You say that like its a bad thing. I busted my back yesterday at the gym with improper form on a dead lift. If I had some kind of assistant watching me to correct my form then I would not be eating pain killers now trying to get an appointment to see a doctor all while having tingling sensations in my feet.

Someone's building a product for this: https://www.indiegogo.com/projects/biometrix-an-evolution-in...

The difference is requesting it or not.

You should probably work with a trainer until your form is correct.
