F2 Bar & F2 Glute Bench
Do Professional Hip Thrusts at home...and MORE!

Our original F2 Bar was a big hit, but the cost to develop was too complicated for the price. So we put it on the backburner and went back to the drawing board. Then, while developing our new F2 Adapters* we realized there was a better way to not only improve the original F2 Bar, but also create an entirely new 2k20 Functional Fitness bench(less?). This is the result!

NOTE: Some of the videos still show our original F2 Bar as we're in the process of updating them with the new F2 Bar 2.0. All purchases will be for the F2 Bar 2.0.

Customer Testimonials

Joe Kiyose Ifbb Pro

It's a creative all-in-one solution

"...its innovative design which allows you to easily clip on bands and chains, I think its a very useful piece of equipment. Particularly, for those who use isometrics, resistance bands and body weight exercises. And for the hardcore weight lifters who still want to use weights, this barbell allows you to do so. It's a creative all-in-one solution".

F 2Bar Testimonial

So I really like the bar.

"I ended up having to put it in at work at a wider door opening with metal frame.  I have been using it as a solid mount for a multitude of exercises.  The photos are of my student working on resisted lunges and resisted jumping."

Holy crap, thank you!!!

I don't usually gush over workout equipment, and yours is outstanding!!! Seriously, first off your customer service was great and I see why, because your product is outstanding!!! Well made, solid construction and attention to detail of your product!!! At first I thought the bar was a bit long, but once I attached one of bands, spot on the money!!!

Please send me more information about the rest of the products. Honestly imj not many people make something the well!!!

F2 Bar Testimonial

Solid, versatile, ingenious product!

I waited a bit to get it, but it was definitely worth the wait. It's solid, versatile, and a perfect fit for my small gym set up. I don't have room for a lot of plates for squats and looked for days for the right bar. I wasn't sure if what I was looking for even existed. At first I considered the bar used for portable pilates, but they are not a match for my goals. I needed something that could hold up to a lot more stress.

My first workout with the olympic resistance band bar, I thought if I put too much pressure on the bands while doing squats, the clips would give and I might even end up hurting my back. I was happy to be wrong about that. I feel more comfortable now after putting it to the test on a few exercises for the past 2 weeks: squats, military press, curls, pull-ups, bench press. I couldn't be happier with my purchase. I'll post an update after a few months regarding durability.
