Biomechanical Swing Trainer – Instant Click Feedback, Adjustable Weight & Resistance, for Tennis

Product Overview
The first biomechanical training tool that brings the real swing experience off the court. Pure mechanical feedback – no electronics, no sensors. 

Key Features

🎾 Instant mechanical click feedback
Inside the tube, a sliding mass hits the stop at peak acceleration. The click simulates ball impact – you hear and feel when your timing is right.

💨 Adjustable pneumatic resistance
Two resistance levels: light for fluidity and coordination, high for muscle activation and strength training.

⚙️ Customizable weight & balance
5 micro‑weights (17g each). Place them at the head for power or the butt cap for control. Total weight from 390g to 474g.

🌍 Train anywhere – home, gym, locker room
Compact and fully mechanical. No court needed. Use for warm‑ups, technique drills, or low‑impact strength work. Silent, simple, always ready.
