Importance of Proper Weight Training Form

To get the most out of your weight training routine you MUST use proper form on your exercises.
There is nothing worse than glancing over to see someone with poor form.
When you compromise on form, you also may not be targeting that specific muscle group you set out to work.  Using too much weight and not getting full reps won't work your muscles as efficiently either.
Getting the most from weight lifting requires proper form, controlled movements and the right amount of weight. Lifting weights that are too heavy for you is a set-up for injury. If you can't maintain proper form while lifting, the weights are too heavy for you.
