Gym slots on a half-hour grid

If your building has a gym, it is full at two moments of the day and empty the rest of the time. In Doory, members reserve a slot on a half-hour grid, within the capacity the building can handle.

Why a gym without reservations doesn't work

A room with six machines intended for a building with three hundred people is too full at 08:00 and at 17:30 and empty in between. Without reservations, someone comes downstairs, sees it is full, and goes back up. After three times they stop using the gym, and then a facility you charge rent for is an empty room.

How reserving works

You set the opening hours and capacity per building: how many people may be in at the same time. Doory divides the day into half-hour blocks and members reserve a slot in the portal or in the app. If a slot is full, they see that and choose another time.

A half-hour grid fits how a gym in an office building is used. People come before work, at lunch or at the end of the day, and are rarely there for longer than an hour. A finer grid only creates admin, a coarser grid wastes capacity.

What it shows you

Occupancy per part of the day. That almost always reveals the same pattern: two peaks and a lot of empty hours. You can do something with those figures, for example an offer for lunchtime, or the decision that a second treadmill is more useful than a second weight bench.

If you see that the peaks are structurally full and members drop out, that is a well-founded case for expansion, or for setting up the room differently.

Why this belongs with access

Because the gym is often behind a door that isn't open to everyone. Reservations and access go hand in hand: a member with a slot can get in, and access follows their member status. If they leave, gym access ends too.

What you decide yourself

The capacity and how far ahead people can reserve. Too far ahead leads to slots that are claimed and not used. Two to seven days works best in practice.
