Carrot Gyms was proposed by a classmate of mine at UVA. The concept behind the company is to provide traveling business people with the ability to visit any workout facility in their immediate vicinity.
Many folks on business travel often find themselves overeating at restaurants that are covered by per-diem and do not have adequate facilities to exercise. This leads to a very unhealthy life-style. Instead of only having access to a limited hotel gym, which sometimes doesn't exist, Carrot Gyms provides access to local gyms with a membership.
The application works based of a location-based context service and provides users with ratings and info about available Carrot Gym sponsored facilities.
