HOW: Place a very light superband over the barbell. Use both of your feet to keep the band on the ground. Keeping your core engaged and using just one arm, slowly push the barbell above you. The higher you lift you arm, the more tension there is on the band and the harder the exercise will feel.
FEEL: You should feel all the muscles in your shoulders and mid back working. You will also feel your core muscles working to maintain your position.
COMPENSATION: The goal of this exercise is not to use momentum. Try to only use your shoulder muscles to do the lift!
