A device and method for swimmers to enhance propulsion from the swimmer's kick. The device resists flexure of the swimmer's knees by providing a first band secured typically to the thigh, a second band secured typically to the lower leg, and a flexurally resistant member coupled to the first and second bands. By resisting knee flexure, the swimmer is forced to power a flutter kick with hip muscles rather than leg muscles, resulting in a generally more powerful and efficient flutter kick. In one embodiment, the bands secured to the legs may include Velcro TM for a snug ift. Also, the flexurally resistant member by comprise a graphite or fiberglass rod. A sliding member, such as a ring around the flexurally resistant member, may be provided with a line to prevent loss of a detached flexurally resistant member. Also, the flexurally resistant member may be snapped into fittings for quick assembly or release. The device may be attached to the lower leg by a swim fin adapted to be worn on the swimmer's foot. The device may be attached to the thigh by the upper band being attached to an underwater diver's suit pants. The flexurally resistant member may include first and second segments, and a locking mechanism for selectively having the member in a locked mode to resist bending or in an unlocked mode.
