Abstract: The exercise apparatus for swimmers has a ground-engaging base frame supporting a front section supporting the chest and arms, a central section supporting the torso, and a rear section supporting the legs. The base frame is made of square tubing and includes a forward portion on which the front section is slidably mounted and a rear portion on which the central and rear sections are mounted, the forward and rear portions being connected by a screw drive to adjust axial length of the apparatus. The front chest support section includes a resilient telescoping post having chest pads mounted thereon and a cross member having adjustable lateral arm posts. The central torso support section includes a resilient telescoping post having torso pads mounted thereon. The rear section includes a post on which leg supports are mounted. The apparatus may be configured for freestyle strokes or breast strokes.
