Blue Sugar Salon & Spa at Ten X Club, Natick

24-hour access. Group fitness classes. Personal trainers. Some of Ten X Club's amenities and services might seem familiar, but it's the combination of these benefits that makes the gym special. Plus, it's a workout space dedicated solely to women and their fitness needs. Members can stop by during regular business hours to meet with a personal trainer, or attend evening and morning yoga, Zumba, and strength training classes. However, they can also drop in any time and swipe their 24-hour access key card—one of the many perks of membership—to gain access to the equipment at any time.
