Personal Bio:

Entering my 28th year as a Personal Trainer this past December 28th, I can honestly say “fitness” has been a major component, as well as, saving grace of my life. From Martial Arts beginning in 1977, to the U.S. Marines 10 years later, I always pursued that which made me stronger-physically & mentally. Now comes October 12th, 1989, a catastrophic knee injury that ended my Persian Gulf tour and my career in the Marines. Numerous knee surgeries, loss of 70#’s and extensive physical therapy, I could walk again but no longer as a Marine. Experiencing my own “success story,” I decided to help others achieve that which they thought impossible by becoming a Personal Trainer. Now having performed over 250,000 workouts with members & clients, personally trained 10,000+ clients and walked as a trainer over 75,000 floor hours, I have been blessed to be a part of so many life altering transformations in addition to supporting my beautiful wife & 4 awesome children. I couldn’t think of a better career!

Fitness Philosophy:

“The body manifests what the mind harbors.”

Megan Benedict Master Trainer


I am a military wife and mother of four with a passion for all things fitness and nutrition. I was always athletic, and my dad made sure I played every sport available – with explicit instructions to keep up with the boys. In college, I didn’t gain the freshman 15, I gained the freshman 40 – despite my participation on the varsity crew team – largely because I stopped listening to my mom’s basic food principles of keeping it fresh, simple, and natural. Since then, I’ve lost the 40 pounds, some of them multiple times after each pregnancy. I am a NASM certified personal trainer and weight loss specialist, Spinning and TRX Sports Medicine instructor, and I enjoy sharing what I have learned with my children, my peanut-butter-and-jelly husband, and you!

As a trainer, and instructor, I work with you and what you enjoy to establish realistic goals and deadlines. My training and group philosophy doesn’t stop at the class or session, I help with grocery lists, general nutrition questions and provide weekly workouts that fit your schedule. Whether your goal is to lose weight, run a race or get strong, you aren’t on the journey alone – let me support you – you may surprise yourself.

Personal Bio:

How does one write about one’s self, well, my fitness journey is simple… It all started in 9th grade as I walked across the track going to basketball practice where I witnessed two senior football players racing, fascinated by their sheer speed and athleticism, it was at that instant where my relentless pursuit of my personal abilities and knowledge began. Now some 14 years later, that pursuit of health & fitness has taken me beyond myself and shifted my focus to that of my life’s mission of inspiring someone to become what they were designed to be-perfect. Perfection is personal, not validated by their body composition only, more that of how they view themselves, their willingness to succeed, overcome obstacles and experience victory in whatever they pursue. Having an infectious training style, I have achieved a high level of success transforming not only individual’s bodies, but also the mindset of no goal is unobtainable when effort is applied.

Vena Villanueva Flexibility Director


I have never considered myself an athlete, but have been physically active my whole life. I was introduced to yoga through Rodney Yee’s “Yoga for Strength” video in 1999 while trying to lose the baby weight and get back into shape after the birth of my 3rd child; ok she was 2 at the time, but the weight hadn’t quite come off! I found that yoga was meant for me and I for yoga – it was challenging and relaxing at the same time as, both for my body, mind, and spirit. Teaching yoga was the furthest thing from my mind, but when my yoga teacher moved, the class begged me to be their teacher. Because of the belief of my teacher and the class in me, I have found a path which has enriched me more than I can say. I started teaching in 2008 and love that I can help people of all abilities benefit from the practice. Being injured in a car accident in 2014 has changed my personal practice and how I relate and help my private clients and students. Recently I have obtained my “YogaFit for Warriors” certification which focuses on healing the body and mind from trauma. Yoga is a lifelong practice and every day is a day to let go of judgement and expectations as well as choosing to live in the present moment. I am the proud mother of 3 children, a son age 23, and two daughters ages 20 and 18; I have been blessed to be able to homeschool them all through high school. I have a wonderful partner, Ted, and we love to travel together. Besides yoga, I am also a licensed esthetician, owning my own business and a Master Instructor in esthetics, teaching a few days a week.

DanHeadShotA little about me: I was born in Alaska in 1990 and my parents moved to Washington a couple years later. With the exception of college, all my life I’ve called Olympia my home. At the age of ten I made my first select sports team and have maintained a high level of athleticism over the past 15 years. Having come through various baseball programs, being a regular starter for the Olympia High School football team, and being an all-state rugby player, I’m no stranger to the rigorous training required to excel at a high level. When I went to university I tried out for the 5th ranked division 1 rugby college in the nation. Not only did I make the team, I earned a starting position and won the most improved award through my dedication and hard work. To end my senior season we played in a packed stadium in the national championship semi-final which is an experience I’ll always carry with me. After graduating I went on to coach the local high school rugby club to a state title, and I am committed to growing this community that I’ve called home nearly all my life. At Rock Fitness my mission is to share my dedication and passion with our clients; and to motivate and inspire all those with goals and dreams that they can achieve them.
Favorite Quotes: “If you’re trying to achieve, there will be roadblocks. I’ve had them; everybody has had them. But obstacles don’t have to stop you. If you run into a wall, don’t turn around and give up. Figure out how to climb it, go through it, or work around it.”- Michael Jordan

“It matters not how strait the gate,

How charged with punishments the scroll.

I am the master of my fate:

I am the captain of my soul.”
