Question: does the top pulldown swivel, or is it fixed? thanks
Document: I needed a lat pulldown machine that would also allow me to do various rowing exercises yet was compact enough to fit in my home gym. While I was not looking for pro gym quality, I did want something very well built as I work out six days a week religiously. With respect to this machine, I needed something that would stand up to regular use twice per week. While I have only had the machine for a week now I can tell that it is exactly what I was looking for.
You can't install all the pulleys and then feed the cables last. You need to feed the cables and install the pulleys as you go along.My impressions are as follows:Pluses: For the low price you get a lat pull down machine without a weight stack that can perform several exercises: lat pull downs, tricept pushdowns, arm curls, front shoulder raise, and abdominal crunches. The seat can be set low enough that I (5'10") can get a full stretch doing front lat pull downs.
You can do seated crunches, but the range of motion is limited. The smoothness of operation is acceptable. The machine feels solid but is fairly light. One should consider fastening it to the floor for maximum stablity. When assembling the pulleys, don't overtighten the fasteners or the pulleys will start to drag.Negatives:  The product arrived damaged. The metal ears for one of the pulleys were bent. I considered sending the unit back, but decided to straighten the ears myself - it worked.
Thus less monkeying around between different exercises. I will also make a new a seat for it that is longer. So... this is probably the least expensive lat pull down machine with these features that one can buy, but it does have it's limitations and shortcomings. If you are willing to do a little modification to it to make it fit you - and do what you want it to do -you can save thousands of dollars. That makes it worth it in my opinion to own this machine.
Thus I bought this Valor unit. It came in 2 boxes. Unpacking it and assembling it took about 2 hours. All the parts were there, and the packages of nuts and bolts are clearly labeled. One piece that has metal ears on it to hold a pulley had the ears bent. It was probably crushed during shipping. This worried me because I thought it might affect the rotation of the pulley. Using a piece of wood and a small sledge hammer I was able to straighten the metal ears.
This makes doing behind the neck lat pulldowns impossible. You'll either hit your head on the pad attached to the column in front of you, or bang the bar against the back of your head. There just isn't enough room. It's like this machine was designed for a child or a midget. The seat needs to be longer front to back. When I first tried doing tricept pushdowns I ran out of travel with the cable; it would bang against the upper pulley while pushing down on the bar.
This machine is ok, the lat pull function does its job just like I wanted . The machine doesn't take up to much space .
This is the only single defect that I have found in the design of this machine. However, if it were large enough to do this, it would have probably been too large for my room. Again, I do all of my pull ups in the front so I would never have even noticed this issue had I not read the previous reviewers comments.-My machine arrived with a defective pulley (it was missing an inner bearing part).
The seat is smaller than those found on other machines but again, I fit on it with no problems. I can see someone who is really big having some difficulty but for the average person this is fine. I can see someone as tall as 6' 2" using this with no difficulties. Buy a good low row handle and triceps rope and you're good to go. The metal is strong on this machine and it's relatively light so if you need to move it, it's fairly easy.
The product itself is mostly excellent. Everything works smoothly and is fine for a home gym and should last a long time. When doing the exercises everything feels pretty natural. I also do like the ability to store some weight plates on the lower part of the machine.
