To provide additional proof that one can be impressive without being "huge" here is the famous Brooklyn strongman Abe Boshes. Boshes stood 5'3" at a bodyweight of around 150 pounds and was very well-known for his shoulder development (which was obviously a big contributor to his stature.) Boshes did quite a bit of training with chest expanders.
Boshes could bent-press around 220 lbs for a single and a 100 lb. dumbbell 18 times in succession. In the early 1900's, he won a contest put on by Bernarr MacFadden and the fame from doing so allowed him to travel the country on the Vaudeville circuit. Like many strongmen of the time he also did some wrestling.
