Abstract
The Pilates chair exercise device includes a frame configured to rest on a horizontal plane, an inverted Y-shaped seat support fastened to the upper surface of the frame, a seat fastened to the upper end of the seat support, and a pair of parallel arms each having a proximal end fastened to the frame and a foot support fastened to the distal end of the arm, wherein each arm is biased away from the frame toward the seat. A rotary torque unit attached to the frame below the seat biases each of the arms. The rotary torque unit includes a rotary spring cassette carrying a plurality of flat coil springs, each having only one end fastened to the shaft at one end of one of the arms. The combination of springs in the spring cassette may be selected by the user without the user leaving the seat of the chair exercise device.
