I used it all the time at the gym to do planks, side planks and stability training (weight lifting while standing on it). As it is so useful, I bought one for my husband to use at home. Once having it at home, I discovered another great use for the pad. I use it as a seat cushion when I meditate. Because it is firm, it doesn't sink in like pillows and gives my hip great support. I can sit longer and feel less discomfort on it than sitting on the floor.
