Now I dont work in the law enforcement industry but I do work in an industry that has supposed fitness requirements although they arent enforced.

For us, the union told them “If they have to maintain a weight of X to remain employed. You have to pay them to hit the gym on company time or pay their gym fees and an allowance.” So the company filed that away under “fuck that”. Now if you get too fat for the equipment they just move you to a different duty, often one with a shitload of walking around.
