Milwaukee's East Side Business Improvement District is holding a fitness crawl — no, not a new type of workout involving crawl — Saturday starting at 11:30 a.m. at Adventure Rock, 2220 N. Commerce St. Like a bar crawl, participants go from stop to stop (walking or running), but instead of a drink, you're trying a new exercise at each spot. The six other stops include Shred415, Crossfit 414, East Side Pilates, East Side Family Chiropractic, Urban Om and Yoga Six. The crawl winds down at Good City Brewing, 2108 N. Farwell Ave. The fitness crawl costs $40.
