Connect a resistance band to the workout bar and attach the other end to a D-ring on an ankle strap. Do the same for a pair of resistance bands. Stand holding the workout bar using an overhand or a mixed grip. Grip should be shoulder width or slightly wider.
Elevate shoulders (upwards shrug) as high as possible.Lower and repeat.
Since this movement becomes more difficult as full shoulder elevation is achieved, height criteria for shoulder elevation may be needed. For example, raising shoulders until slope of shoulders become horizontal may be considered adequate depending upon individual body structure.
