Guidelines of use

Set the hook straps by attaching the carabiners to the fabric loops hanging on the sides of the harness. It is not recommended to attach them directly to the bottom D-rings (those are for tube-style resistance bands only). Alternatively, you can use the daisy-chain method to increase the range of motion, which I explain below.

Pull up a low-seated bench close to the machine so that you can place the hooks on the bottom pulleys while seated.  Once you are connected to the desired weight, use the sides of the machine to help pull yourself up into the top position.  At this point, you can either squat while holding the machine for support or you can grab the support loops located above your shoulders.  It is recommended to start by holding the machine until you feel confident about the setup and movement, especially if you are still recovering from an injury*.  

In between sets, you can use the bench to rest or to unhook yourself from the pulleys when finished. 

You may need to daisy chain your hook straps if the shortest setting doesn’t give you enough range of motion.  (For instructions on how to daisy-chain your hook straps, please refer to the video.   This is also useful if you plan to connect to a barbell or hex bar with the Loading Straps.) Alternatively, you can purchase the 8-inch hook straps for increased ROM.

Use a bench in a similar fashion to the instructions above for functional trainer use, except keep it behind your resistance band platform.  Set the resistance band hook straps to the fabric loops of your harness and have the desired band set under your platform.  Carefully connect each hook to the corresponding ends of the resistance band while keeping both feet on the platform.  Once connected, grab your shoulder straps or use suspension straps if desired to help you get started.  It’s important that both feet remain on the platform while connecting or removing the band from the hook straps.  This is why having a bench behind you is advised because it allows you to rest between sets while keeping your feet on the platform. When finished, simply unhook each side from the resistance band. Please note that it’s important to test the length settings of your straps to see how much tension you get at the top position.  Too much tension can increase your risk of injury*.

Please be advised that using The Squat Harness V4 with free weight puts more direct force on the straps compared to cable or resistance band use, and therefore it is advisable to test each lift carefully once you exceed 500lbs.  While we continue to test each batch and maintain that The Squat Harness V4 can handle free weight loads up to 950lbs, free weights are less stable than machine or band resistance and come with increased risks of injury if not used with care*.

You have the option of using Loading Straps or Barbell hook straps (both sold separately).

 If using the barbell hook straps, it is advised to keep your hands under the hooks throughout the lift.  Connect the carabiner of the barbell hook straps directly to the front/ sides of the harness where the original hook straps usually connect, but wrap the carabiner all the way around the straps (video available for reference).

How-to Video >

If using the Loading Straps, use the original hook straps that come with the harness via the daisy-chain method (video available) in order to create the right range of motion. To connect, wrap each loading strap around the knurled portion of the bar where you plan on connecting each hook from the harness.

With a regular barbell, you can mainly do classic deadlifts, whereas the hex bar will allow you to do squats or deadlifts, depending on how you have them set up.  With hex bar squats, you also have the option of holding suspension straps or another secure structure for support.

It is also recommended to slide the bottom cushion straps all the way in so that they are behind the connector straps (video reference above).  This will minimize discomfort or pressure during your lift. 

Important Safety Notice

Use at your own discretion. The Squat Harness V4 is designed for experienced users familiar with proper exercise technique. Always ensure proper setup, adequate warm-up, and appropriate weight selection. Consult with a qualified fitness professional if you're unsure about exercise execution. Beyond Power is not responsible for injuries resulting from improper use or failure to follow safety guidelines.

Care instructions

We recommend cold water handwashing your harness frequently with light detergent and allowing to hang dry.  This supports its longevity as calcified salt from sweat can build up into the buckles overtime.
