Michelle Obama Has Serious Jump-Roping Skills

Michelle Obama tweeted a short exercise video this week that gives her the distinction of being the only first lady "to wear a gym tank and stretch pants while pounding her fists together in boxing gloves," notes the Washington Post. In the clip, part of Obama's campaign for fitness, she jumps rope, works a medicine ball, hops on and off a workout bench, lifts weights, and does some kickboxing. (The video tweet was part of her welcome to a high-profile new tweeter.)
