The only negative aspect of this machine was the instructions. They took what should have been an easy and straightforward process and made it unnecessarily confusing. Referenced part numbers and details simply did not match with what was included, in some cases did not even match with other parts of the instructions, and some things (like the foot stand) were entirely omitted from the setup instructions. It's not a complicated thing to put together but it should have been so much easier. The only advantage I can see for having the instructions only be online and not included with the machine is so that Ironmaster has the opportunity to fix any errors and have the correct instructions for the specific version of the machine/included parts, so it's disappointing that none of that happened. That aside - I love this thing. After a short settling-in period where I figured out how to best place my feet and shoulders, I was able to cook my glutes and quads more than I ever. Placed a large rubber block right behind it so I can do sort of Bulgarian Split Squats, with no need to focus on not falling over I was able to get an incredible workout. Love it! Just.... do better with the instructions please!
