Gymstick Pro Exercise resistance bands are low-protein and low-powder, so they do not cause the discomfort of a traditional tape due to the mess caused by the powder, and you don’t have to worry about latex allergies either. (Note: powder is used because of the stickiness of the latex) Latex allergy has been resolved in two ways: first, most of the proteins in the latex are removed from the Gymstick Exercise resistance rubber bands. Second, the Gymstick Exercise Resistance Tape is washed to remove excess powder, reducing the possibility of the powder acting as a protein carrier to the wearer’s skin in skin contact. 6 different resistance options available.
