TANGERANG, Indonesia — Potbellied police in Indonesia’s capital have been ordered to exercise, exchanging their uniforms twice a week for sweats and sneakers as they line up for aerobics and pushups to try to drop a few pounds.

Jakarta police spokesman Col. Rikwanto says anyone in excess of 220 pounds must follow the weight-loss program started because of the growing number of overweight officers and the perception that they are unable to provide public protection.

He says stress, sedentary lifestyles, and junk food have made the capital’s police officers put on unwanted weight. Registration began recently, and anyone deemed too fat will be required to exercise at least twice a week.

No one will be punished for not losing weight, but officers are not allowed to skip exercise sessions.
