Benefits of the Hydra 3" x 3" Half Rack

    This half rack is the beautiful offspring of our 4 Post Rack and Squat Stand. Space-efficient, highly versatile, and devilishly attractive. The flat foot design maximizes stability and with the option to use the rear uprights for weight plate storage, you can save valuable floor space (#winning). Or flex your traditional muscles and keep all uprights attachment-free, performing two different barbell exercises on the front & rear uprights. The superpower of this half rack is its adaptability to your training needs.
    If you’re a die-hard fan of the metric system, then listen up: the uprights of our Hydra racks measure true 3″ x 3″ which is EXACTLY 76.2mm x 76.2mm, instead of the typical 75mm x 75mm uprights of other brands’ imported racks. By matching the same tubing specs as many of our American competitors who make their racks on US soil *respectfully tips hat*, you can mix and match attachments freely without needing to stick to one brand — hello, open ecosystem! Just be sure to research thoroughly BEFORE you begin the mingling shenanigans, deal?
    QUICK! Name three things in life you can’t live without. I’ll go first — pockets, sliced bread, and… a customizable power rack 😎 Choose a pre-made design like you see here or build your own piece-by-piece. You can always add separate components later when you’re ready to expand your unit with weight plate storage, or divide and conquer by splitting your rack into two collegiate-style racks for double the fun. As you can see, we put a lot of thought into this… our mom would be SO proud.

More AWESOME features on the Hydra 3" x 3" Half Rack

Hefty 11-Gauge Steel

Hefty 11-Gauge Steel

Built with 11-gauge steel, this bad boy can handle the weight capacity needs of world-class lifters. You get even more stability than our Light Commercial Rack which means less shaking when racking your bar or while using attachments. Even if it’s not bolted down, you’ll feel that true #heavyweight status.

Laser Cut Numbers

Laser Cut Numbers

Trying to line up your j-cups perfectly can be a pain in the you-know-what. And unlike many of our competitors, we have lasered numbers every 1-2 holes to make adjustments a breeze. So you can easily change your j-cup height after your widow-maker squat set… because counting is HARD WORK when you can barely breathe.

1" Spacing in Bench Zone

1" Spacing in Bench Zone

Ready to settle for 2″ hole spacing throughout? Pffft, not a chance. You are an efficient and optimized MACHINE, that’s why we went with extra precise 1″ hole spacing to make unracking a heavy bar a little easier. After all, every morsel of energy matters when going for that 1lb PR (fractional plates, you da real MVP).

hydra half rack as a lot of squat space

No Spotter Needed

If you train alone, then you know what it’s all about: your own music, no line-ups, and curls in the squat rack. However, it’s essential that you train safely and that’s why every Hydra rack comes with your choice of pin pipe safeties, safety straps, or spotter arms. You should NEVER hesitate to dump a loaded barbell if needed.

First time BoS Buyer: Good Overall experience

My review reflects both the Hydra Half Rack, as well as my over-all BoS experience being a 1st time buyer. Ordering experience: (1/5) There is a lot of room for improvement here. The over-all UX of the BoS website is very poor. I found the website to be very slow due to what seems to be a lot of background JavaScript. Add something to cart, and wait several seconds for that item to show up. Want to add a coupon from the cart page? Nope! This wouldn't be a challenge for someone who knows what they want, however this being my first gym rack, I spent a considerable amount of time going back-and-forth, configuring multiple racks, options and packages to find the best fit for my needs, AND the best deal. My suggestion is to implement a config wizard that would help noobies like myself find the best package based on their needs and budget. I ended up bundling the bar with the rack to save on the bar, and pricing out the plate set separately to get the best over-all price. Furthermore, the layout of the website is also less than ideal. You have to do a lot of up and down scrolling to get key information on your products. Fonts are too large in certain areas, paired with unnecessary graphics and visual elements that just clutter the layout. Over-all the website was rather frustrating to use and almost drove me to a competitor. Shipping/delivery: (3.5/5) Disappointingly, the rack took longer to ship than advertised. I wouldn't mind, as long as the delays were communicated clearly, which they weren't. I felt like I had to hound the BoS team for an update to get any information. Not a great feeling after spending several thousands of dollars; trust starts with good communication. Once in possession of the carrier, everything went smoothly. Packaging/unboxing: (4.5/5) Everything was wrapped up very well and protected during shipping. I would prefer to see less plastic if possible. For things like rubber plates, ditching the plastic bag could perhaps help reduce the smell further. Assembly/instructions: (4.5/5) The Hydra Half Rack was very easy to put together. Everything lined up perfectly, all the hardware was machined without defects, over-all an enjoyable process. Half a point lost as the website does not provide Hydra rack instructions. I wanted to find a PDF to zoom in on, but couldn't. YouTube is not my thing for things like this. I would also suggest mentioning socket/wrench sizing in the instructions, unless I missed it. Fit & Finish: (5/5) The rack is fantastic: it is very well built, sturdy and looks good. The included hardware was void of any sharp edges, machining defects or otherwise. Everything fit like a glove, well done!

Awesome Rack

The Hydra hall rack is a work of art; the build quality is second to none; the accessories that you can put on this rack make it a total workout unit that functions perfectly. The accessories I chose were sliding lever arms, lat pull down attachment, multi grip chin up bar with globe grips (awesome), dip stand (awesome), sliding j-hooks, I highly recommend this rack and the accessories that I have listed.
