My name is Nicholas Walejeski and I have been involved in the fitness industry since 2004. I have group and individual clientele ranging from college level athletes looking to increase sports performance, to older populations looking to increase quality of life. I have a passion for the fitness and wellness industry and believe that in order to successfully change one’s fitness lifestyle, one’s current psychological abilities must be challenged and changed as well. I have a Bachelor's degree in Psychology from Cal State San Marcos and have held multiple nationally recognized personal training certifications (NCSF, NESTA, NASM).

I believe in a holistic approach to fitness and wellness where my clients not only re-shape their bodies, but they re-shape their thoughts and attitudes towards fitness. I have competed in college level volleyball and have coached Men's Varsity Volleyball at Davis High School. I am experienced in developing personalized weight loss programs, resistance training programs, hypertrophy training, core training, polymetrics, functional training, post-injury programming, and special population training. I have been leading indoor and outdoor boot camps for over 5 years now and am continually impressed by the repeatedly developing abilities of my participants. Triathlon training has developed into one of my most successful fitness programs where people develop into a brand new sport and build lifetime friendships with fellow competitors.

I have been leading the triTRAINed triathlon training program in Davis since 2010. Each year we grow stronger and represent deeper within the triathlon community. We are a goal oriented program and are proud to train a wide range of athletes; from first timers looking to complete their first triathlon, to consistent top three podium finishers. I hold a Level 1 USAT triathlon certification. Please take a minute to read our success stories in the Before and After section.

I like to bring a fun and creative edge to my fitness programs where your current levels of fitness are challenged in new and exciting ways. My passion for fitness and wellness is contagious and will become ever apparent as I guide you to your fitness and wellness goals the quickest and safest ways possible.

ACE: Certified Personal Trainer, NSCA: Certified Strength & Conditioning Specialist B.A., Sociology, Sonoma State University, Credentialed Physical Education Teacher, Former DHS Assistant Varsity Baseball Coach

Fitness has always been a part of my life. As I grew up in Davis as a young boy I was an avid baseball, basketball and soccer player and loved the thrill of competitive sports. As I went through high school and into college, I realized that baseball was my true love and to excel in my passion I needed to focus on getting into shape, which meant getting serious in the gym. It was during my junior year of high school that I started strength training and working on my cardiovascular fitness. I was hooked. The way that exercising made me feel was unmatched by many other aspects of my life and I now want to spread that feeling.

I am realizing every day that fitness is my passion and I love passing on the vast number of advantages that come with an active lifestyle. I am a Certified Personal Trainer through the American Council on Exercise (ACE) as well as a Certified Strength and Conditioning Specialist through the NSCA. These two certifications give me the knowledge and skills needed to train the recreation fitness enthusiast as well as competitive athletes.

If success in sports is what you desire, I can be the person that helps you achieve that goal, but that is just one aspect of my skill set. I enjoy helping others get comfortable in a fitness setting, losing weight, gaining muscle, improving balance and mobility, or any other goal that you may have. I live my life in a way that promotes health and longevity and encourage others to do the same. I realize that sometimes life gets in the way but when it does, I will be there to help you persevere. I welcome challenges, whether I am helping someone lose weight who has previously had little success, or training someone to compete in an event that they never thought they could before. I encourage you to follow your passion, develop goals, and reach for things that you thought were out of your reach before. Let’s get fit and lets do it together.

Derek Haff

Derek Haff Book Now

NASM Certified Trainer | B.S., Business Administration

Are you looking to lose weight, get fit, or increase the intensity of your training regimen but perhaps need a little guidance, encouragement, or motivation? My name is Derek Haff, and I am eager to help you meet all your fitness objectives. While I am new to personal training in the professional sense, physical fitness has been at the center of my daily activities for as long as I can remember, and it has always been among the top priorities of my life. I have been involved in many aspects of athletics, having played football for many years as a youth, softball as a young adult, and have been studying the art of karate for the last couple years. Throughout, I have been highly devoted to all aspects of fitness, including weight training, aerobic exercise, and nutrition. My family has been members of the various manifestations of Get Fit Davis for about 25 years now; in fact, from the time that it first opened, and I have been working out here since I was 14 years old.

I earned my bachelor’s degree in Entrepreneurship from Sacramento State University in 2015 and I have decided to devote my time and energy to the thing that I am most passionate about: fitness. Towards that end I concentrated my efforts during my final semester of college to obtaining my N.A.S.M. certification as a physical trainer. Although some might say that physical fitness is not a career, those who dedicate their lives to fitness know that nothing is further from the truth. Given the aging population and the obesity epidemic, fitness is clearly an area with unbounded potential and opportunity. Devoting myself to help others achieve their fitness goals gives my life purpose beyond what could typically be achieved in the business environment.

Whatever your fitness goals may be, I can assure you that as your personal trainer, achieving those goals would be my highest priority. Your success will give me great personal satisfaction, and I will leave no stone unturned in making sure you become as fit as you want to be. I hope that my enthusiasm for fitness will be contagious, and you will embrace physical fitness as your main focus in life as I have.

Ashton Wolgast

Ashton Wolgast Book Now

ACE Certified Personal Trainer

Hey! I'm Ashton Wolgast, a Certified Personal Trainer through the American Council on Exercise. While my professional title is new to me, I've had a passion for fitness that’s lasted a lifetime. My mom, Honey, always had my brother and I signed up for sports, dance, and anything else that kept us social and active. As a kid I started out with gymnastics and cheer leading. Now I know what you're thinking "cheer leading... really?" However, all stigmas aside, our coaches were tough. Cheer taught and helped me improve my strength training, conditioning, coordination, technique, and agility. It's what got me started. Then, after cheer, I stayed interested in fitness and exercise because of the many benefits of an active lifestyle. In fact, because of my workouts, I went through a total mind and body transformation. This new mindset is the one I want to pass on today.

Over the years I’ve learned and practiced many different methods of training. I started with high-intensity interval training (or HIIT) with calisthenics and plyometrics, then worked my way to powerlifting here at Get Fit Davis. Working at Get Fit Davis has granted me the extraordinary opportunity to train and pass on my passion for fitness. Every day, I gain experience and knowledge from others in the industry. I get to train with Coach Nick Walejeski in the triTRAINed program and with Coach Colin Schmitt in the Davis Boxing Academy. Both of these mentors help me learn new skills and better my training approach as I add to my "fitness library". Currently, I've been able to develop my own style for teaching fitness through instructing boot camps and leading group fitness workouts.

My fitness philosophy is to balance workouts, the same way you would balance a diet. I believe it is crucial to train in a variety of ways in order to learn what works best for you and to keep every part of you fit and healthy. My ultimate goal is to help people figure out how they like to get moving so that they can see their workouts in a way that gets them excited about having an active lifestyle. If you have a weight loss goal, want to look more toned, or just want to feel better during your daily life, I can help you find a program that suits you and helps get you excited about physical fitness. Your fitness is something that will change the way you think like it did for me. You will be more interested in your time-management, food, sleep, and self- improvement in all other areas of your life. Coming to the gym is fun for me. It's a chance to be better than I was the day before, a chance to practice a new skill. Overall, it's a chance to keep learning about myself. Being able to work out is not just a box we have to check off at the end of the day. It is a privilege. I want to help others find that feeling, and am so excited to have that opportunity!
