What is BFR


Bands are the product of 40+ years of research, ingenuity, experience and over 30,000 real life exercise sessions!


The  Bands are based on a scientific discovery in exercise that uses BFR (Blood Flow Resistance). This process uses the body’s natural systems in combination with light weight-training to produce results that will change the way you work-out forever.


Don’t worry, it is safe. Blood Flow Resistance has been used safely and effectively in Japan for over 40 years!



The  Bands use Blood Flow Restriction training, or BFR. When you wear the  Bands and do light exercise, you create a natural and safe manipulation of the body’s circulatory system.

While doing light exercise with the  Bands on your arms or legs, the blood exiting out of your venous system is slowed down. This reduction in blood flow out of the muscle while doing exercises causes the muscle to fatigue quicker and with a lot less work.

When a muscle fatigues, it creates signals to your brain that results in a surging hormone release. These hormones then trigger any muscles worked to adapt.

This hormone release has many other anti-aging and rejuvenation effects on your Body!

BFR Exercise Physiology



What happens in my body when I use B³ Bands during training?


  • Light exercise with B³ Bands produces a quick and easy muscle fatigue.
  • A fatigued muscle sends a signal to the brain that a metabolic change has occurred. You feel the muscle burn; your brain takes action.
  • The Pituitary Gland releases a rush of Growth Hormone (GH). GH is the most powerful hormone in the body.
  • The body responds to this GH release by secreting other hormones that create positive changes in muscle after exercise.
  • This GH hormone surge also creates a whole host of other health benefits in your body. (Anti-aging, cardiovascular, bone, and many other benefits)
  • Because you have used light weights or have done light exercise, the recovery time will be reduced.
