Balance Chestnut Hill

At the beleaguered behest of their devoted clientele (among them, local socialites, CHA’s varsity football team, Springside’s track-and-fielders, and Jimmy Rollins), this personal-training power trio — Aaron Sistrunk, Amy Carolla and Johari Smith (who also happens to be Rollins’s fiancée) — have finally opened a place of their own. It’s just big enough to host group classes, but we’re signing on for Sistrunk’s intense 30-minute sessions, one-on-one Pilates with Carolla, and speed-conditioning with Smith.
