About Our Trainers
I started Core Fitness and Nutrition in 2003 with the intention of helping people live happy and healthy lives through fitness and nutrition. This is my passion and my purpose in life. Whenever a client accomplishes their goals, it still gives me goosebumps after all these years!

My health and fitness journey started as a young child with a very active young mother and her health-conscious friends.

Loveland Personal Trainer Heather Reilly
Donna Eldridge, Certified Personal Trainer, Fort Collins
I started my fitness journey in high school with volleyball and softball athletics, and my love for fitness has continued ever since. I have over 15 years of certification experience in one-on-one personal training and group coaching along with nutrition counseling. I also am certified as a specialist in exercise endocrinology. I have worked with all age ranges and my training has included special populations. As a female personal trainer, I also bring an unique perspective to my female clients when training them for their individual goals.
I was inspired to join the fitness industry after reflecting on the value and lessons I learned working with a personal trainer of my own. My approach to training relies heavily on the fundamentals of functional training including movements from the actions of daily life that are unique to each individual. My aim is to help find the types of exercises and lifestyle changes that are exciting, manageable and shape a path to achieve goals.
My philosophy on fitness encompasses all facets of wellness to help you become the best version of yourself that you can be. My passions are training and fitness, and I absolutely love helping people smash through their goals and live their best life!

Client Testimonials
Dennis is the best personal trainer ever...truly! After a few workouts, I was doing things I didn't even know I was capable of! I will never train with anyone else. If you're looking for someone to take your money and go easy on you, Dennis is NOT your guy. However, if you want a serious trainer that will work you to your fullest potential and help you meet your goals, give Dennis a call. Not only have I lost weight as a result of his workouts, but, my flat tummy is back! Woohoo! Thank you Core Fitness!!!
At the age of 23, I was diagnosed with POTS (postural orthostatic tachycardia syndrome). Which meant that any form of physical exercise would prompt dizziness and the occasional fainting. Whenever I stood up too fast or got out of bed, I'd get lightheaded and dizzy. As a very active, young individual, not being able to hike, play sports with friends, or make simple positional changes made life very frustrating. Most importantly, for my dream career I needed to get SCUBA certified, but was unable to do so with my condition.
My doctor recommended that I seek out someone to help me with consistent and graduated physical activity to strengthen my cardiovascular system. That's how I came across Dennis Blair and he does a great job creating a plan to help me progress with my physical activity. He is exceedingly thorough and thoughtful when it comes to my specialized training plans. We went from simple exercises on the ground to standing and jumping! I've been working with Dennis for roughly 1 year now and, WOW, what a difference it has made. Dizzy spells and lightheadedness are now infrequent and I've been able to get back into rock climbing, riding my bike, moderate hiking, and get out of bed in the morning. Plus, I am so close to being cleared for SCUBA diving! I could never have gotten to this point without Dennis.
I am so grateful for Dennis and his dedication to helping me get back to the active lifestyle I once had lived and working towards my dream job.
Thank you, Dennis!!
At the ripe old age of 64, I knew I needed to do something to ward off the effects of being undisciplined with my diet and physical activity most of my life. With a strong recommendation from a friend who had had incredible results working with Dennis for a couple years, I knew it was an opportunity I could not turn down:) Now after two years with Dennis as my personal trainer coaching me through 2 workouts per week, I can testify I have not only lost weight, but, more importantly, I am stronger in all areas of my body! The strengthening has allowed me to do things I could not do before (i.e. walking all over New York City). Dennis was sensitive to where I was when I started with him, and, he designed a program personalized to what I needed and wanted. He is encouraging, professional and gets results because he expects results!
