Core Product Lines

• StrechCordz® Stationary Swim Trainers: High-quality elastic cords — including the popular S121 model — designed for in-place swimming. Ideal for maximizing training in smaller home pools, swim spas, or limited-space environments.
• Safety Short Belts & Sliders: Color-coded resistance tethers ranging from 8 lbs to 45 lbs of pull strength, allowing swimmers to train at the resistance level that matches their ability and goals.
• Dry-Land Cords: Resistance bands fitted with specialized paddles or handles to replicate a true swimming pull motion out of the water — perfect for dryland training programs and strength conditioning.

Whether you're training in a full-size competition pool, a backyard swim spa, or on dry land, NZ Manufacturing's StrechCordz® system delivers a complete resistance training solution. Shop the collection at Swim2000 and take your swim training to the next level.
