Having always been an athlete through high school and college, I was really disappointed in my fitness level when I reached my mid thirties. I found myself like many, trying every few months to get back in shape…I would join a conventional gym, stick to it for a few months only to find myself bored and unmotivated. This seemed like an endless cycle….until someone mentioned to me Sergei Karaliou and the Underground Gym.

Training with Sergei and his staff has been an awesome experience. He not only challenges you physically, but mentally. His training tools are primal in nature. We work with sledgehammers, kettlebells, etc. We flip tractor trailer tires. We climb ropes.

Yet his training methods are very progressive and safe. Sergei took me on board when I was completely out of shape and could barely do a few sets of basic calisthenics — today I’m amazed just how much progress I have made.
