Features

  • BEEFIEST SQUAT RACK - We decided to pull out all the stops and create the biggest, baddest squat rack we could at a price people could afford. The Chaos4000 is an absolute BEAST capable of handling the heaviest barbell in your home gym.
  • SAFETY SPOTTER ARMS INCLUDED - Every Chaos4000 comes with safety spotter arms in the box. It's advised to use the spotter arms when bench pressing or squatting alone, regardless of weight and our spotter arms will allow you to do so.
  • HEAVY-DUTY WEIGHT PEGS- You need somewhere to hold your weight plates and on the back of your rack is the ideal spot. It will keep your rack stable and make it easy to load up the bar. Each side has 3 weight pegs to hold your 45's, 35's, 25's and change plates.
  • COMMERCIAL QUALITY FOR THE HOME GYM - The Chaos4000 is capable of holding heavy loads and often. However, we designed it with features specifically for the home gym owner like a multi-grip pull-up bar for chin-ups, lined j-cups, spotter arms, black powdercoat, numbered uprights, and more.

  • Great rack, great value. Best rack I've found so far on Amazon
Style: Chaos4000
I actually had ordered a power rack (PR-4000) from RepFitness last year for Black Friday but it was on back order until God knows how long.. Ended up cancelling that order and saved a bunch of money after finding this power rack, after searching several dozens of other racks on Amazon. This thing is solid in structure and accommodating with respect to weight (plate) storage and overall space. I wanted a rack that I could not just squat with, but also bench press and barbell shoulder press with - this does just that. Assembly is super simple (might wanna invest in a impact driver if you haven't already to save A LOT of time), although I did end up running out of washers a little earlier than I'd hoped.. Would also prefer the plate holders (at least two of them) where slightly longer to accommodate more of my fat bumper plates, but everything is seated perfectly (I have x2 45's, x2 35's, x6 25's along with small 5's and 10's metal lbs plates). I just love that this thing stores weight plates with just 4 legs rather than the additional 2 legs (for a total of 6) which I'm use to seeing. Saves space and does the same thing imo.. Well done Grind Update: Regarding pictures, I used a steel drill bit to drill a hole into my power rack to attach a Titan Vertical Barbell holder as well as two (2) additional plate holders on the right side. It DOES have a barbell holder in the back left (used for my uneven curl bar), but access-wise, I think it should have been placed closer to the front and outside (like mine). Otherwise, so far so good.. ... show more

  • If you’re comparing benches, just buy this.
Style: Chaos4000
At this price point you’ll be hard pressed to find something better. It is extremely sturdy and feels like something that will last a long time. Aesthetic wise I personally love the color scheme and just the overall look of it. Pretty much everything about this is is engineered very well from the weight holders on the back to the bar/safety catches and the pull up bar. My first complaint is they advertise an extremely tough powder coating but after the first use the bar catches have been chipping away. I am generally very careful with my things and was about as delicate with this as you can be but even with mild clanging with the bar the paint on the bar catches keep coming off. Not a big deal overall though but I did expect it to be more durable. Secondly, the holes to insert the bar catches are 2 inches apart. While also not a huge deal there are some instances where one hole could be just a little too short, but then the next one could be slightly too tall. I’m not sure if this is common but it could be a problem if your someone who needs an extremely specific height. Set up was also surprisingly simple but you will need two people possibly even three if you want to be safe. Overall an excellent addition to any home gym and will honestly last as long as you want it to, even with its slight flaws this thing is amazing and would recommend it to anyone on the market. Unless you’re looking to spend an inordinate amount of money, this is your best bet. ... show more

  • Almost perfect.
Style: Chaos4000
I replaced a 2X2 rack with the 3X2 Grind Power Rack. I workout 4/5 times a week, so I see any flaws pretty quick. The Grind Rack was easy to assemble and is very sturdy. I have two problems with the rack. My old rack had the holes separated by 1 inch the Grind Rack has 2 inch separation. With the 2 inch separation, I feel like the holes are too high or too low for my squat and bench setup. The other big problem is the Grind Rack is about an inch to wide. I have an Ohio Powerbar and there is less than 1/2 inch clearance on either side. When I step out and rerack the bar, one side always hits. My old rack was about an inch narrower and it never gave me any problems. Another issue, not really a problem for me, Grind doesn’t have any accessories for their rack yet. I cut down my 2X2 rack and welded a top plate on the 2X2 post and installed it about an inch in-front of the rear support. I use it for all my accessories: split squat, dips, and an extra weight plate sleeve. I plan on drilling more holes in the 3X2 front post to give a little more flexibility with the J Hooks. I have a drill Gide and can add hole to make the 1 inch separation that I like. I have the tools so, it’s not an issue for me and the Grind rack is about $350 cheaper than a Rogue Rack. Even with the flaws, I would buy the Grind Rack again. If they were to update the rack with better spacing and a little narrower opening, it would be perfect. It is sturdy and holds my 400lb squat the same as a warmup 135lb. The pull-up bar is nice and the rack footprint is small and fits my smaller platform well. ... show more

  • Awesome rack!
Style: Chaos4000
Taking off a star because my rack was missing a few small parts. 2 screws for the rubber pad where you place the barbell. And it’s missing about 4 pressure washers which didn’t allow me to finish putting it together and had to go to Lowe’s. Quality control needs to do a better job making sure nothing is missing but the rack itself it’s made of good quality in my opinion. I really like it and recommend it just keep in mind you might have to go to Lowe’s for some small inexpensive parts. **UPDATE** contacted the seller regarding the missing/damaged parts and took care of everything really fast. Happy customer! I was going to keep my review 4 stars because I had to go out of my way but it’s hard not to the give 5 since the rack is so amazing and great quality! ... show more

  • Amazing
Style: Chaos4000
I’d been looking for a multipurpose rack for a few months now. I couldn’t find anything that checked off all my desires. This does that and more. It’s very sturdy. It’s even got mounting holes for the base if you want to make sure it doesn’t go anywhere but there’s no need. Assembly was easy. I did it with my four year old in about 90 minutes. It looks great! I can’t find a negative thing to say about this rack. My favorite thing is the plate storage like a gym. No other racks are this affordable and provide that, AND the bar storage in the back is a great addition as well. If you’re skeptical, don’t be. This thing is not too good to be true. But it quick before they realize they’re selling them for too cheap!!! ... show more
