The band, wrap, or cuff of the limb creates compression, occluding the veins while allowing normal flow through the arteries. Vein occlusion slows the return of low-oxygen, high-lactate blood flow from the arms or legs. Blood flow restriction training is a technique that can be used to perform exercises with a reduced amount of blood flow to the arm or leg. This is often done with a cuff or strap that fits tightly around the limb to reduce, but not completely occlude, blood flow.
The benefit of blood flow restriction training is that it allows the person to exercise with less intensity, but still have the benefits of high intensity training. Occlusion training involves disrupting blood flow to the limbs at work. A tourniquet or bracelet is placed around the limb and the pressure increases as the workout begins. Similar to heavy weight lifting, bfr training allows your body to experience periods of rapid blood circulation in which oxygen flows throughout the circulatory system.
This should be more than enough for most people, but I recommend that you measure your arms and legs before buying bfr bands to make sure they fit you well. Blood flow restriction training, also called occlusion training, involves placing an inflatable cuff on the limb you are exercising. During BFR training, the tight-fitting band or strap on the affected limb restricts blood flow in (which carries oxygen) and out (which carries lactic acid and other wastes from muscle activity) below the compression level. This type of restraint training is good for people with injuries or physical limitations to help build muscle.
Putting these bands tight enough on my legs was also more difficult than with the other bands I tried. The BFR BANDS occlusion training bands are only available as a set of two, making them a practical option as you can wear them on your arms or legs. Many BFR bands have loops to secure the extra material, so even if your bands are too long, you can use the loop to keep the extra fabric out of the way. If everything you've heard about BFR training has piqued your interest and you're eager to learn more, consider taking the Smart Cuffs Level 1 Blood Flow Restriction Certification Course.
According to a study published in the European Journal of Applied Physiology, participants who underwent a combination of high-intensity resistance training and blood flow restriction training showed a 15.3% increase in their 1RM bench press. Rather than having to estimate the amount of pressure you're using, these BFR cuffs measure your blood pressure to determine how much pressure you need. Blood flow restriction (or BFR) training involves placing bands around the upper arms or legs to partially restrict blood flow to the extremities. And even if you are a real enthusiast, “no pain or gain,” studies on medical tourniquets have shown that you would have to completely cut off blood flow to a limb for about two hours to cause damage to nerves and muscles.
However, the bands have a rubber logo that is difficult to get through the buckle of the arm bands.
