Lincoln Square Athletic Club When it comes to the Chicago Athletic Clubs chain, you can’t have too much of a good thing. The 21,00-square-foot Lincoln Square outpost follows the same formula as the other four upscale neighborhood gyms in the family: ample space for cardio and strength training equipment, creative classes (see Gagaroebics), a spa and, beginning this fall, kiddie day care. Knowing how quick gyms are to give and take away deals (enrollment fee-free!), you’d best sign up now to take advantage of new-member specials. 4662 N Lincoln Ave (773-529-2023, chicagoathleticclubs.com).
