Corey performing the American Kettle Bell swing well with fulling extended hips, maintained midline with elbows extended and kettle bell vertical overhead. Two things to avoid in the American Kettlebell Swing are rebounding the hips and lifting the rib cage. To prevent these think about the hip to shoulder action of a push press where you will initiate the movement at the hips, brace through the midline and finish with the arms avoiding the double dip seen in a push jerk.
