JUNIOR GYM RULES

Mandatory inductions – To keep everyone safe, members and non-members can attend our junior gym sessions without an adult. Before, they must take part in one of our induction sessions so they can learn how to use the facilities. Juniors will not be allowed to access the gym without having taken an induction. 

Equipment restrictions – So everyone can work out within their limits, we have some age restrictions on our gym equipment. Junior members between 11 and 15 years can use cardiovascular and fixed resistance machines such as treadmills, chest press machines etc. but only 16 and 17 year olds can use the free weights (only specified weights). Juniors may remove weights up to 10kg from the free weights area but cannot remain in the area.

Adult and junior sessions - Alongside our regular classes and sessions for under 18s, we also run adult and junior gym sessions where you can work out with a child. Like our other gym workouts, these slots give you and a child the chance to boost your fitness in the gym and use a range of equipment. While adults take full responsibility for any children aged 11-17 our instructors are always on hand to help.
