Cuff Update For The Straight Cuffs ⬇️

February 1, 2022

After valuable user feedback, development and prototype testing, we can proudly present the polished version of the straight arm & leg cuffs the V2.1 cuffs!

For some of you this might be old news, as this was officially released last week, but in this post, we dig a bit deeper and present what the new cuffs have on offer.

Some of the changes are mostly of what we find “cosmetic”, but others are designated improvements of functionality and durability.

Below we run through ⚙️&🔩. So please beware of the ⚠️Nerd-Alert ⚠️.

🔩Updates concerning Arm & Leg Cuffs V2.1:

The backside material has undergone a major update. That is a new thicker TPU coated nylon which inhibit sliding of the cuff during exercise and seems to be extremely durable with almost infinite longevity.

The Cu-logo rubber patches are mostly for the looks, but if you get your hands on these You will soon discover it simply makes attachment and particularly detachment of the cuffs more intuitive.

🔩Exclusive improvement for the Leg Cuff V2.1:

To decrease pressure fluctuations during muscle contractions, we have implemented a more flexible internal core material. After testing several prototypes and researching on mechanical properties of different materials, we believe to have discovered a core material and thickness with an excellent blend of both stability, pliability and tensility.

In hand the Leg Cuff V2.1 simply feels more robust but also a bit softer to the touch.

Please let us know at info@fitcuffs.com what you think of this new design and do not hesitate if you have any suggestions for further improvements!?

Automatic Pressure adjustments during Blood Flow Restricted (BFR) Exercise – A randomized within-subject 8-week trial

Does auto adjusted blood flow restriction (BFR) training improve muscle growth and strength compared to fixed-pressure cuffs? In this first 8-week within-subject study using the Fit Cuffs BFR system, researchers found no meaningful differences in hypertrophy, strength gains, or perceived discomfort between autor and non-auto conditions. When pressure was prescribed relative to limb occlusion pressure (LOP) and training variables were standardized, both approaches produced significant improvements. Here’s what coaches, clinicians, and lifters need to know about auto vs fixed-pressure BFR.
