For me these serve 2 purposes. 1. helping with muscle recovery after olympic lifting and 2. helping tone up those stubborn areas of cellulite. So far its to soon to see any real difference with the cellulite but i use this every night after i shower on my legs and i dont wake up as sore as i usually do after a night of heavy lifting. It is a bit painful so let me warn you there but im not sure if its because im already sore or if thats just how it is. but its worth it for me. It leaves your skin reddish but that goes away after a few minutes. im really excited to see what it does for the cellulite i have on my outter thights.
