The XMark Commercial Vertical Knee Raise with Dip Station and Push Up Station will provide defined abs, stronger arms, a well-developed chest and strong back. While the vertical knee raise station targets your core and abs, the push-up station focuses on your chest. Twin dip handles are ergonomically spaced to help give a great dip workout to strengthen arms and shoulders. Simple, basic, rugged and, most of all, effective, the XM-4437.2 vertical knee raise is a commercial unit yet ideal for your home gym. This upgraded version features commercial gym-quality cushions and rubber grips which cover the complete push-up handles.
