Calling all gym members with children!
Would you like to bring along your child to train with you in the gym? If so then Adult & Junior Gym is perfect for you!
The junior will need to book rather than the adult and will be required to undertake an induction before being able to attend. The sessions will be chargeable for the junior (unless a pre-paid member) and the adult will either need to be a pre-paid member of book & pay for a gym session.
Supervision: Please note that the adult/parent must actively supervise the child at all times and takes responsibility for the child's conduct and safe use of machines. Only children between 11-17yrs are permitted in the session, and it is limited to one child per one supervising adult. If an adult is not supervising the child or the child misuses the gym equipment or misbehaves, both parties may be asked to leave.
