Dual 289-lb Stacks Deliver Smooth 2:1 & 4:1 Pulley Control

The Force USA G15 delivers commercial-level performance without crowding your space. It’s the first with interchangeable 2:1 and 4:1 pulley ratios—versatile enough for heavy lifters chasing PRs and families just starting out—while dual 289 lb stacks give you the edge from day one, up to 45% heavier than competitors.

It starts with a Power Rack base, then adds a Functional Trainer and counterbalanced Smith Machine for all skill levels, plus a Chin-up, Low Row, Lat Pulldown, Dip, and Suspension Trainer. Band pegs let you push past the stacks, while a heavy-duty frame and stabilizers keep every station rock solid through your hardest sessions.

The details drive it home. A low-frame design with stabilizer pads keeps everything rock-solid and wobble-free. Optional four-shelf storage, two barbell holders, and eight plate holders keep your gear organized and your floor clear. This is what happens when engineers lift—this is the G15.

With the G15, Your CORNERSTONE® Is Set

The G15 isn’t just an All-In-One—it’s a CORNERSTONE® Trainer, the foundation your entire gym is built on. If it’s not from Force USA, it’s not a CORNERSTONE®. It’s the only option with adjustable 2:1 and 4:1 pulleys—built to train everyone under one roof.

This is where performance gets personal. Sixty laser-etched, one-inch spaced adjustment points on the uprights give you perfect placement for any lift without the guesswork. Everything locks into place exactly where you need it, whether you’re pressing, squatting, or pulling.

When you’re ready for more, the G15 is ready too. Add Jammer Arms, a Vertical Leg Press, Lat Pulldown Seat, Leg Extension/Curl Attachment, Storage Shelves, and more to make it unapologetically yours. From precision adjustments to upgrade-ready design to more storage solutions, the G15 doesn’t just keep up with your training—it evolves with it.

Finally, a quality build seals the deal. Quad-bearing rollers keep the Smith bar smooth and consistent, while the heavy-gauge frame shrugs off your hardest sessions—and it’s all backed by a lifetime warranty. It’s details like this that make the G15 an investment you’ll never regret!

The G15 comes fully loaded with essential attachments and gear, with room to upgrade when you’re ready to take it up a notch—or several.

Reviews

I love it, but wish I'd bought the G20

"Overall, this is a fantastic piece of equipment. I've had mine for a couple years now, and I use it 3-6 times a week. I have Jammer arms, leg extensions, and other attachments. I'm able to do pretty much any exercise. My only complaint is with the Lat pulldown piece--to get enough weight with the Lat pulldown, I have to sit on the floor (because the equipment isn't tall enough), and use both sides' pulleys. But the attachment to keep you anchored on the ground is specific to a side, and isn't centralized for the equipment, so it makes it very difficult to load enough weight for Lat pulldowns. Sometimes I wish I'd gone with the G20. Overall, though, I love this equipment."

PERFECT PRODUCT

"This has been a game changing additional to our clinic. I'm not sure it has had a rest since being built!"

Jayden (5/5)

G15

"Shipping was terrible, terrible, terrible. They lost 2 of the 3 boxes. By the time I got everything it was over a month. After several phone calls, Force USA sent missing items. It wasn’t their fault so I didn’t take any stars off. The G15 is great. It took several days to assemble but we really like it. The quality of the equipment is very good. I also ordered the upgrade kit, a bench, and plenty of weights. I’m very happy with my decision. The wife and kids are using it as much as I am. I chose the G15 over the other all in ones because of its quality and looks. It’s the center piece of our garage gym so I wanted it to look nice. I like the way the weight stacks are tilted toward the center. The upgraded pulleys give it that high quality look. I have recommended force USA to family and friends"

Worth EVERY penny!!

"This unit is incredibly sturdy! Works great for my 6’ 4” husband. I can barely use it myself, he’s on it non-stop HAHAHHA. We have it set up under our garage track and it fits like a glove, no issues with the garage door functionality. The team hired to set up the system was also incredibly efficient, professional and kind. We didn’t opt for them to remove the garbage (crates and boxes) but wish we had after the fact but that choice was on us! I HIGHLY recommend this system to everyone looking for a home gym!!"

"Gym quality all-in-one piece of equipment"

Shane (5/5)

Love love love!

"Exactly what I was looking for and more. The multiple rations and zero resistance smith bar allow the whole family to use it. Perfect for little athletes working on strength to support their on the court/field goals. The company who were contracted for install was horrible though!"

Megan C. (5/5)

Beautiful equipment, terrible manual

"Great quality equipment but some of the worst assembly instructions I have ever seen. Some of the depictions have way too much going on and should be broken down even further. Also I ran into numerous mistakes with the parts needed (bolts, washers, etc) for many steps. Also I purchased the G15 add on which really wasn't worth it aside from the jammer arms and storage racks, the other items are duplicates that already came with it. Other than that the equipment is very nice quality"

great but. . .

"this was an amazing buy n it works great! been using it for about a month n i have no major issues with it! my biggest complaint is it isn't made in the USA. that was one of the key things i was looking for and must of not digged deep enough about the company so that's on me. but that being said the instructions are clear but some item labels and quantities are wrong or not labeled but if u have ever done a puzzle of any kind u can fill in the blanks no problem. my second complaint is that my item shipped with a piece missing and a whole not being properly punched in the frame for bolts. now im only talking about one of each so their quality control is pretty good but after paying close to 6,500 u would think there would be looked over better. all n all an amazing product and company! help is their when u need it and it ships amazingly fast!"

G15 Home Gym

"Purchased this for my new home gym. Arrives as described, only missing 6 lock washers after complete install, not bad for such a large machine. Took me about 12 hours to put it all together by myself, other than my wife assisting me with the 2 weight stacks. After it is all said and dome still need to figure out the cables and stacks, as the install directions were not to clear. . . . . Speaking of directions, the paperwork instructions are outdated for the G15 rack, I downloaded from the site and these instructions ere updated with the new pully sizes and bolt placements. . . . big help. Have used the equipment for about a week now, still waiting on the bench and free weights to get here , hopefully in the next few weeks. . . . then we will test the rest of it!! Solid equipment so far"
