Pilates Reformer Equipment 

The reformer offers overall strength, flexibility, coordination, and balance.  The instability of a rolling carriage with springs set at different levels of resistance provides all kinds of stability challenges that develop core strength and promote better balance.  The pushing and pulling with legs or arms against the resistance of the springs, carriage and body weight is strength building.  A special feature called eccentric muscle contractions happens when the muscle lengthens as it resists a force - that is one of the keys to achieving the long, strong muscles without bulk that Pilates is known for.
