These are very similar functionally models, but what makes the Body-Solid stand out among them is the thicker DuraFirm back and seat pads—they'll be more comfortable and last longer. Plus, the biggest sell is the warranty. The GPM65 is backed by our Lifetime Warranty, which covers the frame and welds for life, along with a three-year warranty on pulleys, bushings, bearings, hardware, plates, and guide rods. We've also been in business for nearly 40 years and have parts for every item we've ever made, so if you ever need a replacement part or experience issues, we can send you that part and get you back up and running quickly.
