Humagen Parks enable parents to exercise while they keep close watch over their children. An audible signal sounding 30 minutes after sign-in will let each User know that his or her time limit is up; this will prevent overexertion as well as open up space for the next person. After this warning sound, the User will not be compensated for any energy produced, but can go to another of the 3 devices after a short rest.
Humagen Parks can be sited deep within cities, allowing easy and quick access to pedestrians who wish to get exercise and get paid for it. Each device in the park will allow for a different set of muscles to be exercised.
