Mitch kornberg

I was born and raised in New York and have settled in Nashville for over 25 years. I'm a huge sports fan, particularly when it comes to hockey. I am married with three grown children and two grandchildren. I also enjoy my dogs and cats (usually).

Being a retired police officer and over 50, I understand the hurdles of balancing family and career over time. Aging does not have to mean being out of shape and gaining fat. Together, we can slow and reverse the aging process - you can actually gain muscle and lose fat at any age - in a reasonable amount of time. I have been a fireman, EMT, Coast Guard reservist, and policeman for over 27 years, which means I have made a career out of helping people. This profession gives me the opportunity to put this passion to work in a rewarding way - helping people reshape their bodies, regain confidence and feel better!

When it comes to fitness, I want to make personal training truly personal by listening to and understanding my client's needs, likes, and dislikes. I am a Tactical Strength and Conditioning coach for first responders (military, fire/EMS, police, corrections, etc.),  Certified Special Populations Specialist, TRX Suspension Trainer certified, Cycling Instructor, Kickboxing and a Metabolic Conditioning Coach.



Each individual has their own set of fitness goals. With this in mind I'm able to offer many training methods to suit your needs and lifestyle! If you aren't in the Nashville area, no problem! Please email me directly (mitchkornberg1964@comcast.net) for more information.

"Mitch Kornberg has changed my life for the better. Thanks to just three hours a week of coaching from Mitch, I am stronger and more flexible at 51 than I was at 30. I am leaner, too, having added muscle and decreased my body fat by 10 percent. I still have work to do, but I am proud of the improvements Mitch has helped me make. Mitch is a natural motivator who makes working out fun and challenging. He also has a deep understanding of the science behind fitness. He pays close attention to my concerns and/or any aches and pains, and he has helped me develop good form to avoid injury and setbacks. If you are wanting to make a change in your health and the way you look, I highly recommend training with Mitch Kornberg."

"The workouts I received were tailored specifically to my needs and goals and also allowed me to do them all out home when I did not have easy access to a gym. I quickly saw the results I was looking for and the workouts are interchangeable; I would highly recommend Mitch."

"Mitch knows how to get results! Even if you’ve been working out for years and think you know exactly what you’re doing, Mitch will change your routine and your life! He’s kind, knowledgeable, energetic and fun. Trust me, you’ll be glad you found him!"

"I've been working out with Mitch as my trainer for 3 months. I've lost 35 lbs., increased my strength, and improved my cardio health. I have recommended Mitch to several of my friends and they've had great results as well. 

I have known Mitch for over 23 years and he is a person of character and has a strong work ethic. So, if you are thinking of a trainer, Mitch will help guide through a great workout routine that will get results."
