What are B3 BFR Bands?

The Greatest Breakthrough in Exercise Technology

Exercise in ½ the time, with ½ the weight and get better results!

B3 Bands are the result of more than 40 years of research & innovation, with over a million real exercise sessions.

Rooted in a scientific breakthrough utilizing Blood Flow Resistance (BFR) during workouts, this technique combines light exercise with the body's natural processes to give you amazing results that change the way you work out forever.

Studies have shown that when BFR is done correctly, it's just as safe as regular exercise. It's worth noting that BFR has been used safely in Japan for over 40 years! It's a tried-and-tested method that can help you get fit safely and effectively.

Not a fan of lifting weights or hard workout classes?

No problem! With B3 Bands, you don’t need heavy weights or grueling workout sessions to see results. Our Blood Flow Restriction (BFR) technology allows you to achieve the benefits of high-intensity exercise with light resistance and simple movements.

Whether you prefer walking, bodyweight exercises, or low-impact workouts like yoga and Pilates, B3 Bands help you build muscle, burn fat, and boost endurance—all with less strain on your joints and less time spent working out. Just 10 minutes a day is enough to experience incredible fitness benefits.

No gym, no problem!

You don’t need a gym membership to get in shape with B3 Bands! Our Blood Flow Restriction (BFR) technology allows you to achieve amazing fitness results from the comfort of your home, at the park, while you're traveling or anywhere you choose to work out.

With B3 Bands, even bodyweight exercises, walking, or simple movements can help you build muscle, burn fat, and improve endurance—without heavy weights or expensive equipment. Plus, with access to live and recorded workouts on B3 U, you’ll have expert guidance every step of the way.

Get fit anytime, anywhere—no gym required!

The Growth Hormone Effect

The Growth Hormone Effect

The B3 Bands work through a technology called Blood Flow Restriction training, or BFR. When you wear the B3 Bands, it naturally and safely slows down your blood flow in your arms and legs.

With less blood flow your muscles have less available oxygen. With less oxygen your muscles fatigue faster and deeper. This quick and deeper fatigue creates ‘the burn’ feeling in your muscles also known as lactic acid, which promotes a release of Human Growth Hormone after BFR exercise.

Muscles Fatigue Deeper

When you exercise with B3 Bands, they gently reduce blood flow to your muscles, which means your muscles get less oxygen than usual—similar to what happens during high-intensity exercise.

With less oxygen available, your muscles fatigue much faster, making you feel the "burn" sooner and activating more muscle fibers, even with lighter weights or lower effort.

This deeper fatigue tricks your body into thinking you're working much harder than you actually are, which leads to greater muscle activation, less joint stress, and quicker recovery.

In response, your brain sends a signal to release a surge of Growth Hormone immediately after your BFR workout, which is key for muscle growth and fat loss.

More Growth Hormone means faster results, better recovery, and added benefits like improved healing and anti-aging effects on the body!

Is this backed by science?

The B3 Sciences Advisory Board’s review of over 1000 papers, cases, studies, and peer reviews on BFR has shown:

“There is a robust increase in circulating growth hormone levels (GH) 30 minutes after a BFR session. The same exercise without BFR produces no increase in GH Levels. Positive effects are not just seen on muscles, but blood vessels, tendons and bone, as well”

“BFR Training performed with light weights is as effective as heavy weight training, when it comes to improving strength. To the contrary, using the same light weights without BFR does not demonstrate improved strength”

“Many USA Olympic, Collegiate, and Professional Athletes are now training with BFR and are performing better and putting less stress on their bodies”

“BFR exercise is a safe and effective exercise program for people of all ages including 8-80”

“Rehabilitation from injury can be done quicker and safer with BFR”

“BFR is being used for cardiac rehab for seniors to improve recovery and strengthening of the cardiovascular system”

“Endurance athletes, and people who like to do hard running or biking sessions, will benefit greatly from BFR. BFR reduces duration, lessens impact on the body, and shortens recovery time”

“Together we have over 70 years in the health, fitness and training industry. We have never seen anything like this!”
