The bands are designed to gently slow blood flow out of the working muscle through the veins, while arteries continue to deliver fresh blood normally. It does not cut off blood supply. When worn correctly (snug, but not painful) it is widely used in athletics and physiotherapy.

By trapping blood in the muscle, the bands create "metabolic stress," which signals your body to grow just as it would with heavy mechanical tension. This allows you to achieve a heavy-training effect without placing heavy loads on your joints.

They should be placed high on your upper arms (near the shoulder); they should never be placed on the forearm, elbow, or calf. They should be tightened to a snug pressure (roughly a 7 out of 10) but never tight enough to cause sharp pain, numbness, or tingling.

These bands are suitable for anyone looking to build muscle without lifting heavy, including people short on time, those training around joint issues or injuries, and lifters experiencing plateaus. If you have a heart condition, blood pressure issues, clotting disorders, or are pregnant, you should consult a doctor first.

You will feel an immediate "pump" or tight, full feeling during your first session. Visible changes in muscle size and endurance typically develop over a few weeks of consistent use, with two to three short sessions per week using light weights.
