I use it daily, gradually adding new exercises to improve my core. I bought it because of years of lower-leg inflammation. I used to take prescription water pills daily, but since starting to use the board, I no longer need them. Each day, the leg inflammation decreases. I'm hopeful it will continue to improve with continued use. After skipping one night, I noticed a difference during the night, and my legs felt heavy! I highly recommend this board. Currently, I'm happy to experience less leg weight.
