Behind the Back Eccentric
1.) Start with a light band tied around a squat rack or other sturdy, immovable object
2.) Grab the end of the band with your palm facing away from your back
3.) Rest your opposite hand on top of your opposite shoulder
4.) Keeping your shoulder level sweep sweep the back of your hand across the small of your back from one hip to the other
5.) Return to the start position SLOWLY - this should be an eccentric movement
