It has been only 2 years since IDEA began tracking the popularity of core conditioning classes versus conventional abdominals classes on our annual Fitness Programs & Equipment Survey. In that short time span, the number of fitness facilities offering core conditioning jumped from 61 percent in 2001 to 72 percent in 2002 (see the October 2002 issue of IDEA Fitness Manager). With the recent proliferation of new core equipment, including items like the Reebok Core Board and the BOSU Balance Trainer, core conditioning is proving as popular as fitness-based yoga and Pilates.
