Hydra Leg Extension
Great product so far. Super happy with it.
Would be 5 stars but it’s challenging to store it with how the pins insert.

Leg Curl / Leg Extension Rack Attachment
I’m seriously impressed! This is exactly what I was looking for. The quality and build are top-notch—super solid and sturdy. It’s also incredibly easy to set up and take down when you're done. If you’re tight on room, this is a total game-changer.

Nice add-on
Very nice add-on for my cable tower and a great trade off for not having a dedicated machine but it can be a bit awkward putting it on/taking it off.
I'm hoping it gets a bit more easy to use/keep set up when I replace my current rack with a BoS squat rack :)
