Question: Does it allow you to do Tricep extensions? Top pulley must not covered,  Extensions are done with back to machine, leaning away
Document: Only about a 10 minute mistake but an easily done mistake. I lubed each pulley and the slider mechanism with wd-40. Not sure if that helped but it sure didnt hurt.Have had no problems so far with the machine functionality or parts. It also is quite sturdy even with its smaller footprint. I have done pulldowns and rows with 180lbs. on the machine and it doesnt sway or feel like it will tip.
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.
For sitting rows you have to adjust the chain aswell. But often whin between sets the cable comes off the pulley and you have to move it back into place by hand. I'll think of something to keep it in place cause it can be annoying. And lastly, the ab setup is junk. But having the cable there can come in handy for other workout.Overall, for the money it the Cb-12 works.
I purchased this product after weeks of searching for something that would allow me to continue the lat pull-down exercises that I was doing in physical therapy once I was discharged and continuing to recover on my own.
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).
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.
Let me start off by saying I took a chance based on what the other reviews said. Let me explain. I am 6'2&#34;. This machine would be better for me if it was, say, 4-6 inches taller. It really is quite compact.Construction is good. Pulley action is good. Directions leave a little to be desired. The least they could do is offer a tip or two on the cable installation schematic.
I am 5'7" and the machine is perfect for me. However, I can see really huge guys having an issue with the size. I believe one of the previous reviewers commented on this fact, sating that he thought the machine was made for "midgets" or something like that. While I don't agree with that, I am not 6'4" and 280 pounds either...-If you want to do pull downs behind the back (I never do), this is not the machine for you.
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.
Make sure you feed the B cable from the kick plate back toward the back of the machine. Any other way will require you to backtrack. Quality of the machine is very good. Feel is good. Lubricated it with some WD 40 and it is very smooth. Tried to call Valor Athletics to give them my feedback and only got a voice recording. Left my name and number. They never called back. The next day I could never get through.
