No Gym? No Problem. Try a Pop Up Fitness Class.

These limited outdoor sessions are taking Boston by storm.

While you may have attended a pop-up shop selling food or clothes, have you attended a pop-up workout? No longer do you need to pay rent or even have a regular schedule to dish out fitness commands. In New England, we love to take advantage of our warm weather months by moving as much of our lives outdoors including our workouts. Why go to the gym when you can take it to the Charles?

Pop up workouts started in New York City thanks to a new company called KiwiSweat, which operates online and hosts workouts in different non-gym environments throughout the week. Think outdoor spin classes on the Hudson or African Dance fused with Kickboxing in Chelsea Market. While KiwiSweat is not yet hosting classes in Boston, there are other options for unconventional locations.

The Esplanade Association is offering free fitness classes starting July 9 and continuing through August 31. On Monday, join up for a 3-, 5- or 7-mile community run at 6:30 p.m. On Tuesdays, enjoy Zumba; on Wednesdays, try yoga; on Thursdays, go for bootcamp; and finish it out on Fridays with a gentle flow yoga. Zumba, gentle flow yoga, and community runs meet at the Hatchshell, while Zumba and bootcamp are located at Fielder Field. All start at 6 p.m. and last for an hour unless noted otherwise above.

If weekends are more your speed, try FitCode Boston, which offers a variety of classes taught by some of the city’s most beloved group exercise instructors at Titus Sparrow Park in the South End off West Newton Street. On July 15, get your zen on with Sasha Yakhkind for just $10.

Lastly, don’t miss out on the only free you’ll ever get at the swanky Liberty Hotel. Free classes courtesy of Equinox are available to guests and non-hotel guests and start at 10 a.m. on Saturdays. This Saturday, catch Pilates Fusion with Swan Lyons. Non-guests should bring a mat.
