First Lady Michelle Obama was challenged by her husband, President Obama, to show him five ways she stays in shape. She accepted his challenge, but I'm sure he didn't expect for her response to be this fierce. Maybe he did, since she always brings it with every issue she's worked with including supporting military families, helping children lead healthier lives, and encouraging all young people to fulfill their boundless promise. Our stylish, and very fit, FLOTUS used her national platform Let's Move to show Mr. President just how she moves. Check out her call to action, and all her fitness moves in the #GIMMEFIVE FLOTUS Style video.
