“Fitness sharing” is the latest startup buzzword around these parts, with several apps launching this summer offering access to the city’s boutique fitness studios. Fitness sharing aims to eradicate the need for multiple costly memberships to various studios and allow fitness enthusiasts to dip in and try classes at different places all over town. Newly launched this week is Singapore-based Guavapass, which allows members to attend fitness classes at studios such as Coastal Fitness, Apefit, Torq Cycle and Versus Performance, to name just a few – all for $899 a month.
