Demetz Personal Training About Nathan Demetz Personal Trainer

What sets me apart?

I have a 20 of personal and professional experience, the know-how to apply it, and hold multiple degrees as well as certifications in areas such as online personal training, run coaching, strength and conditioning, fitness nutrition, sports nutrition, exercise science, information systems, and business. These credential come from organizations such as ISSA, ACTION, Indiana Wesleyan University, and Ivy Tech College.

I am not a budget personal trainer and charge what I do for the personal attention you get. While some competitors charge less than $100 per month, you are paying for automated training and nutrition programs, which is not personal training. No part of my process is automated. I personally handle every step of the process.

What our clients are saying:

“Nathan has helped me in my struggle to lose weight. It is a struggle for me because I am not as motivated as I should be. Nathan has helped with keeping me motivated and providing me a training program & nutrition program that will help me to meet my desired goal. They have also helped me with training , at times, and with nutrition. I really like training with Nathan. He is a very positive person, and really is concerned about helping me (& others) with weight loss, nutrition, and keeping a overall positive attitude. I enjoy talking with them about my training & nutrition also.”

What our clients are saying:

“I love the personal training experience you get. I live in Pennsylvania and do not belong to a gym but have workout equipment at home. Grace has created a personal workout routine for me and I am seeing good results! I am so glad I was recommended their program!!!”

What our clients are saying:

I’ve been training with Grace for almost two months now, and I can say that it’s the most effective two months of my athletic life, ever. I grew up playing competitive sports and once they ended, I didn’t know how to consistently train in ways that weren’t tearing down my body. Since starting with Grace, I’ve learned how to develop a healthy, balanced routine. I’m much, much leaner than I was six weeks ago, and have developed an overall healthier lifestyle. Grace is always quick to respond to any questions and is willing to help with modifications of workouts when needed. I enjoy her direct candor and motivational messages. Overall, I definitely recommend DeMetz personal training! Worth every penny.
