Designed for resistance and speed-assisted swim training, the 30' (10m) Swim Belt tube is design to stretch to 75' (25m). The length and tension of the tether can also be varied to supply the desired amount of resistance by adjusting the size of the tubing loop. Speed-assist swims are great for finding your best streamline positions and for fast, high turn-over swims (without full exertion) during the taper phase of the workout.

• Great for IM training
• A reversing tether ring on the swimmer's belt allows for directional changes without stopping
• Resistance swims are great for strength work early in the season
