To execute an effective kick serve, two technical keys are essential:
Upper back extension (thoracic spine):
You need to arch your upper back so you can strike the ball above — or even slightly behind — your head. That’s what gives the ball that signature “kick” spin that drives opponents crazy.
Proper racquet drop:
A smooth and powerful racquet drop requires good external shoulder rotation. This creates the space you need for a fast, upward whip.
But be careful!
Many players — especially juniors — compensate the wrong way: instead of extending the upper back, they over-arch the lower back.
Result?
Back pain, overload, and avoidable injuries.
For young athletes in particular, protecting the lumbar spine is crucial.
The secret?
Train thoracic mobility, focus on posture, and learn to separate proper upper extension from harmful lower back hyperextension.
“Power is nothing without control.”
— And yes, that applies to the kick serve too!
If you'd like, I can send you a specific training guide with thoracic mobility drills to help improve your serve and protect your spine. Just let me know!
