TNT Hellbox Belt Squat Attachment

Because of chronic lower back issues, I haven’t been able to barbell squat. Belt squats have kept me in the game but I hadn’t found a great home gym set up till I got the TNT Hellbox. I have no complaints, I do wish fringe or someone would make a better kickstand but that’s a different subject. I use axle collars to secure the weight horns. I use the Hellbox every leg day, 2x a week. Even with 2 voltras, I prefer the feel of the TNT Hellbox. I also use it for calves! Thank you Porter for such an excellent upgrade! Worth every penny.

This 'makes' the mammoth for me. There are things that I think could be refined to justify the price (below), but the functionality and 'quality of use' improvement is bar-none. The handle / adjustments allow you to make huge adjustments to the belt squat / stimulus and even use it very well for calf raises, deadlifts, modified viking presses, and other push/pulls with the handles. Plus, this is turning into an eco system with the option for additional attachments into the hellbox. Now some improvements - angle up the weight arms like Fringe's dual horns; use a more refined locking pin for adjustments on the TNT handle; and put some endcaps on the weight horns (cheap plastic amazon ones work but you could really brand those suckers).

The Hell Box is an extremely high quality add on for your belt squat. It makes it easier to load and unload plates, as well as improving your ability to maintain balance with the handle while not being able to cheat by pulling yourself up by the handles. I have mine configured to be as close to the end of the lever arm as possible to maximize felt weight, which is about 80-85% of the plate weight. The only disadvantage to that outboard configuration is your knees have to go on either side of the plates when squatting so you'll want thin plates to go heavy. The handle position has a ton of adjustment so it will work for any size person.
