The Kneeling Drill and the X Factor Stretch

The X Factor stretch is a key component to increasing club head speed but it can also leave you with some sore lower back if you're not swinging with the correct mechanics. Kneeing drills will help gain some mobility in your hips and allow the muscles to lengthen a little bit more, which helps release power. You don't want to increase the X Factor stretch too much because bombing it every day could be harmful for your lumbar vertebrae.
