Sylvester Stallone’s underdog franchise had its hits and plenty of misses (does anyone actually remember a single thing about Rocky V?), but one of its successes is its inspiring movie buffs to experience a brief moment of exercise. If you find yourself near the Philadelphia Museum of Art steps, you run up them. Simple as that. There is no way around it. Ideally you will wear a bandanna and play the Rocky theme song (“Gonna Fly Now”) in your head. Second-guessing the location? Orient yourself with the nearby Rocky statue.
