The exercise machines dedicated to leg extension are usually big and take up the much-needed training space. We wanted to make an alternative, space-saving option with the same function. This is how our Mighty Rack Leg Extension accessory came to life. It is quickly and easily attachable to your Mighty Rig or Rack with just one pin bolt. The leg holders are upholstered with memory foam and PU leather for optimal comfort. The Mighty Rack Leg Extension is plate loaded, which means that you can use any standard plates with a 50mm hole diameter to add weight to your leg extension training.
