These are the low-profile wearable weights that discreetly fit under clothing, providing extra calorie burning during normal daily activity. Unlike bulky ankle weights, these distribute weight equally over a larger surface area, freeing ankles and wrists from stress while providing resistance. Worn while performing household tasks such as cleaning, walking a dog, or working at a desk, the added resistance helps to burn more calories. The weights are comprised of 1" sq. x 1/8" thick galvanized steel plates sewn into a soft nylon/spandex sleeve that secures to extremities using hook-loop-fasteners. Non-slip cuffs on the inside of each opening keeps sleeves from slipping down a leg or arm. Calf Weights. Size XL (16-18") (5 lbs. ea.)
