Exercise, what?

KDee • Tried for almost 5 years, with every test and almost every fertility procedure, until I finally started telling the doctors which tests to do. Hoping this rainbow baby makes it and stays!
K, so I've been doing lots of exercises (really just stretches) to get ready for this girly. I've done lots of research, and I keep coming across this stretch. Can anyone actually do it and I'm just way out of shape? I cannot ballance and stay flat footed. There's a belly in the way! Anyone that can do it, what am I doing wrong? I tried spreading my legs further apart, and i still can't balance. I feel silly because it looks so simple!
