The Most Advanced All-In-One We've Ever Created

The CORNERSTONE® of the Elite Gym
C20 All-In-One Trainer

C20 All-In-One Trainer

$6,499

Two decades ago, Force USA pioneered the world's first All-In-One home gym built around the power rack. Since then, we've earned numerous patents, industry awards, and the trust of over half a million customers worldwide.

Today, we're raising the bar one more time.

The C20 is the most advanced, purpose-built training system we've ever created. Every dimension, every connection point, every pulley ratio was engineered with a single goal in mind: to be the Cornerstone of the most capable home gym you've ever trained in.

Weight stacks that scale from 200 to 300 lb, future accessory compatibility, and a multitude of integrated stations beyond the rack and functional trainer mean the C20 delivers the kind of versatility that once required an entire commercial gym floor.   

And we didn't stop at performance. The C20 is as sharp-looking as it is capable, with integrated storage that keeps every attachment organized and within reach, because a gym this good deserves to look the part.

The deeper you dig, the better it gets. Keep scrolling.

FAQs
The C20 is the 3x3 evolution of the C10. Same core functionality, but built to flex harder. It’s beefier, more customizable, with features like pegboard and shelf storage you won’t find on the C10. The dual weight stacks are upgradeable and come standard with premium Aluminum attachments. This isn’t a makeover—it’s a full-blown transformation.

Reviews

C20 Review

"Excellent all in one trainer. Took about 8 hours to assemble by myself. Pretty straightforward. Everything lined up very nicely, machining, and finishing were excellent. I added the swivel lat down seat, which is a must for that movement. I also have some other brands of add-ons I use. Overall a great piece of kit for your home gym!"

Stephen D. (5/5)

We love our new gym.

"We love our new gym. Haven't been back to the commercial gym since I put it together. The convenience of commercial quality equipment feet away from your bedroom eliminates excuses. I bought it for my high school athlete, but end up training neighbors that walk by the garage to see what all the fuss is about."

Armond J. (5/5)

Fantastic

"I have found when buying things it's better to spend a little more for quality. The C20 did not disappoint. From the welds, smoothness of the cables to the fit and finish. This trainer is outstanding. It is such a pleasure to work out on the C20 every time."

Greg G. (5/5)

Top Shelf

"Extremely well thought out, smooth and has more than everything you need in a home gym."

Chad L. (5/5)

Amazing!

"I’m so glad I bought this! My daughters are using it. I’m using it. That machine is well built and is beautiful. It was fun putting it together. I have wanted an all in one machine from Force USA for a long time. I’m glad I finally got one. Money well spent."

Brandon M. (5/5)

Love it!

"Pulleys are very smooth and so is the smith machine. Nothing about this machine feels cheap. I've used it for about 3 weeks now and I love it! I did put it together by myself so it took me about 14 hours total over a couple days. I would recommend using the instructions, plus watch a youtube tutorial video on assembling the c20 while you do it. Thats what I did and it helped a lot on a couple steps. The assembly wasn't to difficult though. An extra set of hands on a couple steps would help, but for the most part it can be done alone. Love the c20!!! Glad I bought it!"

Andrew W. (5/5)

C20 - mostly happy with it

"This machine is a significant investment and before you purchase, be aware of these things: The paint on this machine is extremely brittle. A good amount of parts of the powder coating was chipped during shipping. But the paint will also wear during normal use. The sliders from the cable arms on the uprights wear on all of the edges, there seems to be a design oversight where the bottom pin underneath the arm grinds on the foot of the machine when it’s in the very bottom position, leaving a half moon shaped scrape on both sides. The barbell ends on the smith machine are smooth powder coat. Even smooth bumper plates will tear up this finish. You do get a good variety of attachments included, but I feel like they can be improved as well. They are high quality, but basic. While I am happy with the functionality of the components of the machine (cables & smith), I feel like there is a lot of improvements that should be made to make this worth the significant price tag."

Christian F. (4/5)

Love my C20

"Love the machine. I am able to do my full chest, shoulders, legs, back, and arm workouts with the machine and my adjustable dumbbells. The leg press, extensions and curls have smooth motion, and even distribute the load throughout the range of motion (instead of having stick points or parts of the motion that are more difficult)."

Daniel S. (5/5)

Best of the best!

"Was looking for something that could grow with me and my family and this machine just met all needs. The quality is amazing. The sleek design just makes my home feel more luxurious. The machine itself opens up so many exercises and fun ways of doing things I used to do on multiple machines. When I have kids, I can train with them near me when they are little and as they get bigger we get to do family workouts. It worth the investment and so many memories will be held here"

Sally l. (5/5)

Pretty good with some notable misses

"Let’s start with set up. The directions included with it are absolute garbage. They are poorly drawn and sometimes downright contradictory. There is a video on YouTube that details the build. Without it, I would still be building three weeks later. The sliding bench instructions are even worse and the pieces are not labeled at all, no video that I could find on that one. So had to muddle through it. So that may taint my view of the machine in general. The c20 itself is ok. Probably not worth the money. To set up the sliding bench to do legs or change it around takes more time than the workout. There are 3 different sets of cables that you have to use. The leg extension is not even worth the madness of setting up. Bad design. The rest of the machine is just all the things you would expect from a cable machine. All in all. It’s ok."
