24-Hour Fitness Gym at the Jeffrey and Sons building near Shelly Bay Park on North Shore Road. The gym, which features weights and workout machines, will be open round-the-clock to cater to shift workers and those who want to exercise whenever they feel like breaking a sweat. Mr. Jeffrey said he felt there was a big demand for such a service, as most gyms closed too early for most people, or were not open long enough on the weekends. Customers will access the gym with a swipe card.
