Mistake: Standing too upright during the backhand low serve with a high 149.4° knee angle.
Fix: Bend your knees slightly to drop your center of gravity before starting the service motion.
Why it matters: A stiff, upright stance reduces lower-body stability, making it harder to control the trajectory and height of the low serve over the net tape.
Drills
- Mirror serve stance drill: set up with a 110-120° knee bend and check stance before serving
