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. And unlike big chians that like to lock you into a year membership, this indie neighborhood fitness facility offers month-to-month plans ($65), as well as 12-pack of passes ($180), each good for one class or workout session.
