Cleveland Browns star Malik McDowell got in a very boring and uneventful workout at a Florida gym shortly before he was arrested for being completely naked in public.
TMZ Sports obtained surveillance videos recorded Monday at the gym in Deerfield Beach, FL ... where the 6'6", 290 lb. D-lineman is seen walking around, hugging friends and all in all ... just acting completely normal.
People close to McDowell tell us ... after the gym, he walked next door to the hotel where he was staying, and took a shower -- and we're told he never got dressed after that.
