Focus on keeping your legs together and jumping vertically straight up under the ball, lining yourself up directly below the contact point, rather than moving forward or sideways.
This covers a neat way to think about your smash. The coach uses a simple visual cue, the Mario pipe, to help you focus on jumping straight up instead of forward or sideways. This can really help you make contact higher and get more power and direction on your overhead shots. It addresses a common mistake and provides a clear correction.
