Standing in between the front of the handles, hinge forward and grab both handles. Then hinge back up to have a straight neutral spine.

Start by squeezing your shoulders and raising them as high as comfortable, then briefly pause at the top before slowly lowering your shoulders back down to the starting position. Raise your shoulders in a consistent and controlled manner straight upwards as you look forward. Repeat for the desired amount of repetitions.

Avoid using momentum, dropping your shoulders down without control.
