This Gold’s Gym in Natick (off of Route 135) offers an excellent combination of equipment, classes, and other benefits for both the weekend warrior and the serious athlete. There is lots of cardio equipment available, with televisions all around, so that you can watch television while working out. In the summer, this gym is also kept cool with air conditioning, so you will have no excuses. The free weight and Nautilus area has some serious equipment, but everyone here is friendly and you can make an appointment with a staff member to learn how to use it. Overall, this is a great value.
