A brilliant concept Although expensive I’m pleased this item. I thought I could get the same effect from using a yoga strap, but in fact, having the whole forearm in the slot activates completely different muscles. It is very adaptable for many different exercises and for different sized people because there are multiple openings. It is well stitched so feel sturdy and made to last. A good addition to my exercise equipment, and I’m very satisfied with other Sissel items that I have purchased.
