Butterfly Zipper Drill - Traditional Technique

This clip, featuring GDI student Colin Catherman and his skating coach Helena Nyman, illustrates the Butterfly Zipper Drill, alternating diagonal butterfly movement forwards and backwards, using traditional techniques. Each time Colin moves, he rotates his hips and shoulders over his knees, plants his backside skate at the desired angle with his leg loaded, and pushes more or less straight through (at 90-degrees to) the blade. Sound technique is shown throughout, though power, precision, and fluidity are somewhat lacking.
