In my experience, the description for the GHD is misleading and inaccurate for what I was expecting. Vulcan's product description states : "Fully adjustable dual pads with a slight angle. Easy pull pin and dual bearing slider for quick adjustment. Will accommodate any user 5ft to 7ft. Every feature that could be wanted in a GHD (Glute Hamstring Developer) has been incorporated into the Vulcan Glute Ham Developer" I found this machine to be tremendously difficult to adjust. The pull pins are not easy, they are basic screws that you have to completely untwist and remove, then use two hands to move the foot rollers/ down separately, completely guessing if you line up with a hole as you can't see due to the plastic rectangle holder, then try to re-screw the pin in--while still holding the roller in position. It's a 10-minute juggling process to try and get the correct setting. The dual bearing feels impossible to adjust. I'm 5'4'' 112 lbs and have to completely stand behind the machine, lean in, and push as if I'm doing a sled push to adjust the length. Then, need to repeat the guess and check process lining up the screw with the hole. The fixed crescent moon pads do not accommodate a smaller athlete. They go beyond the distance of my hip/pelvis to my ribs, limiting me from being able to do a full rep at 90 degrees- barely able to fold forward 30 degrees. The fixed roundness and size completely limit the range of motion. I tried fixing this by adjusting the length, but it either puts harmful pressure on my knees or above my ribs-- Leaving my hips unsupported and unable to engage the muscles properly. I feel this purchase was a complete waste of $599 for me. The description set an expectation that this could work for glute ham and hyperextension exercises, which is not the case for me. Unfortunately, the return policy results in losing more than half of what I paid after return shipping and the 20% restocking fee. The customer service team does not answer the phone and takes 3 business days to answer an email. I will not buy from Vulcan again and would not recommend their products to anyone.
