A support for an exercise device includes a frame having a top, a bottom,
and two lateral sides extending between the top and the bottom. The frame
has a channel defined about an interior perimeter. The top, the bottom
and the two lateral sides define an opening. The frame has a body support
integrally formed with the frame. The body support is formed by a lower
arcuate portion of each of the two lateral sides. A membrane is
operatively connected to a carrier. The carrier is adapted to attach to
the frame via the channel, and the membrane having a first side and a
second side.
