Who should not do this?Updated a year ago

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. There are very few situations where people should not use the B Strong BFR System^TM.

1. People should wait one week after major surgical procedures before starting or resuming B Strong BFR Training. This caution is primarily given to give time for asymptomatic, untreated deep venous thromboses to be identified and treated. 
2. People should not put (B)STRONG Belts directly on healing incisions or wounds. If, for example, there is an incision on the outside of the thigh (as in a total hip replacement) where the leg belt would go, the individual should avoid placing a leg belt directly on the incision, but they can enjoy BFR training on the other three extremities. 
3. Women, if they know they are pregnant, should wait until after delivery before starting (B)STRONG BFR Training. Note: as with any exercise, if they have been BFR training prior to discovering they are pregnant, no need to stop. They may do BFR training, on the easy side, until they feel uncomfortable doing (B)STRONG BFR Training (usually in the last trimester). they should consult their obstetrician if they have any questions or are a high risk pregnancy. 
4. If a person’s limb girth in the appropriate belt location is less than 19 cm (7.5”), that limb (usually an arm) is too small for our smallest belts. We have only seen this situation with children weighing less than 60 lbs. They may enjoy (B)STRONG BFR Training on their legs only. 
5. If a person’s limb girth in the appropriate belt location is greater than 95 cm (37.5”), that limb (usually a leg) is too large for our largest belt. We have not run into this situation yet, but those individuals may enjoy (B)STRONG BFR Training on their arms only. 
6. If someone is having a medical emergency of any sort, he/she should stop BFR training, call 911 and/or go to the emergency room and seek care. 
7. People should not operate a vehicle while doing BFR training. However, it is fine for passengers to do so, as long as they do not distract the driver. 
8. If a person has a condition that has produced lymphedema, he/she should avoid BFR on that extremity and they should consult their physician before proceeding. 
9. If a person has iatrogenic vascular access on an extremity (e.g. hemodialysis patients), he/she should avoid BFR on that extremity and they should consult their physician. 
10. If a person has untreated deep venous thromboses, he/she should not do BFR training until they are treated. 
11. If a person is in hypertensive crisis or has untreated hypertension, he/she should seek medical attention and then when their hypertension is controlled, proceed with BFR training, after they have consulted their physician.
