Engineering studies.... A recent study on the Power Plate..... Measured Power Plate unloaded at the same settings compared to being loaded with 85 kg, 110 Kg, and above 110 Kg. Power Plate lost 1 mm in amplitude from unloaded compared to loaded with 85 kg and really bogged down at 110 kg and above.
Note: These figures are comparable to failed tests done in 2005.
Here is a good visual tests non-engineers can do to see if a machine is doing it job regardless of who is on it .... http://www.youtube.com/user/VibraTrain# ... i_Dxunqpro
It would be great to see these kinds of tests to become standard to protect the consumer.
