Without fitness centers, action movies would be filled with scrawny actors and completely devoid of heroes chasing down criminals on treadmills. Get your heart racing with today's Groupon: for $69, you get a one-month membership with unlimited classes (up to a $99 value), a one-hour massage (a $60 value), and a 30-minute personal-training session (a $35 value) at Alameda Athletic Club in Alameda (up to a $194 total value).

Members of Alameda Athletic Club make use of cardio equipment, free weights, and exercise classes before rewarding their taxed bodies with restorative massages. A one-month membership unbars a fitness fortress, as members gain access to cardio and weight rooms and an unlimited number of classes, including Pilates, yoga, and TV repair. Zumba sessions bounce to the beat of Latin rhythms, and boxing classes arm students with self-defense. Women can sweat and strive in the private exercise room, and all members can enjoy an invigorating spell in the sauna.

A certified massage therapist treats muscles to the client's choice of kneading style during a one-hour massage, which can employ techniques such as Swedish, sports, deep-tissue, myofascial, or air-bongo massage. During a 30-minute personal-training session, a fitness sergeant guides the trainee through a workout routine that focuses on the individual's fitness goals.
