I had to Google what they are called! But basically fat under the crescent of your bum cheeks.
I got these in my first pregnancy, despite always being a healthy weight. It's not genetic as nobody else in my family has them. Post pregnancy I got down to BMI 20 to try to get rid of them but they did not budge! I couldn't lose more weight as I had very low body fat at that point and looked quite gaunt (I have a broad frame so this is a low BMI for me).
I've done a lot of work on my glutes and they are stronger but the flipping banana rolls are still there.
Any other ideas? Am I stuck sitting on my bananas for life?
