These strong, reliable resistance bands come highly recommended by health professionals. They enable you to gently regain fitness in weak and injured muscles. The accessory pack helps make exercising more comfortable and effective as well as increasing the number of exercises you can perform. Anyone who's used resistance bands will recognise that they can take a little bit of getting used to. Many exercises require you to tie the band in a knot, hook it over your foot or loop it around a chair or banister. This is do-able but not always easy, especially for people with painful fingers, reduced mobility or a weak grip. With the accessory pack you can stop the band twanging out of position by using the clip to clamp it at the length you need or the Assist Strap to attach it to the chair or bannister. The wrist cuff and comfortable handle to make gripping easier so you won't accidentally lose your grasp on the band.
