For those trying to keep their New Year’s resolution to get fit in 2018, a New York gym class has a novel idea: Work out in the nude. Hanson Fitness, a gym chain used by celebrities ranging from Rihanna to Sandra Bullock, is offering naked full body conditioning classes start on Jan. 5 at its Soho location, Business Insider reported. The gym will start with three weekly nude exercise classes, one for each of the sexes, and one mixed class. For those who want a more intimate nude exercise experience, there are private sessions available. “These naked personal training sessions are all about creating a ‘new (‘nu-de’) you’, as guests burn the calories whilst nude,” according to the gym’s Facebook event page. So, what exactly are the benefits of working out in the buff? According to the gym, working out without clothes allows the skin to breathe, and “complete body awareness so you can see if you’re cheating on your exercise routines.” “The class is designed to be a total body workout that uses your body weight as resistant to work the glutes, butt, legs and core – making you look and feel good naked,” the gym said on its Facebook page. Still not convinced? According to the gym’s disclaimer, “nude underwear” can be worn during the workout sessions.
