Designed for professional training, the Hydrofoil board is a streamlined, ergonomic update to the classic board. Its lower overall height and longer surface help create a natural, unrestricted training experience for high-level swimmers. The LHYDPF is an ideal training aid for strengthening; it lifts the body to help develop upper-body strength and proper technique. Designed to be placed between the legs, the Hydrofoil Pull Float helps swimmers focus on arm movement and technique by isolating the legs and eliminating kicking.
