Only lifts in the 70-80 % range have meaningful value for them. They use it every training.

TL;DR

mobile work station that uses the Microsoft Kinect camera system

they collect 3d data, and build a database for each lifter

used in training and competitions

it gives real time measurement, instant feedback

Video

Here is a quick video showing it in use.



Things it Measures

bar path

bar height (in meters, % of body height)

bar velocity

bar acceleration

horizontal bar displacement

minimum height required to make the lift

all values are real-time and synchronized with the video

comparison of lifts
