1. Travel Frequency: Once a month
2. Airport Activities: I usually fly direct within Asia so I have maybe at most 3 hours before a flight but often I arrive ~1.5-2 hours before my flight and use the lounge for 40-60 mins.
3. Fitness Preferences: Weights
4. Gym Benefits: If I was traveling alone and had at least a 3 hour window
5. Usage Likelihood: Pricing and scheduling would be a big one. I think this would be probably $30 - $40 at minimum?
6. Concerns: Showering/safety of my belongings (where do I put my carry-on)?

Overall I think it has potential but I also think that the people who could afford this, would have fewer layovers? (I am thinking out loud)

I would be curious to see the size of the Venn diagram of:
1. People who work out
2. People who travel
3. People who can't skip a workout and wait until they get to their destination
- there are more things that come to mind but this Venn diagram would likely be the right balance.

Good luck!
