Jeff Brown
Founder & Owner
CPT Exercise Physiologist
I opened Lex Fitness in 2009 with one goal in mind: helping people reach their fitness goals safely and effectively. I am a graduate of the University of Kentucky with a B.A. in kinesiology exercise science. Beginning my career in 1998, I am one of the most experienced exercise physiologists in the Lexington area. I worked for five plus years in physical therapy and corporate fitness and have been a personal trainer for almost 30 years, giving me a diverse range of experience to help anyone reach their fitness goals
Adam Grosskruetz
Personal Trainer
ACSM Certified Exercise Physiologist | CF-L1 Coach
I enjoy helping people feel strong, lose weight, and get back into shape. Ultimately, helping people reach their fitness goals is my passion. My experience as a personal trainer, group instructor, and coach since 2016 has provided me an opportunity to work with a wide variety of clients pursuing functional fitness, weight loss, pain and disability management, hypertrophy, sport performance, and CrossFit. I value continuing education and science-based methods to optimize functional movement and performance and produce better, more sustainable results for my clients.
Abigail Aydlotte
Personal Trainer
Bachelor's Degree in Exercise Science and Sports Science
As someone who grew up in a family of athletes, my passion for strength and fitness runs deep. I grew up playing just about every sport under the sun, but I loved ballet and cross country running the most. At 14 I underwent spinal fusion surgery for my scoliosis, and while that was quite the hurdle to overcome, it really taught me the importance of mobility and balance. I’m excited for this opportunity to share my passion for health and fitness with anyone who wants to take on the challenge!
Kristian Morgan
Personal Trainer
NASM Certified Personal Trainer
My name is Kristian Morgan! I am a husband, girldad, dogfather, and a big time gamer nerd. I believe that fitness is a journey, and that everyone has that journey in them. I've been an athlete all my life and played basketball in college. Fitness and sports have connected me with so many amazing people, and I believe that everybody deserves to experience that joy. When you have me as a coach, you are motivated and supported as you crush your fitness journey. I passionately believe that living a healthy lifestyle begins with maintaining a strong and fit body. I'll help you combine healthy habits and efficient workouts into a powerful formula to transform. Let's start training together!
Greg Barber
Personal Trainer
ACE Certified Personal Trainer
I have been training clients for over 11 years. I have worked with a wide variety of clients in multiple settings. I specialize in functional movement. I believe in building a strong foundation that will support you for the rest of your life. A strong foundation in fitness is being able to move functionally and do everyday activities pain free because your body has the support that it needs. I train my clients to strengthen all the supporting muscles in the body to protect their knees, back, and shoulders. A strong foundation also includes making healthier choices in diet and sleep.
