Other FAQs

Q: Is BFR training safe?

A: YES! A significant amount of research has been done on the safety of blood flow restriction training. For relatively healthy people doing it correctly, a systematic review of 35 different scientific studies on the safety of BFR didn't find a single negative effect! Despite appearances, it does not mess up your veins. In fact, BFR has been shown to improve vein health, decrease arterial stiffness, enhance peripheral blood circulation, lower baseline blood pressure, and improve cardiovascular, endocrine, and bone health. 

With that said, since BFR does increase blood pressure during exercise, and is relatively new, anyone with these pre-existing conditions should avoid BFR or consult with their physician first just to be safe.

-Severe high blood pressure

-History of deep vein thrombosis (DVT)

-Vascular insufficiencies

-Severe varicose veins

-Pregnancy

-Diabetes

-Other cardiovascular disease

-Consult a physician if in doubt

Even if you don’t have any pre-existing conditions, please understand that this is not a medical device and I’m NOT giving medical advice. There may well be dangers that neither I nor anyone else is yet aware of, so still I recommend speaking with your doctor to make sure BFR training is safe for you if you have any concerns. 

Finally, it's not recommended even for healthy individuals to use both arm and both leg cuffs at the same time. Only use a maximum of two cuffs at a time.

Q: How do I know if it’s too tight?

A: If you're following the pressure instructions outlined in the video above, then you shouldn't have to worry about this. However, if you want some general symptomatic guidelines, here they are:

First of all, your limb turning red at higher pressures is NORMAL. That’s a sign it’s working. Even slight tingling is normal, and your muscles will ache. However, if you’re turning purple or numb, or feel any sharp pain, your pressure is probably too high.

Q: Can I use BFR with heavy weight?

A: Yes. There’s no danger in that. But the heavier the weight, the less benefit BFR will add. Some studies suggest that if you’re training with over 70% of your 1 rep max, the added growth benefits from BFR are no longer statistically significant.

Q: Should I take the BFR cuffs off between sets, or leave them on?

A: It doesn’t really matter. Studies show there’s not a significant drop in gains if you take them off or depressurize during short rests. But from a practical standpoint, it can be a hassle to take them on and off that much, and there’s no downside or danger to leaving them on, so I typically leave them on.

Interestingly though, other studies have shown that you can get some small benefit from only putting cuffs on during rest periods, and not during the exercises themselves. So that would imply there is some benefit to having them on during those rests.

Q: Do I need to leave them on for any length of time after my workout’s finished?

A: No. You can take them off as soon as you’re done. Although again, interestingly, some studies have shown that you can get a little benefit by putting BFR cuffs on for a while only after your workout is finished, and not during it. So take that for what it’s worth.

Q: How many sets and reps should I do?

A: Since BFR triggers adaptations at much lower volumes, just 1 or 2 sets to failure per exercise is sufficient. However, there’s nothing wrong or dangerous with more. Typically those sets are in the high rep range, but you fatigue much faster with BFR so you’ll hit failure much earlier than you normally would with those light weight loads.

Q: How long should each session last? E.g., is 1 hour with them on too long?

A: Again, BFR gives you results at lower volumes, so the session should end up being shorter than an equivalent workout without BFR. The workouts in my BFR Series programs are all under 30 minutes. No adverse effects have been seen with longer workouts, but I personally wouldn’t go more than an hour without taking them off.

Q: How often can I do BFR each week?

A: That depends on what splits you’re doing. If you’re working a different muscle group every day, you could use BFR every day. But a good rule of thumb I use with my clients and programs is to only do BFR training on the same muscle group up to twice a week with at least 2 days in between.

Please Consider Giving My BFR Bands

A Review! 🙏

I designed every aspect of these bands myself and wanted to create the absolute best nylon-based BFR product on the market. It took me years and dozens of prototypes to achieve! However, as you no doubt know, regardless of their actual quality and innovation Amazon products live and die by reviews! So if you like the bands and appreciate what I've done with them, I would be extremely grateful if you took a minute to post a review on Amazon!! 🙏🙏

Mahalo my friend! 🤙
