Fortress wrist and ankle cuff weights are soft weighted cuffs that strap around the wrist or the ankle so that resistance can be added to an exercise without having to grip anything. The cuff wraps around the limb and fastens with a long hook-and-loop extension strap, which allows the same weight to fit a slim wrist or a larger ankle and to stay put through a full movement. Each cuff is covered in heavy duty coated vinyl, so it wipes clean between users and stands up to repeated handling. The weight is marked in both pounds and kilograms, and the range runs from 500 g up to 10 kg, with each weight in its own colour so the right one can be picked out at a glance. Cuffs are sold individually rather than in pairs.

Being able to add resistance without gripping makes these cuffs useful for people whose hands are the limiting factor, and for exercises where the hands need to stay free. The long extension strap means one cuff suits both wrists and ankles and a range of limb sizes, and the colour coding makes it easy to follow a program that steps up in small increments.
