Leg Raise on the Exercise Ball 3
(arms straight up)

Starting Position	Start this ball exercise by sitting on the ball with a neutral lumbar posture. (How to Sit) Chest should be up, shoulder blades down and back, and head back over your shoulders. Keep your feet flat on the ground shoulder width or slightly further apart. Raise your arms up straight as high as you can.
Action	Using a slow and controlled movement, raise your foot off the floor while straightening your knee. This reduces the points of stable contact to 1. Maintain a neutral spinal position and don't lean back.
Prime Movers	Quadriceps
Physio Tips	If you find yourself wobbling around go back and try the Seated Leg Raise 1 (hands on hips) Concentrate more on maintaining transversus abdominus activity, keeping a level pelvis. Start with small movements until your are comfortable. If trying this exercise with your eyes closed be sure to make safety a priority.
Progression	Try Seated Leg Raise (arms up) with your eyes closed for more of a balance and proprioceptive challenge.
