Acrobatic describes something that's an amazing physical feat, especially if it involves agility and balance. An acrobatic dance routine might include back flips and handstands.
If you're acrobatic, you're good at gymnastics or physical circus tricks. A border collie might make a particularly acrobatic Frisbee catch, twisting and spinning in the air, and a little boy could perform acrobatic cartwheels across the living room. The adjective comes from acrobat, which in French — acrobate — means "tightrope walker," from a Greek word, akrobates, "rope dancer," related to akrobatos, "going on tip toe" or "climbing up high."
