RCF Experience

The goal of Rock City Fitness is to offer a creative, challenging, focused environment that motivates clients to obtain new levels of fitness and self-confidence.

Rock City Fitness is an exclusive studio that specializes in 1-on-1 and small group personal training. All workouts are by appointment, with a trainer and tailored to your goal. You will always do the right workout at the right intensity!

Owner Eric Maust started Rock City Fitness after spending a decade in the health club industry as the next stage in his fitness training career. Eric's objective was to meet the rising demand of smaller, specialty fitness training studios.


Part of the vision was to merge the qualities of health club personal training, garage gyms and therapeutic-type exercise into one high quality environment. The end result is an effective blend of Eric's industry experience and progressive fitness trends.

We are confident that our unique and recognizable brand raises the bar for personal fitness training. This is accomplished by offering signature programs that aren't available anywhere else and appeal to many types of clients. We want to help you achieve your greatest potential as a person. We believe you have what it takes to do great things!

We offer a complete experience of Great Trainers, Great Programs and a Great Environment.

Clients are directed through a concise consultation and training pathway. Each client learns how Rock City Fitness can help achieve their specific goals with consideration of experience, fitness level and budget. We offer distinctive 1 on 1 training, group training and web-based training programs.

RCF programs include fitness competitions and events. Clients have the chance to compete for a spot on the "fitness challenge leader board" and "wall of fame". We organize training and team participation in local fitness events such as road or obstacle course training.

It's all about working harder and continually moving forward. That's why both our group and 1-on-1 workouts have progressive, multiple training levels.

Rock City Fitness offers a facility and environment that is full of cool vibes and amenities. The materials, lighting, sights and sounds - inspired by rock concerts - tell you this isn't your average gym. Come on in and soak it up!

Not only do we offer a great workout floor, filled with the latest equipment, but also a comfortable lobby area featuring seating, tables, TV's, WiFi, retail area and refreshment station. Rounding out the offerings are a shower, changing rooms and lockers.

We see our role in being part of increasing the overall health and vitality of our neighborhoods and communities. We desire to be a trusted local resource for wellness, health and fitness.

We have three heart standards that we live by: Integrity, Personal Service and Standard Quality of Training.


RCF is operated with sound moral character and honesty. We are committed to meet or exceed all professional standards established by fitness industry leadership. RCF highly values the role of families, therefore implements family friendly business practices. We are concerned with the overall wellbeing of the person not the glorification of the body.

Personal Service

RCF highly values the experience and treatment each customer receives. We know that each client has a unique set of circumstances that has led them to a relationship with RCF. Our goal, within the scope of our practice and care, is to help clients improve their overall quality of life. We hope to bring out the best in each client by cultivating an environment of making positive lifestyle choices.

Standard Quality of Training

RCF cares very much about quality of personal fitness training. RCF is committed to obtaining the appropriate, industry leading personal training credentials. We are diligent to maintain and increase our knowledge in an ongoing basis through professional continuing education activities.

Furthermore, RCF has developed a distinctive approach to fitness training. All trainers will be “RCF certified” in this process to ensure uniform and consistent training programs for all clients. We want to make great opportunities for trainers to learn, grow and succeed in the fitness industry. This is a win/win situation for both trainers and clients!

3-Fold Approach

Training with Rock City Fitness means getting results. Our motto says it all: New Depth. New Strength. New Heights. Our goal is to inspire and help clients dig deep and reach new levels of fitness. Rock City Fitness uses a signature 3-fold approach to make this happen. Our 3-fold approach consists of Movement, Metabolic and Mind. We believe that it takes progress in all three of these areas to be successful.


refers to exercise and progression. The objective of Movement is to achieve results with strength and cardiovascular training. Rock City Fitness uses a system to progressively increase exercise challenge and intensity. Workouts are organized into phases designed to overcome plateaus and even help prevent injuries.

Exercise sends signals telling your body to change which leads to results.
Frequency + Intensity = Increased Fitness Level = RESULTS!


refers to calories and metabolism. The objective of Metabolic is to achieve results through managing calorie intake and expenditure. Weight loss or appearance changes are the net result of calories in vs. calories out. Rock City Fitness designs programs that help manage key nutritional and exercise factors. Our programs will boost your metabolism, burn more body fat, build muscle and transform your body!

Fewer Calories In + More Calories Burned = Transformation!


Mind refers to attitude or mind-set. The objective of Mind is to achieve results by embracing a winning attitude. Client and trainer are equally responsible to make this happen. We believe that you should always do everything to the best of your ability.

The Rock City Fitness mind-set consists of five parts: commitment, effort, excellence, sacrifice and perseverance.
