Born in Huntington Valley, PA, and having grown up in Westport, CT, Adam Colberg always expressed a deep connection for health and fitness. He also had big dreams of becoming an accomplished professional boxing coach. Adam Colberg did both, through the ownership of his award-winning fitness gym and becoming a pro boxing coach at the famed Gleason’s Gym, in Brooklyn, NYC.

Colberg credits his experience with the U.S. Marines as being a main ingredient to his inspiration, motivation, and personal training success. Colberg says, “ My journey with the Marines was instrumental in creating a “fit lifestyle” for myself. Then, though education and experience I developed the necessary tools to help others achieve the same lifestyle for themselves. This is the gift that continues to keep giving. When you help yourself first, you’re empowered to help the world.”
