2 x 2 x 11 Gauge Frame
For Quads/Hamstrings
Custom Colors

BOMB PROOF® Plate Loaded Leg Extension / Leg Curl Combo - The BP-21 American Made Leg Extension / Leg Curl Combo is a commercial grade strength training machine built for heavy-duty use in commercial gyms. By simply lying on the stomach, the BP-21 quickly and easily converts from a seated leg extension to lying leg curl and vice versa. The BP-21 excels in facilities with limited floorspace and allows users to fully train the quadriceps and hamstrings in a foot print of only 65 x 28. To ensure solid performance under heavy payloads, the commercial quality steel frame is fabricated from 2 x 2 x 11 gauge tubing that is both mig-welded and fastened with high grade hardware. Densely padded rollers are adjustable as much as 5 via pop-pin in 1 increments to accommodate users of different heights making sure that each roller is properly aligned with the front of the shin and back of the calf. And to keep users stable during both leg extensions and leg curls, there are two sets of handles. Choose your favorite powder coat and vinyl colors per the drop down menu at no extra charge.
