Awesome for extensions, okay for hamstring curls
Had some issues with a few minor pieces missing (washers and an end cap) and a piece that needs to be replaced; however, the seller responded immediately to my message and is already correcting the issues.Awesome machine for leg extensions…super smooth. Still trying to get used to the leg curl use…it’s a little difficult to get off the machine because of the extension handles.

Reviewed in the United States on May 5, 2024
The leg extension and prone leg curl machines are a few of my favorites at any gym. I am sure a lot of us feel the same way. These are a great way to hit our leg muscles separately from doing traditional exercises like squats or deadlifts. After reading reviews, I was confident in purchasing this machine. The leg extension feels great, I don't like the way the handles are set up, I have to lean back a bit and I find myself holding the pad itself and not the handles. You CAN set it up to have the handle facing the opposite way so I might prefer it better that way but it is not a huge deal to me.

The prone leg curl feels great. With only 10's on each side, it felt challenging. Unlike cable machines commonly found in the gym, since the machine is plate loaded there is a different force curve. It is harder during the first half of the movement, but this is also good because you can and should control the movement as the weight passes back through the axis point (the middle or sticking point, during the eccentric phase, "on the way down").

With "not great" knees and ankles, I would sometimes take trips to the gym to just do these exercises and now I don't have to as I have this machine at home. I really like this machine and it was worth the purchase.

Reviewed in the United States on January 21, 2024
Now that I had a few days to use this leg extension/curl machine, I’m giving my opinion to help my fellow shoppers.

This machine is very heavy and built with thick structs. It very sturdy and does not flex at all. The pads are thick and should last a long time.

I have 3 negatives. First is that there was only one flange bushing in the box. This is essentially the bearing that the only moving part pivots on. There should be 2 in my opinion. My machine arrived on a Friday of a 3 day weekend and I didn’t want to wait several days, so I purchased another bushing and was able to complete my assembly. With the second flange bushing installed, the bolt is now a bit short to fully engage the self locking nut. I’m not sure if this unit is designed to use 2 bushings. I suppose I could have waited and call back after the long weekend, so no stars taken off for this. (The flange bushing is available: Hillman 58102 Flange Bearing, Bronze 1/2 X 3/4 X 1 X 1/2-Inch, 4-Pack)

Second is the machine is unnecessarily high at the business end. The highest point near the pivot point is 28.5 inches! This maybe ok, but the front is only 20 inches tall. The 8.5 inch drop makes it tricky to get up from doing hamstring exercise. I removed the handles at the middle to make it easier to unmount. If you have mobility issues, then this could cause difficulty getting in and out. Subtract 1 star.

The last point and I think the most important is that for me (6 ft, 180 lb) it’s impossible to properly line up the center of rotation for my knees with the center of the pivot point while doing extension or curl. This misalignment will put a bit of extra stress on the knee joints if I push hard with heavy weights, so start easy and pay attention. I wish the pivot point was extended out another 2 inches, or make the sitting surface adjustable. Subtracting another star.

Given the 3 negatives, I would still recommend this machine because given the price it’s so well built and is functional.

(Update after 1 month of use).
I’m adding 1 star for high quality of the build; the movement is very smooth especially with 2 flange bushings at the pivot.

It’s durable and easy to assemble and does exactly what I expected it to do. I bought it for our CrossFit gym that has about 200 members. I chose this machine because all we needed was the leg extension and leg curl. The other machines that are more versatile didn’t appear fit the “commercial” grade I was Loki g for and this machine fits that need perfectly. If you use this for home and need more versatility go with the other ones. But if you want durability and stability and just need these two movements this is the one!

 Everything about this machine is perfect and heavy duty. Only thing is one of the leg pads slide back and forth after being locked with adjustment knob while the other pads for hamstring curl stay locked and don’t slide side to side. You can easily see in my video what I’m referring to. I worked out with it like that and didn’t really have an issue was just curious if it’s supposed to be like that so I asked deltech and so far that have suggested switching the rods so we will see

I'm really impressed by its durability and sturdiness along with its functionality. The gauge of steel is thicker than expected. Range of motion is great along with the tension throughout the movements. I even put some resistance bands on it for a more machine feel but it works great without them too. It's also great for different heights. I'm 6' tall and my wife is 5'3". It easily adjusts and works for both of us with more room for adjustment for even taller or shorter people. If you need something inexpensive to isolate quads and hamstrings, this is it.
