Pro‑serve secret: a 20° elbow squeeze (≈90° → ≈70°) during leg drive unlocks that down‑then‑up whip every top player uses.
Most players freeze the joint and lose 10+ mph. Could you feel this 0.14‑s window on your own?

Pro‑level serve power comes from 3 exact elbow angles. 🎯

1️⃣ Set behind/in‑line with shoulders
2️⃣ Keep height around shoulder‑level
3️⃣ Hold ~90° — not open or collapsed

Our AI flags when you’re off by degrees—just like the overlay you saw on Alcaraz.
Does your serve feel most limited by height/angle?

Land on the balls of your feet for a serve that protects your knees.
Your calf absorbs the impact and springs you into your split step — that’s why Alcaraz moves so fast.

Djokovic sometimes heels on kick serves, but for most players, ball‑of‑foot is the safer, faster default.

When my AI whistles, your stance is perfect. 🎯
It tracks hips, knees, & ankles to mirror Alcaraz + Sinner’s serve form—giving instant audio feedback for true pinpoint balance.

Notice faster timing + smoother contact?

Put your elbow here and your racquet flips itself.
After your unit turn, draw the elbow back, then extend it straight—ending with your arm by your hip and the racquet tip at ~5:30.
That’s how Djokovic‑style power and spin become automatic.

Toss too far “out” on serve? Try this pro cue:
Release = 12 o’clock → send the ball ~30 min inside your body line (R→L / L→R).
More balance, less reach, effortless power.

Most club players skip Djokovic’s 45° backswing checkpoint 👀🎾
Right arm = light abduction + elbow extension.
Elbow lines with shoulders; racquet tip up, strings slightly down → effortless power.
Try it in slo‑mo.
