was thinking of buying a floor to ceiling ball but have afew queries, how do you attach the ball to the floor? i have a beam were it can attach to the ceiling but the floor is solid? any help appreciated.
You can buy a hook on a plate that sits on the floor and you put weight plates on it to keep it in place, but I would recommend using a dynabolt to attach it directly to the floor, as the weight plates can still move about.
