Aspects provide a punching bag formed by a body panel with a first edge that forms a first closed end, and a second edge distal to the first that defines a second opened end of an interior enclosure of the punching bag that is bounded within interior surface sidewalls of the body panel between the first closed end and the second opened end. The first closed end traps air within the interior enclosure that is configured to interact via the second opened end with ambient air within an outer area surrounding the body panel, to thereby slow motion of the punching bag as it is conveyed through the ambient air in response to forces imparted to the bag body panel by a user.
