Punch Back Drill for Yurchenko Vaults
Danelle Catlett of Soild Rock Gymnastics explains a great vault drill to work on the preflight of a Yurchenko vault. The goal of the drill is to teach gymnasts to not throw their arms early back to the horse, which many coaches see happening often. All you need is a big resi mat propped up with a panel mat in front of it and you've got a perfect set up for teaching the proper arm position on Yurchenkos.
