Double stitched Ab slings from CYBERFIT™, complete with bar hangers. Perfect for hanging knee raise. With hanging knee raise slings you can really torch those abdominals and tighten the abdominal wall for a flatter stomach.
Ab slings provide the support you need to keep your upper body stable while doing knee raises. The upper arms are supported and essentially 'pinned' to the chinup bar, keeping the upper body still, and the result is a far better burn and better results! They also help take the load off the spine, so those with back problems will find these things a miracle cure!
Heavy duty 10,000lb carabiners support every body, large or small
