AnicZon Leg Extension/Leg Curl Machine Review: Is It Worth It?

I already owned a leg extension and leg curl machine. Then AnicZon sent me theirs to review, and within about two weeks I got rid of the one I had. That’s not a line I write often, so let me explain exactly what made me swap, what I’d change about this machine, and whether it belongs in your home gym.

The Short Version

This is a plate-loaded leg extension and leg curl machine with a 330 lb user weight capacity, four separate adjustment points, and the ability to run leg extensions, lying-style leg curls, and reverse curls off the same frame. It replaced a machine I already owned and liked well enough. The two knocks are a positioning pin that sits right where your leg wants to go and a backrest that could stand to be a couple of inches wider. Neither one sent it back to the garage.

Build, Padding, and Weight Capacity

Some context on why I judge equipment the way I do: I’m 270 pounds. Seat width, padding density, and whether a frame flexes under me are not abstract spec-sheet items — they’re the difference between a machine I use and a machine that becomes a very expensive coat rack. I’m also a NASM Certified Personal Trainer, so I’m looking at whether a piece of gear lets someone actually get into the right position, not just whether it moves.

The rated user weight capacity is 330 lbs. The seat is wide, the padding is on the firmer side rather than the squishy foam that bottoms out after six months, and the frame doesn’t wobble or creak when I’m driving through a heavy set of extensions. That last part matters more than people realize. A machine that shifts under you makes you brace instead of contract, and you leave reps on the table.

The handles are solid and positioned where you’d want them. On leg extensions you’re pulling down into the seat to keep your hips locked, and on curls you’re using the back handles to hold position. Both grips do their job without you having to reach or contort.

Adjustability: Where This Thing Wins

This is the reason I got rid of my old machine. You get four meaningful adjustments: the leg pads, the ankle pad position, the seat travel, and the back angle. That’s a lot of range for a home gym machine at this price point.

Why does that matter so much? Because the knee is a hinge and a leg extension machine only works properly when the axis of the machine lines up with the axis of your knee. If your seat is too far forward, your knee sits ahead of the pivot and you’re grinding the joint instead of loading the quad. If the ankle pad sits too high on your shin, you get a pressure point that makes you cut the set short before your quads are anywhere near done.

Form cue on extensions: get the seat set so the back of your knee is right at the edge of the pad and the pivot lines up with the side of your knee. Ankle pad just above the joint, not on it. Then drive to full extension, pause for a beat at the top, and control the way down. The eccentric is where most of the growth is on this movement, and it’s the part everybody rushes.

On the back angle — a more reclined position lets you get more hip extension, which changes how the rectus femoris contributes. Set it more upright if you want to bias the vastus muscles. Being able to pick is a real advantage, not a spec-sheet bullet.

Switching Between Extensions, Curls, and Reverse Curls

The changeover from extensions to curls is quick — you’re repositioning the pads and your body, not disassembling anything. Once you’ve done it twice you’ll do it in under a minute between sets.

For curls you get into position and use the back handles to anchor yourself. This is important: if you don’t hold yourself down, your hips lift on every rep and the hamstrings stop doing the work. Grab the handles, keep your hips pinned, and curl. Same rule as extensions — control the way back.

The machine will also do reverse curls, which gives you another angle on the hamstrings. Between the three movements you can build a genuinely complete leg accessory day around this one frame, which is the whole argument for a combo machine in a home gym where floor space is finite.

Programming note: leg extensions and curls are accessory work, not your main lift. Put them after squats, hinges, or leg press. Two to four sets in the 10 to 15 rep range with a real pause at peak contraction will do more for you than loading it up and swinging half reps.

Two Things I’d Change

The pin. There’s a positioning pin that sits in a spot where it gets in the way. It’s not a safety problem and it doesn’t stop the machine from working, but it’s the kind of thing you notice on every single session, and once you notice it you can’t unnotice it. A relocated or lower-profile pin would fix it entirely.

The backrest width. At my size, a wider backrest would be more comfortable. If you’re a smaller person this may never register for you. If you’re a bigger lifter, know going in that the pad is adequate rather than generous.

I’m listing both because you should hear them before you buy, not because either one is a dealbreaker. I kept this machine and got rid of the other one knowing about both.

Olympic Plates Only, Plus Plate Storage

This is the spec that will decide the purchase for some of you: the loading sleeve takes Olympic 2-inch plates only. If your home gym is built around 1-inch standard plates, this machine does not work for you without adapters. Check your plates before you order — this is the single most common way people get burned buying plate-loaded equipment online.

On the plus side, there’s plate storage built into the frame. Small thing, but in a garage gym every plate that lives on the machine instead of on the floor is a plate you’re not tripping over.

Assembly

Assembly was reasonable and — this is the part I actually want to credit — the parts were labeled. If you’ve ever built a piece of home gym equipment out of a box of forty unmarked bolts in six similar lengths, you know how much difference labeling makes. Set aside an afternoon, work on a flat surface, and leave the bolts finger-tight until everything is aligned, then go back and torque it down.

Who Should Buy This One

Buy it if you already have Olympic plates, you want leg extensions and leg curls without giving up the floor space for two separate machines, and you value adjustability over a longer spec list. Buy it especially if you’re a bigger lifter who’s been let down by flimsy leg machines — the frame holds up.

Skip it if your gym runs on 1-inch standard plates, if you need a selectorized weight stack for fast drop sets, or if you’re a larger person who wants a wide, plush backrest above everything else.

The real endorsement here isn’t a score out of ten. I owned a competing machine, this one showed up, and the other one left. That’s the review.
