Query: Enlightening video that really helps get results

In my opinion, this video is as close as you can get to having a personal trainer without actually having to pay for one. Raphael Picaud gives you excellent tips and demonstrations on how to properly weight train. For most people who don't know much about form or technique this video will be quite enlightening. I thought I knew how to lift weights (seems simple enough, right?), but I never really got the results I wanted. After watching this video, I put the techniques to use and I got excellent results, quite immediately. It's also great for preventing injuries and muscle strain. I highly recommend this video for anyone who wants to learn how to work out the right way.
