What's the weight capacity of the Squat Harness V4, and is it safe to use with free weights like a barbell or hex bar?

The Squat Harness V4 has an estimated load capacity of 950 lbs, but it's worth knowing that free weights put more direct force on the straps compared to cable machines or resistance bands. If you're pushing past 500 lbs with a barbell or hex bar, we recommend testing each lift carefully and working your way up slowly. The hex bar is actually a great option because it allows for both squats and deadlifts, giving you more versatility while keeping things more controlled.

I'm new to harness squats — is the Squat Harness V4 beginner-friendly, and how do I get started safely?

Absolutely, it's designed with beginners in mind too. If you're using a functional trainer, start by pulling a low bench close to the machine so you can hook in while seated, then use the sides of the machine for support as you stand up. It's strongly recommended to hold the machine for balance during your first few sessions rather than going hands-free right away. The included band hook straps and instructional videos make the learning curve much more manageable, and if you're recovering from an injury, taking it slow with machine resistance first is the safest approach.

How does the V4 improve on the previous version, and who is it best suited for?

The V4 was built with both durability and comfort in mind. The main straps are now 3 inches wide (up from 2 inches), rib padding has been added around the bottom of the harness, and the chest buckle system has been simplified so there's no confusion about what adjusts where. The chest straps are also longer to accommodate larger body types. Whether you're a serious powerlifter, someone rehabbing a knee or back injury, or just looking to load up your leg day without putting a barbell on your spine, the V4 is a versatile fit.

What equipment can I use the Squat Harness V4 with?

The V4 is compatible with a pretty wide range of setups — functional trainers, resistance band platforms, barbells, and hex bars. The included band hook straps connect to the fabric loops on the sides of the harness, and the D-rings at the top and bottom open up additional options like reverse-band squats. For barbell or hex bar use, you'll need Loading Straps or Barbell Hook Straps, which are sold separately. There are demo videos available for each setup to walk you through the process step by step.

How do I care for the Squat Harness V4 to make sure it lasts?

Since this harness is built from heavy-duty webbing and sees a lot of sweat during intense training, regular cleaning goes a long way. Cold water hand washing with a light detergent and hang drying is the recommended routine. Skipping this can cause salt buildup from sweat to calcify in the buckles over time, which affects their function. The harness also comes with a 90-day manufacturer warranty, and if you ever run into issues, you can reach out directly to Jason at support@squatharness.com.

Should be able to edit your purchase and delivery information on the site.

Good customer response when I mentioned that I submitted the wrong address for delivery, however, after I was told my address was corrected, it did not change on the site and it went to the incorrect address.
You should be able to edit your purchase and delivery information on your site.

UPDATE November 30, 2025. We have implemented an easy way for customers to edit their address for up to two hours after an order is placed. This can be done from the post purchase email you receive, the Order Confirmation page or when you login to your Order History: https://account.living.fit/orders

ORIGINAL REPLY
Thank you for taking the time to share your feedback. We really appreciate it, and I want to clarify what happened with your address change so you know exactly where things went wrong.

When you reached out, our team let you know that we would do our best to update the address. Because this item ships directly from one of our third-party partners, we are not able to edit the order ourselves once it enters their system. In this case, the vendor shipped the package very quickly, which meant the address could not be updated in time even though we tried to intervene before it went out.

We understand how frustrating this is, and we are reviewing how we communicate these situations so expectations are clearer moving forward. We are also exploring better ways to allow address updates when possible, although this can vary based on the vendor.

If there is anything else we can do to help with this order, please let us know. We want to make it right.

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.
