a relatively light weight held close to your body won t have a radical effect on your muscles but if you place that weight a long way from your centre of gravity then the effects can really start to be noticeable. these weighted gloves have a super quick on/off design so that they are comfortable and at the same time practical. the soft material gives you a close fit but also ensures that you can use your hands freely at any time which means that you can keep them on whilst changing the volume on your iPod® or tying up your shoe laces.2 x 0.5kg integrated weight. breathable material for maximum comfort. Velcro closure and ring pull for easy removal.
