No cash for a gym membership? Get fit for FREE. Here are a couple of ideas. Barter or volunteer: If you can’t afford to pay for fitness classes or yoga, trade or work at your favorite studio in exchange for classes. Some yoga studios offer a program in which you man the front desk, clean the studio or do other necessary tasks in exchange. If you don’t have a lot of time to commit, ask if you can simply clean and tidy up the studio before and after class to receive that class for free. If you have other skills like website design, offer these services to your favorite studio on the house (or on the cheap) in trade for free classes. It never hurts to ask. Get outdoors: Now that summer is here, substitute these awesome workout classes for a good old-fashioned run outside. Keep tabs on your progress, elevation, speed and more by downloading the Map My Run app for your smartphone. It uses your phone’s GPS to track every step for accurate results to keep you motivated.
