Great hyperextension. The reason was why I chose this one over the competitors in this price range was the 600lb weight capacity which is double compared to everyone else's. It is a solid unit! My only complaints are the quality control. One of the end caps for the feet was so warped it too about a half hour to get on. Also one of the cushions the foam pad was split under the uppolstey. Not sure if it got torn while be upholstered or of the used two pieces of foam to make the wrap around. Does not effect the function of the bench. The shipping packaging was great and packed well. No damage to the box. Am satisfied with the bench.
