FREQUENTLY ASKED QUESTIONS

Can the Y3 be used on its own, or does it require the O1 bench?

The Y3 can be used as a standalone leg attachment, and it can also pair with the O1 adjustable bench for a wider range of lower-body exercises in one setup.

What exercises can I do with this setup?

The Y3 supports leg extensions, leg curls, Nordic curl variations, and split-squat style movements. When paired with the O1 bench, it gives you more positioning options and a more complete lower-body training setup.

Does it fit Olympic plates or only standard plates?

It supports both 1" standard plates and 2" Olympic plates, giving home gym users more flexibility with the plates they already own.

Is the adjustment range enough for different users?

Yes. The Y3 includes 6 height adjustments, 7 rear-leg settings, and 4 front-leg settings, making it easier to fit different user heights, exercise setups, and training positions.

Is it stable enough for home use?

The Y3 uses a reinforced steel frame and a compact freestanding structure designed for home and garage gym use. When properly set up, it provides a more stable platform for focused lower-body training than improvised bench attachments.

Does it take up a lot of space?

No. One of the main advantages of the Y3 is its compact 56 x 75 x 81 cm footprint, which makes it easier to fit into a garage gym or home workout space than larger dedicated leg machines.

Is this a good option for beginners, or is it mainly for experienced users?

It works well for both. Beginners can use it as a compact way to train legs at home, while more experienced users will appreciate the adjustable setup, plate compatibility, and ability to combine it with the O1 bench for more exercise variety.

Customer photo review of Y3 Leg Extension and Curl Attachment

I was very impressed with how easy this was to assemble. It works great with any brand of bench. This slides underneath your bench and you can adjust the height for both leg extension and leg curl which is wonderful. I am 5'1 and can use this just as easily as my husband who is 5'11. This is absolutely worth every penny if you have a home gym!
