HOW: Get set-up seated and assume a slump position by letting your upper body round and slump forward. While maintaining this position, kick your leg straight and point your foot down as you simultaneously look up with your head and neck. Reverse the motion back to starting position and repeat.
FEEL: You may feel a stretch and a pull from your low back all the way to your foot on the side you're kicking, if you get significant numbness and tingling or pins and needles or you already have these symptoms and they get exacerbated, back off and don’t kick as far.
COMPENSATION: Maintain the slump position, keep both leg and head movements happening at the same time, don't move too fast. Do not point your foot up, that is a different nerve exercise.
