One of the most common issues I see in the clinic with active exercise enthusiasts between the age of 20 and 55 is shoulder pain. Weightlifting has been popular for ages, but Crossfit is all the rage these days.  Both disciplines involve overhead lifts. The key thing to remember when performing overhead repetitive lifts is how load and stress not only affects strength and power, but how it impacts the joint itself.

Pull-ups and pull-downs are staples for most clients I see.  As a therapist and strength coach, I am always thinking and analyzing how variables such as grip, grip width, arm position, scapular activation, trunk angles etc influence exercise and how force is absorbed by the body.  One such exercise I have spent time studying and tweaking is the lat pull-down.

Consider for a moment how width and grip impacts the relative abduction and horizontal external rotation in the shoulder at the top and bottom of the movement in the pictures below (start and finish positions are vertically oriented):

It should be common knowledge for most, but I will state it for the record anyway – you should NEVER do behind the neck pull-downs.  Beyond the horrible neck position, this places the shoulder in a dangerous position for impingement and excessively stresses the anterior shoulder capsule.  A wider grip (be it with pull-ups, pull downs, push-ups) will always transfer more stress to the shoulder joint because you have a longer lever and greater abduction and horizontal external rotation.

So, what bearing does this have in relation to the rotator cuff and SLAP injuries?  For more information and details on the application of the grip choice, click here to read the full column I did for PFP Magazine this month.  Stay tuned for my next post (a follow-up to this one) one of my Crossfit patients who now only has pain with overhead squats and how my differential diagnosis and rehab has led me to conclude what is wrong with his shoulder.  Keep in mind we must learn to train smarter so we can train harder and longer without pain and injury.  Biomechanics and understanding your own body really does matter.
