✨ Ready for the next step after Kindergym?

We’re excited to introduce Kinder Rec at Onyx Mosman for Term 4! 🤸‍♀️

Designed for 4–5 year olds who haven’t started school yet, Kinder Rec is a great next step for little gymnasts who are ready to build on their Kindergym experience and start developing their gymnastics skills in a smaller group.

From cartwheels and handstands to jumping, balancing, rolls and strength, they’ll build the foundations they need while growing their confidence and independence.

And with daytime classes, it’s an easy way to fit gymnastics into the week before school starts — without adding another afternoon or weekend commitment.

📍 Mosman
🗓️ Monday 11:30am–12:30pm
🗓️ Thursday 9:15am–10:15am

📅 Term bookings

Term 4 bookings are now open!

Head to the link in our bio to book your child’s place. 🤍

Snack Break 🍪 vs Extra Training 🤸‍♀️

The gymnasts get to choose their option… but somehow the coach always ends up with the snack while they get extra drills. 💀😂

Fair? I think so. 😌😂
