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. Grab the workout bar using an overhand grip with elbows straight or slightly bent. Stand and hold the bar whilst keeping arms straight.
Raise the workout bar forwards and upwards until upper arms are above horizontal. Lower and repeat.
Absolute height of movement may depend on range of motion. Raise should be limited to height achieved just before tightness is felt in the shoulder capsule. Alternatively, height just above horizontal may be considered adequate. Elbows may be kept straight or slightly bent throughout movement.
