F2 QuickHIIT

Who F2 Equipment is NOT For
Those that get easily frustrated assembling things like Lego sets or IKEA products, ALLN-1 equipment is definitely not for you. Your time and desire, to solve problems using basic DIY solutions is the tradeoff between personalized fitness equipment vs. cookie cutter equipment. Please take this into consideration before purchasing any of our ALLN-1 F2 products.

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.

About the Inventor of the ALLN-1 Product Line

Having spent over 30 years in fitness as a life long natural bodybuilder, personal trainer and fitness consultant, the next challenge I wanted to take on was to FINALLY develop intelligent fitness equipment, by combining my years of experience ALLN-1.

(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".

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!!!

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!
