ISTANBUL — Ladies-only gyms have become popular in Turkey over the past few years. B-fit is a franchise that began with the initiative of six women to start a women-only gym in 2006. Now with 220 branches in 48 cities, B-fit has approximately 180,000 customers who are dedicated to their workout. Demet Sarıkaya from the Balmumcu branch said the reason why a women-only gym is so popular is because it allows women to work out in a safe environment without feeling uncomfortable. Offering such activities as Fit popo, Zumba, Pilates, yoga and dance, B-fit opens its doors to women only.
