Solid construction + simple assembly

The TuffStuff Hyper-Extension bench is solidly constructed (able to withhold up to 400 lbs. including the user's bodyweight) and is very easy to assemble. It offers a variety of angles and comfortably anchors the feet in a secure position. Assembly instructions were not included in the package but are downloadable in PDF format. Roller wheels at the foot of the bench allow it to be maneuvered easily which is especially convenient for smaller home gym settings. Highly recommended for those requiring a solid, hyper-extension bench that can handle additional weight.
