Abstract
In exercise apparatus for underwater use including an apparatus frame, and movable members mounted on the frame to be moved by a user of the apparatus, flap members, e.g., flat plates, are mounted on the movable members for movement therewith within the surrounding water. The water resists movement of the flap means, hence provides resistance to movement of the members moved by the user. Disclosed are apparatus which, in use, simulate the movements of a cross-country skier, an ice-skating speed racer, and a rower of a row boat. Arrangements are also disclosed for selectively varying the resistance to movement provided by the flap members in response to the direction of movement of the movable members. All exercises with equipment embodying the invention can be performed with all of the user's body and limbs being submerged in water in order to decrease strains on the user's joints, thereby providing an exercise mechanism which incorporates high resistance to the user's muscles with low impact on the user's joints.
