The B STRONG Training SystemTM was created with safety and efficacy in mind by Dr. Jim Stray-Gundersen, Sports Doctor, Exercise Physiology and Trainer for Sport Performance. B Strong is specifically designed NOT TO OCCLUDE (stop) blood flow to the limb, making it the safest BFR system of its kind and can be used anytime, anywhere by anyone to optimize overall fitness.
As this doppler ultra sound video shows, the B STRONG Training SystemTM uses uniquely designed bands that maintain arterial inflow when safety rules, cautions, and app guidelines are followed. On the other hand, blood pressure cuffs and surgical tourniquets, which have sometimes been used for BFR training, occlude blood flow to the limbs. Avoiding occlusion of arterial inflow to a limb mitigates against the root cause of serious complications.
We do not recommend a pregnant woman start B STRONG TrainingTMsessions during her pregnancy. Seek the advice of your doctor if you have other concerns about B STRONG Training SystemsTM during or after pregnancy.
