President Obama decided to get a workout in while on a trip to Poland. Someone captured The President on an elliptical and doing various exercises with free weights. 

The POTUS routinely works out at hotel gyms during his travels. Hotel guests are permitted to remain in the gym during his workouts, however anyone staying in a hotel where Obama is spending the night must pass through a metal detector. The Secret Service does not consider the Polish hotel incident a security violation.

A Secret Service spokesman said the gym visit, which was not on Obama's official schedule, was no different than the president's surprise attendance at a restaurant where other diners can engage him and take pictures.
