Want to know the key to buying a great BFR cuff?


If you’re reading this you probably already understand the basic premise of blood flow restriction training. We'll assume you know the research and you're ready for a set of badass bands that you can rely on to finish off any upper body workout with a skin-splitting pump. The secret to buying a set of bands you're not going to get frustrated with is flexibility. Your arm isn’t a perfect cylinder - you have the deltoids, the triceps, and the biceps all moving simultaneously in the junction where your wraps should be placed on your upper arm  during each rep as the muscles contract. You want a band that has some flex to it - just enough to move with these contractions. If it’s too rigid, it’s puts unnecessary pressure on your arm during the concentric portion of the movement, when you don’t want additional pressure on that deeper artery - you want blood to be able to freely flow into the extremity. Then during the eccentric portion of the rep that band needs to keep enough pressure on venous return (if it loosens up on you, it defeats the whole purpose and you’re wearing expensive sweatbands on your upper arms for no reason). There's an art and a feel to this style of training as much as there's a science. Having a product that finds that balance between rigidity and flexibility can help you really enjoy cranking out all of that extra volume each week rather than hating it! 


“We’re conducting research on occlusion training at Virginia Tech using Lifting Lab’s bands. These are the most comfortable, easy to use, and the material is top notch. I’ve tried them all."

Frequently Asked Questions

Is Blood Flow Restriction Training Safe?

Despite it's outward appearance, studies actually show that in the general population and even in injured recovering populations of people, blood flow restriction training appears to be relatively safe and beneficial. There are certain conditions where it should be avoided - if you have deep vein thrombosis, high blood pressure, are pregnant, or have extremities with varicose veins. We are not medical doctors and you responsible for speaking with your physician, exercising caution, and using this program and these accessories at your own discretion when implementing BFR training for competitive sports or rehab purposes.

What's your refund policy on the bands?

This is another example of how occlusion training can often be counter-intuitive (right there alongside consistent strength gains even with very light weight). Even though vascluar occlusion of blood flow seems like a clot waiting to happen, a handful of studies have proven it to be a relatively safe training method in terms of hemodynamics. This study showed increases in strength without altering vascular function in healthy participants. In fact, it actually showed that it increased fibrinolytic activity, the breakdown of coagulative products which would typically cause clots. Even though BFR training appears to be perfectly safe, you should always check with your physician before engaging in a new exercise program such as this one.

Do you have any videos that show how to put on the straps?

If you receive a pair of cuffs that doesn't fit or appears to be defective, we'll simply replace them for you. We also offer a 30 day money back gaurantee on the upper and lower body cuffs, so if blood flow restriction training isn't your thing simply get in touch with us and we'll get you taken care of.
