How do they test this technology? Where do they get the people to test on? How large was the test group? How about group diversity? (Children, elderly, pregnant women, people suffering from epilepsy, heart disease, etc)? Have the test results been validated by a third party? Ah, the list goes on and on.
I read a discussion on Usenet many years ago about squats in weight training.
A post described how they measured the stomach muscles' pressure on intestines. Someone asked "How do they get anyone to do heavy squats with a pressure sensor up their ass?!"
