Newest lifestyle trend: salons that are combined with fitness centers (how has the Observer missed this one?). The salon, JF Gymnastique in Manhattan, is run by a Frederic Fekkai alumnus; the little fitness center-only three people at a time, please- also has "a team of chiropractors, acupuncturists, soft-tissue specialists, massage therapists, and nutritional counselors offer a range of à la carte services to complement clients' workout routines." As well as "a private locker room, replete with Frette towels and bath and body products from Phyto and Roger & Gallet." Upcoming lifestyle trend: the least hardcore gyms ever. [NYS]
