~ Stand with feet fairly narrow, toes pointing forwards.
~ Let arms hang down by side of body.
~ Lift one foot off the ground so all your weight is on a single side.
~ Notice what happens; is there movement in your upper body while hips down seem fairly stable? Can you feel your core muscles activate?
~ Perform test 3 times on each side to get an average, and see if you're similarly good on right and left!
~ Watch back recording and look for any compensations; mark down your findings using the checklist below.
