pull-up n.

c. 1300 (mid-13c. in surnames), "to move or try to move forcibly by pulling, to drag forcibly or with effort," from Old English pullian "to pluck off (wool), to draw out," a word of unknown origin, perhaps related to Low German pulen "remove the shell or husk," Frisian pûlje "to shell, husk," Middle Dutch polen "to peel, strip," Icelandic pula "work hard." Related: Pulled; pulling.

From early 14c. as "to pick, pull off, gather by hand" (fruit, flowers, berries, leaves, petals, etc.); mid-14c. as "to extract, uproot" (of teeth, weeds, etc.).

Sense of "to draw (to oneself), attract" is from c. 1400; sense of "to pluck at with the fingers" is from c. 1400; meaning "tear to pieces" is mid-15c. By late 16c. it had replaced draw (v.) in these senses. From mid-14c. as "to deprive (someone of something)."

Thornton's "American Glossary" (1912) has pull (n.)
