REP Belt Squat Review – Unexpected Winner w/ VOLTRA I

Last updated on January 25th, 2026 at 07:00 pm

I’ve tried a half dozen ways to belt squat over the years in my gym. An ideal situation would give me a dedicated machine, something like a Rogue Rhino or SquatMax MD perhaps. But the reality is that I am not dedicating a large chunk of my gym real estate to that kind of item. I saw the REP Belt Squat pop up on my local Marketplace for a good price, right in time for my new rack to show up, and it was destiny.

You can get creative and use belt squats for a lot of things. But I mostly just want belt squats. Landmines aren’t great. Most lever solutions are mediocre at best, especially for heavier lifters. DIY solutions and other set-ups are troublesome for a number of reasons. Will the REP Belt Squat be the solution I’ve been looking for? Or will it end up right back on Marketplace? Let’s find out!

Transparency Note

I bought the REP Belt Squat out of pocket, off of Marketplace. I paid $100, so about 30% of the retail price. Keep that in mind as we go. I’ll do my best to paint a fair picture as if I had paid full retail.

REP Belt Squat Overview

The belt squat is essentially a leg press for powerlifters. You get the ability to train the legs with more volume, without having to load a barbell on your back, and approach complete failure without the typical risks that a barbell squat has. I do not have back problems, so I’m not trying to rehab a bad back. But if you have ever loaded a heavy bar and done 10+ reps on squats you know that your legs aren’t exactly the first thing giving up on you.

The Belt Squat takes those pieces out of the equation by loading the weight typically on your hips, which lets you hammer the legs. This SHOULD lead to a bigger squat, because we are not only blasting the legs, but doing so in the same movement pattern as the squat itself. Add to this that we can get creative and use rack arms to change our positioning, or use a belt squat for cable driven split squats, calf raises, or my wife’s favorite… RDLs… and we have some additional niche use cases for this piece.

My main focus is going to be pairing the REP Belt Squat, with our Beyond Power VOLTRA Is. With my new rack, I am going all in on maximizing the VOLTRAs abilities with different attachments and accessories. There is a lot of untapped potential here. The VOLTRAs now have the ability to get set before the weight kicks in. HUGE win for a belt squat set up. I can connect TWO VOLTRAs together, for a total of 400lbs, coming in under the REP Belt Squat max load. I can tinker with eccentric overload and various resistance curves, chains, and bands. And it might just be the solution we need to help my wife squat without knee problems.

REP Belt Squat FAQ

REP Belt Squat Features

The REP Belt Squat is fairly straight forward. Down the middle we have one aluminum pulley that catches the cable and directs it to the second aluminum pulley at the front, which directs the cable straight up from the ground. We NEED a low position for that cable to have any chance at a full range of motion on belt squats.

Off to the sides are 4 holes that help you attach the piece to your rack. It comes with 4 detent pins to hold it into place. 4 pins are needed to make sure we have the least amount of unnecessary movement back and forth, as there is going to be a decent amount of load pulling STRAIGHT UP. I found that I ditched these pins and instead used a set of MAG Pins. They were easier to use, and I have a bunch at this point. The REP Belt Squat holes are 5″ and 5.5″ inches off the ground on center, so you can measure your rack to determine if this will fit or not.

You connect the cable on one end to your cable machine of choice, and the other end to a belt squat belt, harness, cable attachment, or whatever you plan to use. Keep in mind that this is NOT meant for low rows, as the cable comes out of the pulley directed UP into the air, not out and in front. If you tried to do low rows, the cable would fray on the metal.

The aluminum pulleys are a good touch, as they seemed to be smooth in use. I never had any hiccups or feelings like this was catching. I replaced the included carabiner with one of my favorite carabiners and added a rotating shackle to the end that connects to my VOLTRAs.

REP Belt Squat Performance

I needed this combo to check all of the boxes for my belt squat use. Easy set up without eating up tons of space, a good starting position, full range of motion, and plenty of room to progress without loading every 45lb plate in the gym. Let’s see how it did.

Set-up & Space

The REP Belt Squat weighs 41lbs. Far from a SMALL rack attachment, but significantly smaller than a dedicated belt squat machine. It manages to fit on my mass storage rack, then be carried over to the power rack for set-up. But we have no handles at all, which makes it difficult to move and get into place without fear of dropping on your rack or foot.

We have a cable that is just free floating in space, which means it is going to bang your foot, leg, rack, floor, you name it.

The last consideration here, is that the REP Belt Squat cable length is static at about 100in in total length, or 75in from the top of the back pulley. Meaning that if you don’t have a rack that perfectly fits the dimensions in terms of height, you are going to need to go custom for the cable length.

Mine happened to work pretty perfectly with my very tall rack… but the downside here is that it makes set-up a little less than ideal. I need a ladder to move everything around every time even though I am 6ft tall. This is definitely right on the verge of being too much set-up currently, but I am using this enough that I am highly considering getting dedicated mounts for the top cross-member.

Starting Position

The starting position is an issue I have had with almost every belt squat I’ve ever used. Even the kickstand for the Gentleman fitness Belt Squat wasn’t tall enough for me, so it only KIND of worked.

