The variety of exercises alone is far superior in reformer pilates. Reformer pilates works on core stabilisation, just like mat pilates, except it uses your legs and arms more effectively, and is therefore more appealing in helping your rehabilitation and sport-specific training.
Reformer pilates promotes endurance, joint stability, muscle strength and tone, balance and proprioception. Patients who may not be able to perform a weight-bearing (standing) movement can lay down on the reformer and use the springs as resistance to achieve strength and mobility gains for the same muscle groups.
