What gyms would let a 12 year old in?

Many if not all branches in the YMCA of San Diego have a family friendly program through which children from 7 – 12 can work out on specific equipment with a parent as their training partner. The families must go through a family orientation, the children wear a special wrist band, and they can only be in specified family friendly areas — and never without their parent. If the child is too small for any apparatus, the child and family are shown alternatives. Teens 13 and up can have a teen orientation and use the entire facility.
