Sit to Stand exercise.  This week’s exercise will test your core muscles, adductors and glutes not to mention, work a particularly important functional movement.   You can do this from a chair, bench or Swiss Ball.  Place a ball (medicine ball or yoga ball) between your knees.  From a seated position, hands behind the head stand up keeping the ball securely positioned between the knees.  Sit back down without letting go of the ball.  Keep your hips well behind your heels.  Next week will demonstrate a more advanced exercise.  Do 2-3 sets of 10-15 reps.
