How does B Strong compare to Owens Recovery Science System?

B Strong is affordable ($429.95 MSRP for 4 arm and leg bands vs. $7,000 for one Owens cuff), comfortable, safe and effective BFR system that can go anywhere, be used by anyone, for any activity, where Owens tourniquet must be monitored by a therapist

Using 4 Bands Simultaneously

It is perfectly safe to use all four B Strong bands simultaneously. It should be noted that using 4 bands at once can make exercises more difficult. When people use all 4 bands simultaneously, they generally finish the session sooner (~15 minutes). W

Muscle Glycogen

BFR exercise uses muscle glycogen as the main source of fuel to replenish intracellular phosphate stores.  Because blood flow restriction limits delivery of oxygen to working muscle, anaerobic metabolism must take over replenishing ATP/CP.  The only

Ketogenic Diet (Low Carb)

Ketogenic Diet (low carb) diets do not allow you to maximize benefit from B Strong sessions (or really any exercise).  B Strong BFR is dependent on carbohydrates and muscle glycogen.  Those on keto diets need to add carbohydrates before, during and a

Can I do B Strong with "blank" injury?

You can certainly do B Strong with the 3 uninjured extremities and it is good for maintaining fitness.  With the injured extremity, gentle B Strong may be possible as long as the exercises don’t cause pain in the injury site. B Strong is not a medica

Any medical condition where B Strong is contraindicated?

Please refer to the safety page on our website for additional details.

How do I know if I should use more or less pressure in the bands? I currently use 250 in the arm bands and 300 in the leg bands. Is there a benefit of going higher or symptoms if I have gone too high?

The goal of all B Strong sessions is to get a “good”, robust feeling of fatigue from the session.  One has the variables of:. The “job” of the B Strong practitioner is to arrange these 4 variables in combination to get that “good” fatigue signal. So,

Is there a research on B Strong BFR training safe for young athletes around ages 13-16?

There is a study on high school students (14-18 years) and weight training with BFR.  B Strong bands can be used at all ages, but we rarely start before puberty.

Are there any benefits in wearing the bands with a brisk walk?

Yes, B Strong bands can be used anywhere, at any time, by anyone, for any activity.  Indoors/outdoors, winter/summer, land/water, etc. Both arm and leg bands can be used during walking.  Make sure you are well hydrated and nourished and following the

Can B Strong BFR help with hyperactivity?

No

Surgery & Recovery Usage

Sorry, this is not something we're able to advise on. Your surgeon or your physical therapists should give you specific directions post-op.  However, there is nothing wrong with doing B Strong training on those extremities that were unrelated to the

Skin Discoloration

When people perform a B Strong workout, blood is pooled in the extremity and some goes close to the skin’s surface, which can change the color of the skin.  Depending on the skin tone of the person, the resulting color can range from pink to red to o

I’m 50yrs old and want to know how to use the B Strong BFR for cardio safely?

B Strong BFR training is safe for all ages and all activities, including those people with a history of cardiac disease.  However, before starting any exercise program, please make sure that you check with your physician.

Can I use B Strong if I have suffered a stroke?

Regular exercise is an important component of rehabilitation for patients with stokes (CVA’s). B Strong BFR is ideally suited to produce significant gains in function in patients who have had a stroke. This can have a dramatic effect on the individua

What % of arterial flow restriction are B Strong BFR able to obtain?

The only important safety point is that B Strong BFR BandsTM can not occlude arterial inflow in an extremity up to the limit of the hand pump (500 mmHg) when instructions and guidelines are followed. All complications, or negative side effects with B

Is B Strong BFR training a form of occlusion training?

No, B STRONG BFR Training does not, if safety rules are followed, totally occlude blood flow in a limb (safety rule #2), while that is what occlusion training seeks.

Occlusion vs. Blood Flow Restriction Training

See the safety video where we compare occlusion training with a blood pressure cuff and the B Strong Training System. The difference between occlusion training and BFR Training is that in the former case, the limb’s blood flow is occluded and in the

What is occlusion training and why is it dangerous?

