causes of lower back pain and how the "Big 3" help to alleviate it. Have a good one!
