About Us

NZ began their journey in 1985 producing the highest quality resistive exercise products for swim training, physical rehabilitation, sports training and general fitness.

The StrechCordz® line of swim training products was designed by a group of competitive swimmers to improve stroke, endurance and strength. From in-water swimming tethers, spa tethers and grudge belts to dry-land resistance training products they fit the need for any serious as well as novice swimmer. We are now offering an expanded StrechCordz line which includes educational products and enhancements to our existing products for additional safety, comfort and performance.

MediCordz® products are the result of numerous requests by therapists and patients for a product line designed for maximum function and comfort at a reasonable cost. MediCordz products accommodate all major joints and muscle groups to fulfill virtually any rehabilitation need. New this year is our Safety Bungie; a unique patent pending product designed specifically for safety and security.

TurfCordz products are used in high level athletic training. Used by leading professional football, baseball, hockey and basketball teams for explosive startdrills, power building footwork exercises and simulated play action. Our new TurfCordz Safety Cord Tubing now includes a Safety Cord insert for additional strength and reliability.
