President Obama was in Poland today where he gave a speech in front of a crowd of thousands in Warsaw. But earlier in the day, the Prez got busy in the hotel gym where someone was able to sneak a video of him working out -- unbeknownst to him or his Secret Service. In the clip, the president appears to be tired as he yawns, but keeps on with his workout which lasted around 30 minutes.
