Squatmate - for better squatting.

The Squatmate^® concept:

at your chosen squat depth your rear breaks an infrared beam, activating an audible signal.

when you reach your chosen squat depth, the Squatmate buzzes
adjustable for height from 7" (17.5 cm) to 15" (37.5 cm), in 1" (2.5 cm) increments
avoids the risk of squatting onto a bench
eliminates doubt about squat depth
allows you to optimise your squat routine, e.g. squat to different depths with consistency
