Safety first: 

 

Using the cuffs tighter than recommended = risk of nerve/vascular issues. This also counts for using the cuffs for longer than advised. Use BFR cuffs only if you’re in good health and free from conditions like heart problems, high blood pressure, circulation issues and do not use if pregnant. Do not use if you are injured, unless your physio/medical professional gives you permission.  Use them as instructed, snug fit but never painful and never wear them longer than recommended. Stop and unstrap immediately if you feel dizzy, numb, or unusually uncomfortable. For best results and safety, start with guidance from a qualified trainer or healthcare professional. Please consult a physician before using BFR cuffs, especially if you have any medical conditions or concerns about your health. 

Use of this product is entirely at your own risk.
