This isn't just a product of lower extremity but I can do few of the upper extremity exercises too. The main reason I really liked it is because the fabric absorbs the sweat and it's not too tight that it restricts the blood flow. I share my band with my thick thigh friend and even she feels comfortable using it. The product comes with 3 variant bands: Light, Medium and Heavy according to need. It looks durable and let's see how long it survives as I am using it daily. Nothing I can think of disliking the band as of now.
I recommend it!
