Our 25' Speed Cords are our workhorse cords that can do it all. They can be doubled around a person or goal post for double resistance for shorter distance movements up to 12 yds, or lengthened to full length for drills 25 or more yds. We use these cords more than any other product due to the versatility and limitless configurations that can be achieved. These cords work great with our "H" Harness and 360 Belts, and can also be added to our Punch Belt and Pro Punch Belts. Each cord comes with a protective sheathing and light, medium, and heavy resistance levels.
