The Cybex Eagle NX calf is a top-of-the-range piece of gym equipment that is made to promote natural movement so you work out safely & comfortably for the best results. The seated exercise focusses on the legs & in particular the calf muscles & the machine is designed so that spinal compression is minimised & forces are directed through the user's hips rather than shoulders. The footplate is curved, training the mid-foot to take the load which gives better results, & it comes with a 184kg (405lbs) weight stack, instructive placards & some useful accessory holders.
