i.d. gym

This Lincoln Park space is no stranger to fitness equipment. The address used to belong to a Crunch gym. Before that, it was Gorilla Sports, and in the late 1980s, it was Jamnastics. i.d. focuses on group classes (ranging from boxing to boto camp), but it also has the requisite strength and cardio machines. You can also do CrossFit, take kettlebell classes with one of the best kettlebell trainers in the city, or try Fly Yoga, a unique form of aerial yoga.
