While dressing like a mime and lifting imaginary weights may be entertaining, it lacks the synergic power of a group fitness class. Get the most out of a trip to the gym with today's Groupon for fitness packages to Healthworks Fitness Centers for Women, redeemable at five locations in Back Bay, Cambridge, Coolidge Corner, Chestnut Hill, or Salem. Choose between two options:

• For $24, you get a 24-day pass (a $226 value).
• For $24, you get one group training session (up to a $78 value), valid for TRX TEAM, HWX, BURN, Pilates Reformer groups, GRAVITY, boot camp, or intro to drop10. Regular members of the gym can take two group training sessions with this option.

Healthworks Fitness Centers for Women tones bodies and feeds self-esteem meters with a wide-range of exercises classes, top-of-the-line exercise equipment, and talented trainers in this women-only fitness sanctuary. Activate the 24-day membership at one of five Healthworks locations and begin the burn on a number of cardio equipment pieces, most outfitted with a private TV to fulfill dreams of jogging through a morning weather report.

Fitness freaks who are regular members can drop in on a complimentary class, and everyone can try courses such as Cardio Caliente and Fusion Strength to find their own heart-pumping groove. Classes are available every day of the week, with a wide variety of hours to accommodate early risers, working moms, and anyone who loves to move at exactly 12:15 p.m.

Ladies with more intense work-out goals can enroll in the one of the group training sessions with specialized sweat breaking regimes. Explore the fine of art of suspension training with the TRX Team Training Camp, master resistance principles with HWX training, or reduce stress and bulk up grace with Pilates Reformer groups. No matter where calorie-busting leaves energy levels, take advantage of the locker rooms, saunas, steam rooms, and whirlpools, and enjoy this relaxing XX-chromosome health haven.
