I just started doing swim therapy with a group. I didn't realize there were different sizes and weights. One of our exercises requires us to put the dumbbells under our arms. Because these are twice as wide as the ones the other women use, they don't quite fit under my arm pits. I'll be looking for a different size. I think they'll be okay later on when I have gotten used to the weight resistance as well. Right now it's very difficult as a beginner.
