I just stumbled upon a website for a Vancouver personal trainer that seems like a world class dumbass. Here’s a question and answer from his FAQ page (the awful grammar and punctuation is his):

Q2. Is there a Wrong Way to workout ??

A2. No there is No wrong way to work out but there is a right way. It Can cause you problems if you are training the wrong way but it is still beneficial to workout incorrectly than not at all. Learning the right way to Workout in Vancouver at Home or Work, Will help you get the results you want in 6 weeks rather than 6 months with less risk of injury.

What an unbelievably stupid moron that guy is. Of course there are wrong ways to exercise. In some cases there are extremely wrong ways to workout. Any fitness professional who says otherwise is a dangerous fool.
