I am not a novice to free weight training, but this was my first experience with kettlebells. Now 72, 3 years ago I was looking for something challenging but safe. Starting with body weight and mobility routines I gradually was able to lose weight, build muscle and now train 3 times a week in an advanced kettlebell class. Sergei and his staff are experienced, attentive and always encouraging while challenging you, making sure that every student is safely performing each exercise. I highly recommend Underground gym for any age but especially those who need to get back in shape or have never worked out before

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.
