Do you want a callipygian figure? Try adding squats and lunges to your exercise routine. Believe it or not, callipygian means "having a shapely rear end."
Callipygian comes from the combination of the two ancient Greek words for "beauty" and "buttocks" and was famously used to name a statue of the Greek Goddess of Love, the so-called Aphrodite Kallipygos, who raises her robe to reveal her backside. If you're interested in learning more about Greco-Roman beauty standards, you can view a Roman copy of the statue at the National Archaeological Museum in Naples.
