The Wall Walk and the Modified Wall Walk begin in exactly the same way. Once the feet are on the wall the weight is transferred through the hands. Stack the shoulders and wrist as much as you can over each other before attempting to stack the hips. Once everything is off the ground walk yourself up the wall. Make sure to maintain your balance and actively drive through the shoulders. ideally the hips, shoulders and wrists will all be in a single line To keep the midline intact squeeze your butt and abs to form a solid core. This will allow you to have a flat back while at the top of the movement.
When you’re ready to come down, under control walk yourself out.
