Laser barbell technology

Unlike any other barbell sensor or barbell accelerometer, FLEX uses a laser optic array technology. This is a wireless, accurate and durable barbell tracking solution.

In fact, this barbell technology makes FLEX the most accurate bar speed measuring device under USD $500. It measures every rep and is extremely accurate at both high and low speeds.
