Product Features

  • CLASSIC 4-POST RACK

    This 4 post power rack is the granddaddy of all rack configurations. Laser-cut numbers to easily line up rack attachments. Beastly 1,000-pound capacity and ultra-stable 11-gauge tubing. Everything you need to tame (or unleash) the mythical beast within.

  • CROSS-BRAND COMPATIBLE

    Don't let brand limitations hold you back! The Hydra features industry-standard tubing & hole sizing, so you can freely use matching-spec rack attachments from other brands. See? You don't have to swear allegiance to us forever.

  • NEVER UPGRADE AGAIN

    You know what they say: buy once, cry once. The Hydra is highly customizable with its modular components, so it can adapt with you through every phase of your life. It's the last rack you'll ever need — which takes the sting out of the investment.

Product Details


The 4 Post Power Rack is to home gyms, what maple syrup is to Canada: world-renowned, and the sign of impeccable taste. *chef's kiss*

It outlasts heavy squats, handles big bench presses and withstands chin-ups with 8 kids hanging onto your waist - just bolt it down before you go trying for that new chin-up PR. The uprights 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, you can mix and match attachments freely without needing to stick to one brand - hello, open ecosystem! Built with modular components, so you can expand later with Hydra components or divide it into two smaller Hydra racks to accommodate a new home gym space or team workouts with your swolemate.

Compatible with all Hydra rack attachments, like the hyper-versatile Hydra Lat Pulldown.

Awarded Garage Gym Reviews' Best Squat Rack with Pull-Up Bar in 2024

IMPORTANT: The Hydra series of power racks are TRUE 3" x 3" tubing with 5/8" holes, so only Hydra attachments & non-B.o.S. attachments made precisely for 76.2mm x 76.2mm uprights with 5/8" holes will fit.

    Surprisingly good for a lot less

    Upgraded from a 2x3 rack to the BOS Hydra and I have to say, it’s far better quality than what the images convey. Powder coat is very good as are the laser cut holes save one (1 hole wasn’t completely cut out but BOS immediately replaced the crossmember).

    It really is a fantastic option and my only gripes are quite minor.

    The bolts should have 2 washers as I bought extras to prevent the split washers from chewing up the beautiful powder coat. That should be a no brainer on BOS part and they could offset the cost simply by using a smaller OD on the washer as the BOS ones are huge.

    The attachments (J-cups, spotter arms, etc) should be upgraded to have UHMW liners vs bare powder coat. Even Titan Fitness lines theirs.

    And I would prefer the base plate on the uprights to be square to help with stability vs the rectangular plates they use (the same plate on the crossmembers). I get why they use the same plates for cost savings and it does make the packaging easier keeping them flat but I prefer square base plates.

    Again, minor tweaks but nothing that detracts from the beastly-ness that is this rack. Highly recommend!

    Hydra Rack - 108"

    Great "CAGE"...not many options for >100"...able to add heavy bag due to increased height capability...also added two plate-loaded towers...squat rack on one-side and functional trainer on the opposite...complete walk through system. Stay safe.

    Awesome equipment - very happy

    Great experience. Found everything I needed to get the home gym off the ground. The YouTube videos for building everything was really helpful and quality is exactly what I would expect.

    I bought 2x barenaked bars, the 4 post hydra, buzzsaw bench and a couple other attachments and safeties to round it out. Would definitely recommend.

    Excellent value!

    I saved money by picking the rack up in Toronto. This is a tank of a rack. Pictures do not do it justice. Its overbuilt in a good way. My kids are now working out with me, which is a blessing. So happy ti support a Canadian company doing good work!

    Sincerely,

    Marcus & The BoS team

    Absolute unit

    Very happy with my hydra rack. After using a cheap rack for several years I decided to upgrade to something more substantial. This is a very sturdy rack, the 3x3 uprights and 11 gauge steel give it a commercial gym feel, and the black powder coat gives it a high quality look. I purchased the bolt on straight pull-up bar and the dip attachment and am quite happy with the quality. I also appreciate that the uprights and crossbeams can be purchased separately, in the future I plan on turning my 4 post into a 6 post rack. The customer service is also fantastic, they were very responsive from my experience. The packaging was all high quality, nothing was damaged on arrival. I live locally but shipping was quite fast, my order arrived 3 business days after ordering.
