Exercise balls are one of today's top fitness tools - and for good reason! Using an exercise ball will improve the strength of the abs and the lower back. Since the exercise ball is unstable you have to constantly adjust your balance, which in turn will improve your balance and flexibility.
Macdonald’s Prescriptions carries a wide range of Exercise balls, available in all different sizes.
Regular prices range from $39.99 to $59.99.
Just think, at a 20% discount, you could walk away with a stronger lower back and a six-pack for under $50.00!
