As far as I am concerned, all gyms need to have lockers available for their clients. I realize that not all clients use gym lockers, but many of us do. I like to use my gym locker for my extra change of clothes. I work out in the morning before I go to work. After my workout, I shower in the gym’s facilities and change into my work clothes. This works out very well for me. However, if the gym where I have a membership did not have lockers, I could not do this. It would end up being a real inconvenience for me.
