  • 3-inch main straps for maximum durability: Wider than V3 — distributes load more evenly across the torso and resists wear under heavy, high-frequency training better than narrower strap designs.
  • Rib-area padding: Under heavy loads, the harness tightens against your torso and without padding the straps create significant pressure on the lower ribs. The padding distributes load more evenly for training at high intensities and high volume.
  • Estimated 950 lb load capacity: Engineered for heavy cable machine training, free weight loading, and resistance band work across the full range of Squat Harness exercises.
  • Chest-only buckle placement: Simplified from V3's two-buckle layout — faster to put on and take off, fewer adjustment points to manage between sets.
  • Top and bottom D-rings: Multiple attachment points for cables, loading straps, band hook straps, and other Squat Harness accessories — versatile setup for the full exercise library.

The Squat Harness V4 is a 6 lb heavy-duty harness with 3-inch main straps, rib-area padding, chest-only buckle placement, top and bottom D-rings, and an estimated 950 lb load capacity. Includes band hook straps.

• Weight: 6 lb
• Main straps: 3-inch width
• Load capacity: 950 lb estimated
• Padding: rib-area padding
• Buckle placement: chest-only (simplified from V3)
• D-rings: top and bottom positions
• Included accessories: band hook straps
• Compatible with: cable machines, resistance bands, barbells, trap bars, free weights

Q: What's the main improvement over the V3 in the V4?
A: The V4 upgrades to 3-inch main straps (wider and more durable than V3), simplified the buckle placement to chest-only for easier setup, and increased the estimated load capacity to 950 lb. Extended chest straps were also added to accommodate larger body types.

Q: How do I attach a barbell or free weights to the V4?
A: Use the included band hook straps for tube-style resistance bands, or attach Loading Straps (sold separately) to the D-rings to connect barbells, trap bars, or kettlebells.

Q: Does the rib-area padding make a noticeable difference?
A: Yes — under heavy loads, the harness tightens against your torso and without padding the straps create significant pressure on the lower ribs. The padding distributes this load more evenly for training at high intensities.

Q: Is this safe to use without a spotter?
A: For cable machine training, yes — releasing the cable stack is straightforward. For free weight loading (barbells), Squat Harness recommends having a spotter to assist with unloading after each set.

I was very pleased with the whole purchasing process.

Purchasing the Bands through the website we smooth, communication from the company as to the status of my order was timely (I very much appreciated it:) and the Bands arrived in the expected time frame.

Customers praised this harness for its military-grade build quality, comfortable padding, and versatile design. Many reported it relieved shoulder and back pain while allowing heavy squats with bands, cables, and functional trainers. "Feels like I'm about to fly a jet," one noted. Some found the price high but justified by durability.

Injured tendon which made it near impossible to squat with a barbell due to the bar press against

Injured tendon which made it near impossible to squat with a barbell due to the bar press against my shoulder. Tired belt squats but alot of unnatural tension on my hips and knees. This harness hooked up to my functional trainer is awesome. Also got the metal wedge and both combined is a spot specific arsenal on your legs and calves. Highly recommend

Solid, comfortable and built for serious loading

Just received the Squat Harness V4 and first impressions are very good. The build quality feels solid right out of the box, strong stitching, durable materials and a comfortable amount of padding. It sits securely once tightened and doesn’t feel awkward to set up.

I’ve only done a few initial sessions so far, but it already feels stable and well balanced under tension. The load distribution seems much more comfortable than expected, especially when working with bands or higher resistance. You can tell it’s designed with real training in mind.

Looking forward to putting more sessions on it, but so far it feels like a well-built piece of equipment that should hold up well over time. If you’re training with bands or looking for a way to load squats heavily while keeping your back happy, this harness does exactly what it’s supposed to do. Highly recommended.

Incredibly well designed. Very high-quality.
Worth the price premium.

however, as a woman with large breast implants,
I do wish the second set of horizontal straps at the front would connect at a point that was lower.

Very much needed for home gym! Quality is amazing lol it feels like i'm about to lock in and fly a jet. It's very well supported and secure.This is perfect for the combo with bandswork for legs without the lower back pain, I work 12 hours shifts as a nurse in a high intensity environment, constantly on my feet. This saves the added back pressure!

Much more heavy duty than I thought, the quality you can feel when it's in your hands makes the price much more understandable.

Works great for spilt squats and good mornings

Nice addition to leg day.

I used the harness with my belt squat attachment and instantly noticed more feeling in my glutes and quads. Still figuring out how to best use it with my functional trainer. I’m sure I’ll find many more ways to use it.

Excellent design, super functional

The possibilities are endless with this harness. It is extremely well made and very comfortable. Bands, functional trainers, single cable pully towers, hex bars, I could go on and on. This harness takes training to the next level and opens world of training variations. Every gym, home or commercial, needs one of these.

Good for bad knees

I have a home gym that my friends and I use. Several have bad knees and therefore avoid squats. I bought this to see if it would allow them to get squats back in their game and it has! Everyone is now squatting and getting stronger!

This is such a worthwhile upgrade from the V3. Definitely worth it!

Awesome Product!!!

