Excellent bench machine, the build quality is solid and durable, providing great stability during workouts. Assembly was quick and easy with clear instructions. It’s multifunctional, allowing smooth and effective leg extension and curls exercises, and it can also used as regular workout bench. Very reliable and comfortable machine to add on to my home gym. Highly recommend!

Solid piece of equipment; easy to assemble; works as advertised. Point of clarification: this equipment does support both 1" and 2" plates, which is not mentioned in the text (although it is mentioned in the videos). I asked Alexa if it supports 2" plates and it said no, likely due to no mention in the text. The photos seemed to indicate that it does support 2" plates, using a sleeve - similar to another bench that I have.

It’s sturdy and works the legs well. No paint issues on my black bench. It’s a little difficult to maneuver oneself for the leg curls. It’s wide where your hips are and it’s at a little bit of a slant. The exercises do work. I’m happy with the quality to price ratio.

This is a decent piece of equipment for the price! Easy to assemble and seems sturdy enough. Has a slight wobble but once weights are on it it’s not really noticeable. The only issue I would note specifically is the seat depth (front to back) is very short - when seated upright it’s small for even me (5’4 female) and my 6’ boyfriend won’t be able to use it upright which forces a lean-back just to do basic leg extensions!

When I opened the package, I’m noticed a lot of scratches and defect on the paint. Many small gouges on the metal. Easy to assemble. Overall it’s ok.

Great piece of equipment. If you have plates, it gets the job done and then some. If you do not have plates, then, obviously you will need to buy some. Highly recommend. 10/10.

The J10 machine is heavy duty and perfect for leg curls and extensions! Unlike most weight benches which have a very limited range of motion when performing leg curls, the J10 allows a FULL RANGE OF MOTION! I also love how the bench tilts up, so that taller people won't hit their feet against the ground when doing leg extensions. There are even multi-level adjustments for leg curls, extensions, and seat tilt! This is the ideal machine for leg curls and extensions!!!
