There were plenty of backward, forward and sideways flips happening at Boys and Girls Gym in Springvale, Whanganui on Monday.
Supervisor Jess Vigenser said bookings for school holiday programmes are on the increase and there were 36 children aged from 5 to 13 attending yesterday.
"We are expecting 40 tomorrow," she said.
"The enrolments seem to be growing each holidays and they are sky-rocketing at the moment."
After a morning of circuit training in the gym yesterday, children made mini pizzas before heading for a swim at the Splash Centre.
The fun will continue throughout this week and next with trips to Bushy Park and Kowhai Park as well as baking, swimming and more gymnastics.
