  1. 1Lats and core driving the ball down with force
  2. 2A hard abdominal contraction as you fold forward
  3. 3Full overhead stretch before each slam

Common mistakes

  • Slamming with only your arms instead of your trunk
  • Rounding sharply at the lower back on the catch
  • Letting the ball drift away so you lose control
