While feeling the burn during a workout is generally a good sign, feeling the burn while sitting on the sofa means your sofa is in the fireplace. Engage in controlled, constructive body burning with today's Groupon: for $99, you get a three-month membership, three month-long classes, and unlimited sauna use at 123Fit Anchorage (a $300 value).

123Fit's modern, fitness-centered facility provides a workout haven for people of all fitness levels, with personal trainers available for consultation and an overall focus on health and wellness. Arrange a train-station rendezvous with all of your fitness goals using 123's 30-minute circuit-training program, which alternates between cardio and weight machines to tone the entire body, manage weight, and increase stamina for the chase scene. The circuit workout can also be paired with any of 123Fit's classes—four-session group exercise classes starting at the beginning of each month. To keep muscles sharp and minds limber, 123 members also get unlimited time in the sauna, a therapeutic haven of steam heat.

This Groupon can be redeemed any time within six months, but to take full advantage of classes it's best to register early in the month.
