+ F2 Modular Gym Seat + F2 Sandbag
& F2 Straps Package

When most people think of hip thrust, the first thing that comes to mind is butt exercise equipment. However, anyone with a pelvic floor should be doing some type of pelvic exercises with hip thrust equipment, because as we get older our pelvic floor weakens. Our patent pending* F2 Modular Gym Seat will allow you to perform numerous variations of pelvic strengthen exercises in addition to popular hip thrusts for developing glutes.

In addition to our F2 IsoResistance Platform, F2 Bar and 2k20 VH Seat we offer other innovative forms of progressive resistance options that are intuitively designed to work together--to ensure you get maximum REUSE out of all your ALLN-1 Functional Fitness products--while at the same time, saving you MONEY! It's the most efficiently designed home gym equipment available.

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.

Barbell Ab Crunch

Customer Testimonial

(VRS) clips into the rotation to help dial in the tension I’m looking to achieve

The VRS clips added to standard 32” or 41” bands really provide the minute increases that using bands alone is hard to achieve. Triceps-32”SS green Kickbacks-41”Quantum orange w/RB handles

FS-31”SS green w/TrainChange Fitness VRS clips (this really added the tension I wanted at the top without making the entire tension curve too much on the e eccentric portion)

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!!! [F2 Barbell]

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 im 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.

I love them [ChainBeasst]

I have these and use them to attach bands to my barbells. The collars themselves are strong..

I can use both free weights and bands at the same time. I used them for the first time about two weeks ago...The strength curve was perfect. When I first grabbed the bar I thought, holy sh*t...I wasn't sure I could curl it once. I was able to squeeze out 8 reps and every inch of every rep was brutal!
