      As previously stated by others I've researched several models and versions of power racks. I needed an upgrade to support my aspirations for continued fitness. I kept returning to the C-4000 as it compared nicely to the other brands. Additionally, its features and quality of frame and accessories were unmatched when also factoring the price. The design is nicely constructed as well, providing for unlimited exercises to easily perform. Customer services is also great. My order was processed efficiently with a short delivery time. They also quickly expressed mailed additional hardware (e.g. washers) that was missing. Good company and good product.

      Great Setup for my Home Gym

      Like many others that have left reviews, I was debating on whether to go with Grind equipment or a more expensive product. I was worried that the Grind rack might not be solid enough. In the end I went with Grind and I'm so happy I did. If I would have gone with the other company it would have cost me another $1,000 at least. Choas4000 Half Rack is great, got the Grind Force barbell and Fleck Crumb Rubber Bumper plates. Many have mentioned that there isn't padding on the spotter arms... and I agree that this would be nice. I actually use the spotter arms to set my barbell on when doing shoulder presses for example, so having the padding there too would make sense instead of scratching up the metal. But not a major deal to me. The one other thing mentioned by some others is that the barbell (at least my Force bar and it seemed like others as well) is a little tight fitting and as you're pulling the bar off or setting it back on the j-cups it's easy to not get it set properly. Shortening the rack by just an inch or so would certainly have helped with that. But not a deal breaker for me. Was debating on what plates to get and I'm very happy I went with the Fleck Crumb Rubber Bumper plates. Easy to get on and off, won't bang up your floor, and nice looking! I'd still buy the whole package again if I had to do it over!

      Excellent for the job!

      Simply a great deal. Bought this rack for my fitness studio to save space. Nice solid piece of equipment and it does the job for what I need. Shipping was fast and easy assembly.
