Sit or stand at the head-end of the Allegro, and use spring resistance for pulling rather than pushing. Great for spinal mobilization, as in Seated Cat or Merrmaid, or to increase inner thigh work for standing exercises by pulling the carriage towards you. Pilates instructors world-wide offer Balanced Body ideas for new products. Add-a-Platform(TM) is a result of our wonderful collaborative process. Fits any Allegro Reformer, with or without a Tower.
