Christine ClarkChristine Clark


Christine believes that in order to stick to a fitness program, it has to be FUN! You have to enjoy the type of exercise that you are doing, or the habit just won’t stick! You have to be able to smile and laugh while you are sweating and pushing past your comfort zone. She also believes that we need to train the body to handle real-life situations: those activities that are performed in daily life (pushing the car door closed, lifting your child out of the car seat, pulling the laundry out of the washer, etc). She believes in teaching the muscles to work together, not isolating them to work alone. Her movement-oriented programs consist of compound, whole body exercises.

Christine began her fitness career as a Spin Instructor in 2001. Next, she became certified through AFAA (Aerobics and Fitness Association of America) and began teaching other group formats like Boot Camp and Body Sculpting classes. After the birth of her daughter in 2005, Christine pursued her Personal Training Certification through both AFAA and the NASM (National Academy of Sports Medicine). She spent many years training clients one-on-one, some of whom she still trains today. During this time, it was rare to come across a client who was not suffering from some type of joint injury or pain. This lead Christine to obtain her Corrective Exercise Specialist (CES) certification through NASM. She was then better equipped to assess her clients to determine specific weaknesses and/or limitations and to determine the appropriate program for that client. In 2007, she discovered the TRX Suspension Trainer. She became a certified TRX Instructor and has kept the Suspension Trainer as a top-ranked tool in her toolbox ever since. A year ago, the TRX Rip Trainer was added too.

She attends numerous fitness conferences each year to be inspired and to keep up to date with an ever-changing industry. Surrounding herself with the best in the industry,  she belongs to the Todd Durkin Mastermind Group and The Results Fitness Mastermind Group to be able to deliver the best that the fitness industry has to offer.

 At FUNction and FITness: through education, motivation, and leadership, Christine assists clients in establishing and reaching their fitness and wellness goals.

Jessica RoseJessica Rose


Jessica Rose just recently received her personal training certification through the National Academy of Sports Medicine (NASM) and is stoked to be working at FUNction and FITness. Though she holds a B.A. in English from Loyola Marymount University, over the past few years she has come to see just how important it is to have a healthy lifestyle (including clean eating and exercise), and decided to change career paths. Having just lost 30 pounds of her own "fluff," she understands how hard it is to swap out pizza for broccoli. She's so excited to apply what she has learned with NASM along with her own personal experience to help others reach their health goals. Her favorite exercise is burpees. Just kidding! It's burpees... with a BOSU ball.

Arianna_copyArianna Arias

  My name is Arianna Arias and 12 years ago I weighed nearly 240 pounds. Due to my weight, I was unhealthy, uncomfortable, and unhappy. I no longer wanted to live that way; therefore, I made the decision to lose weight. It took me a year to loose the first 75 pounds, but then I realized that if I was going to reach my ideal weight and maintain the lifestyle that I wanted, then I was going to have not only lose weight but make it my life’s mission. As such, I began working with a trainer and a nutritionist everyday. Since then, I have through a consistent diet and exercise lost over 100 pounds. It wasn’t easy, and it still isn’t, but I know first-hand the journey that weight loss and maintenance requires; I understand and appreciate the physical as well as psychological demands; and I know that sometimes all someone needs is a partner and a friend. I want to help you reach your weight loss goals the same way that someone helped me reach mine. More than that, I want to help keep you accountable, motivated, and inspired that you too, with help, can become who ever you want to become.
