FlexDropin goes live here on September 30. It does one thing: you book and pay for a single gym class, with no membership and no credit packs.

The idea came from our founder Maria, who trains across several disciplines and could never find one gym that covered them all. I hit the same wall from the other side: I travel for work, and getting into a gym for one session is usually a phone call, if it's possible at all.

Before launch day I'd like to hear from people who train: what actually stopped you the last time you wanted to work out somewhere you don't have a membership? Price, not knowing if drop-in was even allowed, or just not wanting to ask?
