The TYR Pull Float swim board was designed for strength-building and aquatic exercises. An ideal training aid for swimmers of all levels, the LPF increases resistance and weight in the water to help develop upper-body strength and proper technique. Placed between the legs, the Pull Float helps swimmers focus on arm movement and technique by isolating the legs and taking them out of the movement. Made of 6-inch EVA foam, the Pull Float board was designed for long-lasting use and performance in the water.
