Oklahoma City Fire Department firefighters were caught getting in their morning workout on April 24 with some interesting items.

In a video posted to the department’s official Facebook page, the firefighters can be seen working out with kettle bells, weight balls and a CPR dummy. A fireman is seen pumping the dummy up and down over his head.

Another is seen flipping a tire while others do step-ups and rope exercises in the firehouse, proving a workout can be improvised from almost anything. As of writing, the video has more than 2,000 views on Facebook. Credit: Oklahoma City Fire Department via Storyful
