A free Pilates demonstration will be given at 8 a.m. on Saturday, May 6, at the Homewood-Flossmoor Park District’s Racquet and Fitness Club, 2920 W. 183rd St., Homewood. Instructor Liz Camacho said the session is meant to introduce residents to Pilates, a form of exercise that provides intentional, precise movement and stretches the core muscles as participants use several pieces of exercise apparatus. The program is open to all ages interested in developing strength, flexibility and improved posture. Pilates is also a good exercise regime for people who have completed physical rehabilitation sessions, she said . . .
