Starting today, I'll be sharing here on my blog a series of articles showing the proper techniques for weight training exercises. The title of these articles are going to be “Do It Right” and the first one is the Lat Pull-Down exercise.
DO IT RIGHT – THE LAT PULL-DOWN EXERCISE

THE BEHIND THE NECK LAT PULL- DOWN
The myth: The best way to perform the Lat Pull-Down is to pull the bar behind your head, down to your upper back.
The truth: Unless you have very flexible shoulders, this exercise is difficult to do correctly, and can increase your risk for shoulder impingement syndrome, a painful condition in which the muscles or tendons of your rotator cuff become entrapped in your shoulder joint.
The alternative: Simple, just pull the bar in front of your head, down to your collarbone. You’ll work your back just as hard, but with less risk for injury.
