CAC Youth Programs

  • Easy access to work, classes, treadmills, free weights, women's gym was a plus.

  • Great great gym especially if you work in Kendall Square. They offer a free fitness consult if you're a new member which was really helpful. The trainer and gym staff are great and really do a good job at keeping up the place and helping members out!
    Overall great stock of free weights open studio space and machines. I'd say it's above average in equipment because I haven't had to wait for machines really even during peak gym times.
    They have a lot of options for classes like martial arts, workouts, HIIT, yoga and beyond so if that's your thing you won't be disappointed.
    They also have really good locker rooms with both a steam and sauna which sets it apart from other places as well.
    Of all the gyms I've tried in Cambridge so far I'm glad I chose this one. It has everything I need and more.

  • Great facility! People are very nice, staff always welcomes you with a smile, equipment constantly updated.
