A leaked video surfaced Wednesday of President Obama lifting weights at a hotel in Warsaw. It's no surprise that Obama values physical fitness and it wasn't the first time we've seen presidents engaged in vigorous activity.

He's joined by Speaker of the House Fredrick Gillett.
President Ronald Reagan shared his presidential fitness routine in a 1983 Parade magazine cover story.