REP addresses this in their design for their own rack system by using a chain and hook. You can loop the chain and hook over a barbell, from a strap connected to a pull-up bar, or whatever stationary piece you can connect it to.

Luckily for VOLTRA users, we have the Auto Load and Auto Deload features. This means that we can TURN OFF the resistance on the VOLTRA at the beginning of our set… get hooked into our belt, wait a few seconds in place, and then the resistance will kick in. We can do our set, stand still for a few seconds, and the VOLTRA will turn off the resistance, letting us unclip and put the carabiner back down to the floor.

So we can put whatever weight we want on here, without having to stand up awkwardly, hook anything to a catch, or any other funny business.

The only issue here is that you need to be able to reach the VOLTRA or use the app, to make this feature work, if you are operating TWO VOLTRAs you have to do it twice, and the weight doesn’t fully kick in until the second rep. So, our starting position problem is solved with one of the VOLTRAs coolest features.

Full Range of Motion

Full range of motion is a tricky one. The Rogue Rhino solves this by having the pulley be INSIDE the platform itself. I’ve seen several people make platforms for their REP Belt Squat Attachment, which is a decent option. I don’t exactly like standing on surfaces for belt squats that aren’t locked in though. It is a reason why I’m not a huge fan of leveraging T-Bar Row Platforms for Belt Squats. One small shift of weight and the entire thing can go sideways.

Instead, I think you have to primarily focus on choosing the right belt.

The included belt from REP is… ok. It is a lot like the one that came with the Gentleman Fitness Belt Squat. I owned the original Spud Inc Belt Squat for a long time which was comfortable but didn’t have any adjustments. So if it was too long… too bad. I was using the Freak Athlete Hyper Pro Belt Squat Belt for awhile. It is better as it has a lot of adjustment points, but the metal D-Rings were constantly digging into my leg.

After a couple weeks straight of metal scratching my inner thighs, I snagged the Spud Inc Pillow Belt Squat Belt way back in 2022.

The belt is super soft, it has 7 adjustment rings, and the entire belt is cloth, meaning that any dragging or rubbing doesn’t create any issues.

My wife is able to use this belt at 5ft6 and about 150lbs, and I’m able to use it at 6ft and 250lbs, without any issues AND we are able to get full range of motion here.

The one thing that could be better though…

The REP Belt Squat has a decent amount of play to it. It makes sense, as it likely needs this to be compatible with multiple racks… but you can see how the front pulley lifts off the ground quite a bit. If this didn’t happen, I’d probably get a loop or two back on my belt.

Progression

The last piece is around weight and progressions. As I mentioned, I’m not looking to have to grab 14 x 45s every time I’m going to hit Belt Squats. The good news with the VOLTRA combo here, is that I haven’t managed to max out the resistance yet. Now I am using TWO Voltras, because my working sets have me at just over 200lbs of resistance for my 10 to 15 rep range…

But remember that I hit a 550lb squat just a couple months ago, can handle 4+ plates on leg extensions, and that other Belt Squat had me running with 630lbs of plates for the same rep range. I double checked the resistance on the REP Belt Squat by the way and it is a true 1:1 ratio.

So the fact that I am pushing some hard sets with just a little over 200lbs of resistance on the VOLTRAs means that I personally have a LOT of room to advance, and most people are going to be perfectly fine with just one VOLTRA.

Additional Notes

You probably want some kind of balance support here. We’ve been using our Spotter Arms which work perfectly well. Just a little something to make sure we aren’t tumbling over.

You can definitely perform other exercises here if you want to, the two we’ve been doing are Belt Squats and RDLs… My wife is actually doing a superset of the two and absolutely hating walking the next day. I think with how easy the VOLTRA is to adjust on your rack, other exercises like calf raises and curls and stuff probably aren’t worth rigging up.

Should You Buy The REP Belt Squat?

Long time readers probably remember that my wife has a troublesome knee. It historically has not liked squats and we have tried a LOT of options. This combo of the REP Belt Squat, VOLTRA I, and Spud Inc Pillow Belt however, has worked and we’ve got squats added back into her program consistently for the first time in probably 5 years. That alone is worth this combo for me, but the fact that I’ve been consistently using it as well pushes it over the top.

REP did tell me that they eventually plan to make a V2 of the Belt Squat, but it isn’t in the works currently so I wouldn’t be holding out for the V2 any time soon.

I’ve done a lot of belt squat variations over the years, and nothing has stayed in the rotation very long. I have insights into products coming to market from a few different companies that MIGHT compete with this set up. But for now, this is the BEST Belt Squat we’ve used in our gym. And it looks like it is going to be a mainstay for quite some time.

Other Options On The Market

BulletProof Fitness has their Cloud 9 belt which has gotten some great feedback. And REP told me they have a new belt squat belt coming very soon that looks pretty robust.

One thing I’m not sure about is that they both use metal D-Rings. My concern would be that those would still dig into my legs, leaving me going back to the Spud Inc.

Wrap Up

I think this kind of solution is going to become more and more available in the near future. With more rack integrated cable systems, with more units like the VOLTRA I, we are going to see more people get away from the large belt squats like the Rhino, and more companies adopt drop in options that are affordable, moveable, and kick some butt.

For now, the REP Belt Squat is our go to solution.
