PROIRON 0.5kg Ankle weights have a segmented design for supreme comfort whether worn on the wrist or ankles. The adjustable Velcro strap is easy to adjust and ensures the weights are tight and will not move during use. Premium iron sand is spread evenly and held in place by reinforced stitching. The soft and breathable material is soft to the skin and will not cause irritation. Reflective trims make running in low light levels a bit safer. Supplied as a pair and suitable for wrists and ankles. The principle behind wrist and ankle weights is simple - adding extra weight to your body makes your muscles work more and helps you to burn off extra calories without even realising it! You don\'t need to do anything differently to what you normally do - that\'s the beauty of them! Our ankle weight sets are perfect for adding intensity to yoga, gymnastics, and Pilates, and can be used as wrist weights. They will build muscle, improve balance and flexibility, and can be used for physical therapy. T