After watching several reviews online and on YouTube I decided that I had to purchase this Harness. I said I have the perfect rack at home for this.
Upon receiving this, I immediately put it to work. Took a few minutes after making very minor adjustments. LOL! This thing is freakin super comfortable.
After working out with it for about 10 minutes I took it off and said to myself, I wish to hell I would have thought of this.
Long story short, it’s really worth the money. It truly is!!! I’m glad I added this piece of equipment to my arsenal.

Fantastic Quality and Design

The Squat Harness V4 is a great piece of gym equipment. I can really work my quads hard without stressing the lower back with the Squat Harness. Pairs really nicely with the footplate. The customer service is also outstanding! Couldn't be happier with my purchase!

Enter the V4 Harness

I had left a review if my V4 early on and I will admit , I was too critical too fast. I likes the harness upfront but found the accessory straps to be unusual and difficult to size and strap on properly for using my Rep open trap bar. It's funny that I only bought this harness for my trap bar since my arms are now giving me problems and trying to maintain my exercise level. After I had purchased an extra strap accessory that has the metal cup handles, that solved my issue immediately, and I was off to the races.
I have a force USA Smith machine. So I started
To use this harness with one pulley, connecting it right in the center of my harness to do the squats, but it was unusual, just because my machine in particular is different than most. At first I thought I would need a stepper block to give me a little more height so I could get a deeper squat. , the included accessory straps just would not work out, so I decided to go with the chains that came with my dip belt. Using a couple medium sized carabiners, i was able to stand in the middle of my smith machine and connect either side of the pulleys to my vest. The bonus here is that I am able to use the smith bar as a handle to maintain balance. Learning to do this, I was able to fine-tune the exercise and can now squat very safely.
All the weight I desire. Testing the limits from lightweight carefully and slowly. Till I reach my heavyweight goals. The strap is extremely comfortable even when maxing out. Does not leave any marks on my back or shoulders? Like my hack, squat and leg press combo machine always did. I also discovered that I could use this vest on the smith bar to do calve raises with a calve block , using the same accessory straps that I use for my open trap bar. This is so much easier than holding dumbbells, and doing the same exercise as i'm able to far exceed the amount of dumbbell weight I could hold. I used to use wrist straps, but the heavier. The way it got, the harder it was on my shoulder's down to my hands. The vest helps me isolate the exercise to my calves and feels so much easier on the rest of my body.
The timing I purchased the belt. Was perfect since I had discovered. I have tissue degeneration in my hips, and doing exercises on the hack. Squat and leg press had made it impossible to continue. Doing heavy weight in those positions. I crossed over to the squat, harness pretty much out of an act of fear that I would never be able to do hard.Leg workouts again. All other leg exercises don't affect my hips, just the big ones, like the hack. Squat and leg press where i'm able to keep size on my legs. It's after two months of using the squat harness after a week, a physical therapy to figure out a new leg routine, i have not lost any form or muscle mass on my legs, which is amazing at the same time. The pain in my hips have subsized. At this point I can say, I am sure there are Other exercises, I have not yet tried or discovered using this product. I absolutely love this amazing
Gym attachment, and I now consider it one of the main staples in my garage gym.

Amazing product

I was a little skeptical at first glance of this product, but after going through enough belt squat belts that were uncomfortable I phase this a shot. This has now become my go to for squatting with my functional trainer and I can now do weighted squats anywhere by pairing this with resistance bands. Every day I am figuring a different way to utilize all the different D Rings and straps for creative and fun workouts. This piece is as versatile as your imagination will take it.

By far the best option for cable based squats/leg work.

Have tried a number of belt options squats for squats, and this is by far the best. I can also squat to full depth on the voltra w/ travel board.

Great well built all purpose harness

I bought the V4 harness after watching The Kurt Locker review of the V3. The hardware is top of the line in my opinion. The harness reminds me of some of the harnesses that I've come across during my time in the military.

This harness is great for pulling sleds, squating, and a few other exercises.

Derrick
Heavy duty, kinda pricey

I definitely feel confident about the safety and durability of this harness. I was a little hesitant at first because of the price, but after carefully comparing the features to the older version, I knew this would be the better choice. Definitely the best option for squatting with resistance bands as Im not a fan of holding those bars.

Best leg accessory

I was eyeing the squat harness v3 for a while, but when I saw this with its wider straps and extra features, i knew it was going to be perfect. And it did not disappoint! It was simple to put on and figure out. Feels really heavy and supportive. I feel confident to go as heavy as my legs will allow. I know I won't exceed this thing's limits in this lifetime, and that's a reassuring feeling.

T
Tim
Better than imagined

I was on the fence between getting this or the V3. All i can say is this was worth every extra penny! The width/ thickness plus the extra padding in all the right places makes this the perfect piece of lower body equipment. If you're a belt-squat machine user like myself, I highly recommend the Squat Harness V4. No more hipbone pressure from old fashioned squat belts

N
Nate
Finally I can squat again

I have a shoulder injury that makes barbell squats really painful. This squat vest allows me to squat again without any pain in my shoulders. Im grateful just to feel my legs fatigued again even if it's not as heavy as I once squatted. I just make up for it with higher reps.

J
James
Best harness yet

I have the original and the V3. Nothing even compares to this one. The width, comfort, and functionality is unbeatable, and I feel 100% safe knowing that these straps will not break on me in this lifetime. I find new ways to improve my leg workout every time I use this.
