President is staying at the hotel this year for the ongoing Nato summit

Secret service said at the time it did not constitute a breach of security

Barack Obama was first snapped in the same gym in June 2014

Wore pink headphones as he went from the treadmill to the spin bike

Barack Obama was spotted in the middle of a workout once again - in the same Polish hotel gym where he was first spotted lifting weights two years ago sparking a security scandal.

New photos show the president going from the treadmill to the spin bike Friday at the Marriott hotel in Warsaw, dressed in black with pink headphones in his ears.

They look like the reconstitution of pictures that first ran in a Polish tabloid two years ago: Obama in the same gym, lifting dumbbells and doing lunges among other hotel guests.

Security concerns emerged at the time, but the secret service said the president's workout did not constitute a breach of safety.

Indeed, a security team of at least five men escorted Obama to the gym before his newest sweat session.

The president traveled to Warsaw for the Nato summit on Friday and Saturday. He stayed at the same hotel two years to celebrate the 25th anniversary of Polish Freedom Day, which originally marked the country's first post-Communist elections in 1989.

Two years later, Obama wore a black t-shirt with short sleeves and matching track pants as he returned to the gym.

The president, who told Men's Health in 2008 he worked out for 45 minutes, six days a week, seemed to select a program on a treadmill and spent part of his session on a spin bike.

And just like last time, at least one other guest carries his own session mere feet away from him.

The secret service told CNN after the first images came out that Obama hadn't been in any danger when the curious photographer snapped him mid-workout.

Security personnel had screened everyone coming in and out of the hotel, ruling out the possibility of any dangerous item, a member of the agency said.

The secret service doesn't usually ask other guests to leave the premises when the president visits a hotel gym, and they do not ask them to refrain from taking pictures of him.

Obama's staff knew someone was snapping photos of him that first time, but no one intervened to make it stop.
