I am a week into my membership at the local Equinox gym, and it added some unexpectedly refreshing structure to my daily routine.
Equinox requires advanced scheduling for both solo workouts and classes, providing me with a solid deadline either to end work and leave for the gym, or a strict bed time (in the case of morning workouts).
Being forced to leave my apartment for an appointment also helps me organize my day, because I cannot allow work to sprawl into the late hours of the evening.
