Junior Gym and Fitness Classes

What is Junior Gym?

Junior gym is a time where children aged between 11 and 17 can use the gym, to help them begin or maintain a health lifestyle from an early age. A fitness instructor will be present to ensure that safe practices are being carried out.

All juniors are required to attend an induction with a Fitness Instructor before their first session. 

Junior Gym Sessions at Chelsea Sports Centre are 4pm-6pm Monday-Friday, 2pm-4pm at weekends and 10am-12pm during school holidays.
