The girls usually train at Brophy Aerials, which Eve said was the sole Dunedin venue which offered aerial hoop.
The apparatus, also known as a lyra, is used by circus performers for a range of acrobatic moves.
During the school holidays the girls decided to take their gear to the park for extra training.
"We had it taken down in a car today and we set it up," Eve said.
"That was the first time we’ve done it at the park, but we plan on doing it quite often."
