Travelers looking for a workout could turn to an app that directs them to the nearest gym. 

These apps could also allow the customer to purchase a one-day pass to a nearby gym straight from their phones, Reuters reported. 

"Most hotel gyms are just a small row of treadmills, and maybe a half-complete weight rack. For anyone serious about working out, it's usually not enough," Kevin Bracken, chief executive officer of the new app Gymsurfing based in San Francisco, California, told Reuters. 

Gymsurfing will allow users to see nearby gyms as well as the cost of a one-day pass and any deals they may be offering. 

"You see a variety of gyms and amenities they offer, such as the type of equipment they have, and whether they have pools, saunas, or spas," Bracken said.

Day passes will most likely cost between $5 and $20 and will be available at a wide variety of establishments. 

"Our goal is make it so that as soon as you land in whatever city you're going to, you can find a place to work out," Bracken said. 

Similar smartphone apps include OmFinder which looks for nearby yoga classes and GymPoints which allows users to browse nearby gyms and search for local drop-in classes such as pilates and martial arts. 

"In the age of the carry-on bag, working out while on the road has kind of fallen to the wayside because there's not enough room for their clothes, particularly their shoes," Chris McGinnis, editor of the website TravelSkills, told Reuters. 

"Most hotels have gyms, but it may be a dank basement gym with no windows to the outside, or people might want the social experience of going to a gym, so in those cases an app might come in handy," he said.
