3 Fitness Apps for the Busy Gym-Goer

There's nothing worse than finding a group-exercise class you love and then realizing that everyone else loves it too, so it's impossible to snag a spot. Enter these three free class-booking apps: They make finding new fitness studios and signing up for a session a snap. Even if you decide last minute that you'd like to jump into a class, you can easily track down an opening. Download one to your phone and you'll never have to keep hitting refresh to see if you've gotten into a packed class again.

BurnThis

Whether you're in LA, NYC, Chicago, or Miami, you can tap into this app to book classes and connect with friends who share your fitness interests. After creating a profile, browse workouts, sign up in seconds (you can even nab discounted packages on listings marked with a "deal tag" icon), and invite friends to come sweat with you. Each BurnThis listing notes how many spaces are left in the session, so even if you're adding it to your schedule in a hurry, you'll know if there's room for others to join you.

Gymsurfing

Keep up with your exercise routine while you travel with Gymsurfing: It boasts a list of more than 150 gyms and fitness studios across the country, in cities from Spokane, WA, to Charleston, SC. Many of the listings let you pop in for a single workout, for as little as $5. Pick your location and you'll get a barcode to help you check in easily when you arrive.

Beautified

This app launched last year in New York City to help users book last-minute spa and salon appointments and score deals while doing so. Noting the connection between fitness and looking your best, it recently added fitness classes to its lineup‚ including perennial favorites like Barry's Bootcamp and Body by Simone, to help you squeeze in a sweat session anytime. Beautified also has plans for an upcoming expansion to Los Angeles and San Francisco as well.
