Our primary aim with Fit Cuffs is to let all people experience effective, safe, and convenient BFR Training by means of a top performing One-Size-Fits-All device.

Blood Flow Restriction (BFR) Training aka Occlusion Training is maybe the most important discovery for decades in the world of strength & conditioning and importantly musculoskeletal rehabilitation. The potential benefit and avenues of BFR are relevant for Prehab, Rehab, Performance, & Maintenance.

Regardless of profession, limb size, gender, or age, You will have the possibility to combine all components from the current and forthcoming products. For future product innovations and upcoming designs, we will retain the industry-leading metal connector and One-Size-Fits-All dogma. So, Fit Cuffs is both designed with special emphases on durability and thereby several years of longevity with the ever lasting possibility to expanding on Your assortment. So, if you’re a health care provider or trainer, You actually only need one “Complete” set to start Blood Flow Restriction Training for all applicable clients.

The research in BFR is progressively expanding by 2023 and Fit Cuffs is all about applying this science to clinical practices with convenience in mind. We do this by continuously innovating the product selection with the latest being the V3.1, consistently staying state of the art. During the development of the V3.1 Cuffs, we successfully combined the most current Science in BFR Training, internal product testing, and valuable user experience to create the marked leading BFR cuffs.

With an emphasis on convenience, we have developed a dedicated web app with several different modules all of which can be of relevance for Blood Flow Restriction Training. Note worthy is the “Calculate Pressure” module at training.fitcuffs.com, which lets the user attain a valid and personalized pressure (mmHg) recommendation.

Our customers vary from clinicians e.g., physical therapists, chiros, strength & conditioning coaches, personal trainers, or just individual use. Worth mentioning is that several researchers are currently applying Fit Cuffs, primarily because of the scientifically validated LOP Device for assessments of Limb Occlusion Pressure (LOP) aka Arterial Occlusion Pressure (AOP).

Fit Cuffs® Training System vs. Similar Products

Below is listed some of the reasons why we find that Fit Cuffs is superior to other similar BFR systems


1. One-Size-Fits-All

Unlike other brands where you have many different sizes and you have to buy several different cuffs, Fit Cuffs is true One-Size-Fits-All. Our default cuff size will fit approx. 99% of all people with only one version for the upper and lower body, respectively.


2. Curved & Straight Cuffs

Leg Cuff V3.1 – curved cuff with a wide velcro attachment area that allows for a custom contoured cone fit. This variable-contour cuff can be adjusted to the shape of the thigh, providing an optimized and personalized fit for optimized pressure distribution during exercise.

Leg Cuff V2.1 – the updated straight cuff is designed with a cylindrical shape that fits most people regardless of thigh shape.

3. Improved width of the Cuffs

The width of the cuffs is somewhere in-between other brands, as there is nothing as perfect-sized cuffs, but pros and cons to all designs.
But a newly published review on the perceived discomfort during BFR Training, concludes that particularly in the upper body, narrower cuffs are favorable as wider cuffs seem to increase ratings of discomfort compared with more narrow cuffs. Spitz et al. (2020) Blood Flow Restricted Exercise and Discomfort: A Review
Narrow cuffs allow for more freedom of movement even though pressure must be a bit higher compared to wider cuffs. The problem with wider cuffs is the muscle tissue directly underneath the cuff experiences less hypertrophy compared to the rest of the muscle. Thus the favorable mechanism is to compress a small area, on the other hand, a narrow cuff has higher pressure gradients (fluctuations) during muscle contractions. See the figure from McEwen & Casey (2009) for further explanation (cuff type A & C).


5. Limb Occlusion Pressure with the LOP Device

It is commonly recommended to use a percentage of Limb Occlusion Pressure (LOP) / AOP, usually assessed with a hand-held doppler. With Fit Cuffs, you have the possibility to use the LOP Device for fast, precise, and convenient assessment of LOP.


4. Differentiated pliability

Fit Cuffs is the only system that uses differentiated pliability. Higher pliability for the upper body cuffs, as the muscle expansion of the biceps, is relatively larger compared to the thigh muscles. Some companies have rigid upper body cuffs, which can cause tissue damage, as the rigid cuffs won’t allow for muscle expansion during contractions. See the figure from McEwen & Casey (2009) (cuff type B vs C).


6. Best durability on the market

We are proud to tell you that our product return rate is below 1%, as shown by our satisfied customers at trustpilot.com.
Fit Cuffs utilize an exclusive metal quick-connector, that is extremely durable as opposed to the disposable plastic connectors used in similar brands. This unique quick-connector also enables re-connection with the Fit Manometer (pressure gauge) without pressure loss during exercise. As opposed to the plastic connectors used by similar companies where the pressure will drop during re-connection with the pressure gauge. The rather simplistic design of Fit Cuffs makes for the best longevity on the market.


7. App module – Fitness Calculators

This feature can be assessed at the progressive web app “Fit Cuffs Training”.

One Repetition Maximum – By the 1RM module, you can estimate your repetition maximum with a submaximal load, or just enter your known 1RM, which is relevant for resistance training combined with BFR.
Aerobic Fitness – This module features 4(3) different tests built into one module. Here You can estimate Your VO2 Max, Fitness Level, and Watt Max, which are commonly known as “indirect tests” of VO2 Max. The tests can be performed on any type of exercise bike. Subsequently, you can use the built-in slider to set the intensity relative to either Watts or Beats Per Minute (BPM) relative to Your Heart Rate Reserve (HRR). 



8. App module for calculation of individual pressures

This feature can be assessed at the progressive web app “Fit Cuffs Training”.

As a convenient alternative to LOP, You can use the “Calculate Pressure” Module to attain an individual algorithmic-based pressure (mmHg) recommendation. Please consider using the measurement tape, because limb circumference is the strongest predictor of LOP and the corresponding pressure calculation. Mind that the algorithm has been calibrated to Fit Cuffs in regards to width and pliability, and we do not recommend using it with other cuff types.

Engineered for Evidence-based Blood Flow Restriction Training

With Fit Cuffs you get a device exclusively developed for occlusion training a State-Of-The-Art. In only 10-20 minutes (including cuff attachment and detachment) you achieve a workout comparable to 30-45 min of conventional exercise relevant from Prehab to Rehab Performance & Maintenance.

Our primary goal is to create a product that is effective, safe and convenient, developed from the current science in Blood Flow Restriction Training. We have designed the product in such a way that it fits all people regardless of limb size, so if you are a physical therapist or a trainer you only need one set to service all of your clients!

Yes, you only need one complete set of Fit Cuffs to prehab, rehabilitate, improve performance or maintain muscle mass for everyone to achieve their goals!

When you buy a complete set of Fit Cuffs you get a professional product that is tried and tested on +1000 people of all ages, a product that takes up less space than a pair of trainers!

Fit Cuffs utilizes probably the best inflatable cuffs on the market and a unique and extremely high-quality metal quick-connector, this makes the process of inflation and deflation swift designed for optimal convenience.
