Setup

  1. Back flat on the pad, shoulders under the pads.
  2. Feet mid-platform, hip-width.

How To Do It

  1. Lower under control until thighs pass parallel.
  2. Keep the whole foot pressing; knees track over toes.
  3. Drive up without slamming into lockout.

Breathing

Inhale down, exhale through the drive.

Common Mistakes

  • Feet too low on the platform — knees take over everything; move them up.
  • Bouncing the bottom — pause a beat instead.
Coach Sam's cue: Ride the rails down slow, push the platform away fast.