Occlusion training involves completely stopping blood flow into an extremity for substantial periods of time. It can damage tissue distal (below) to the occlusion. Completely occluding a limb for a substantial period of time increases the risk of blo

Rhabdomyolysis

There is a very low risk of Rhabdomyolysis. Rhabdomyolysis does not occur when individuals follow the safety rules of the B Strong BFR Training System. A constellation of factors must occur together to get rhabdomyolysis. Rhabdomyolysis is associated

When should you not engage in BFR training?

General Anesthetic - You should wait 3 days after a general anesthetic before resuming B Strong Training sessions.Pregnancy - Out of an abundance of caution, we do not recommend pregnant women to start B Strong Training sessions during their pregnanc

Can B Strong training system be used even after an injury?

Yes! B Strong is uniquely suited to allow continued strength training while not disturbing the healing injury. If, for example, one tears their right ACL, they may continue B Strong BFR Training on the other three extremities as normal. In addition,

Varicose Veins

B Strong BFR Training System Bands and protocols do not increase the risk of varicosities, if anything, they work toward reducing varicosities. Varicose veins are the result of incompetent valves in the veins linking the deep to superficial venous sy

What are the risks or side effects?

As long as the safety rules and cautions are followed, and B Strong equipment and guidance app are used and followed, there are no risks associated with B Strong BFR Training beyond those associated with any exercise. Please consult your with your ph

Who should not do this?

As with any exercise program, all practioners of B Strong BFR Training should use common sense in deciding if they should proceed with a session. They should consult their physician if they have any questions about their particular circumstances. The

Can doing B Strong training lead to pulmonary embolisms or blood clots?

Not if the 5 safety rules are followed.  If blood in deep veins is brought to a standstill for a prolonged period of time, the blood can begin to form clots.  If this happens and the clots move into the lungs, they will cause what is called a pulmona

What are the effects of B Strong training on the heart?

Short Term. During a B Strong training session, heart rate and blood pressure are somewhat higher than they would otherwise be for the given exercise. Long Term. BFR training has many positive effects on the cardiovascular system, including the heart

What are the side effects of using B Strong training system?

We are unaware of any contraindications, negative side effects or complications from using the B STRONG Training System when performed following the 5 Safety Rules:. Of course, if there is an ongoing medical emergency (e.g. heart attack, hypertensive

How does BFR compare to oxygen deprivation strategies and training in Hypoxia?

Some have asked if oxygen deprivation masks work the same way that BFR belts do in producing hypoxia and then, if so, is that what is producing performance improvements from both technologies.  The quick answer is that “No, they work in completely di

If there are no micro tears in the muscles with the B Strong, what does the increase in lactic acid and subsequent secretion of growth hormones do?

Micro tears or muscle fiber damage are not necessary to stimulate lactate production or Growth Hormone secretion. It is the disturbance of homeostasis that raises lactate concentrations and stimulates secretion of Growth Hormone and they, in turn, st

Lactic Acid

Does lactic acid have a role in the B Strong BFR training system?. Yes. Lactic acid is one of many factors that helps stimulate adaptation and growth of muscle. However, it is not a goal, in and of itself, to get high lactate levels in blood with the

Tendon and Joint Strengthening

Recently, a new study has been published showing increase in stiffness and a slight increase in cross sectional area (CSA) of human Achilles tendon in response to a BFR training program.  These new data confirm what we expected.  That is we know we c

What is the effect on the tendon strength?

Specifically, the answer to this direct question is not known yet. However, it depends on what the stimulus for tendon adaptation is and that is not known for sure, either. If the trigger is large absolute force loads across the tendon, then BFR will

Does blood flow restriction training really work?

Multiple research labs in independent studies have reported that BFR training produces strength gains similar to maximal resistance training (weights).  It is important to note that not all BFR techniques and products are created equal.  B Strong pro

What is the relationship between my blood pressure and the B Strong training system pressure?

When one uses a blood pressure cuff, or surgical tourniquet, and if it is applied at a pressure higher than systolic blood pressure, occlusion can occur. So with those systems, there is an important relationship between cuff pressure and blood pressu
