We are a private fitness club “for women only” offering an alternative to the traditional gym.  No fancy machines here, just fun group fitness classes.

Our studio offers premium commercial sound equipment, infectious music, and dance lights, before you know it you will find yourself engulfed in the music and shaking your booty.    

You will see results much faster at working out in our group fitness classes because they are more fun and you will want to come back for more.  The average hour spent on a treadmill burns 300 calories compared to 600-900 calories in a group fitness class.  And, it goes by much quicker because you are not bored, it is actually fun.     

During our classes you will engage a ton of muscles (blissfully) unaware that you are incorporating traditional fitness moves like squats and lunges into your choreography.      

When a work out feels like “work” we understand it is hard to get motivated about coming back to do more.  Our women only fitness classes are so enjoyable you actually look forward to your next class.         

We have had women loose well over 75 pounds coming here, just because they were having fun.  A lot of women would not be going to the gym at all if it was not for our crazy group fitness classes.      

Whether you are just starting to get your body moving again, or you are a serious pro, you will enjoy our group fitness classes and our challenging workout.  All of our classes can be adapted for any fitness level.       

With the combination of Flirty Girl Fitness®, Zumba® and Pole®,  The Underground Fitness Club, Inc. offers women over the age of 18 a high-impact total body workout in which strength, endurance and flexibility are trained in an intensive but fun new exciting way!
