I believe in CrossFit as a daily life “enhancer”. What do I mean by this? Anyone can do CrossFit! Yes, anyone. Any age and any physical shape. Ask yourself these questions: Do you sit down and stand back up? Do you pick up your child or a bag of dog food? Do you carry your groceries into your house? Do you pack things into the top shelve of your closet? Well, I hate to tell you, but you are doing the nine foundational functional movements on a daily basis, and that is exactly what CrossFit is about. I want to make sure you do all these movements in a safe way, so you may continue with your exciting daily chores. CrossFit is defined as, constantly varied, high intensity, functional movement. What does this mean? We never have the same workout twice, we make sure you work very hard, and that you stay safe while doing it. At our Box, we have the belief that every person is an athlete, that every person will be given the appropriate time and attention needed, and that every person leaves our Box with a sense of accomplishment and pride. CrossFit teaches you about your own physical strength but more importantly, about your mental strength and toughness.

Yay fitness! This pretty much sums up my attitude about CrossFit! 

My CrossFit journey began in 2014 by being invited by my younger brother, Evan and his art teacher, Miesse.  Since Michael and Silvia have taken me in, showed me an immense amount knowledge, and inspired me to take my health and fitness to paramount levels, I found myself being a CrossFit coach. I love the encouraging community and seeing people from all walks of life come together. It is such a reward to see people transform, not just physically, but also mentally and emotionally. Simply thankful to be apart of such a wonderful gym, and cannot wait to see what it becomes.

My passion for fitness and nutrition began early on, by my teens I was spending several hours a day cheering, tumbling, and running. I continued my pursuit for knowledge in this area in college, receiving a B.S. in Exercise Science from Tarleton State University, a Fitness Specialist Certification from Cooper Institute, Physical Education Certification through the Texas Education Agency, and a Kickboxing Certification through American Nimpo Kempo.  I have since received my Masters in Educational Leadership from Lamar University, where I even managed to tie my passion for exercise and wellness to education and wrote my thesis on the benefits of providing school district employees with wellness programs.  

I love to challenge myself, which has led to experience in many different sports including marathons, triathlons, cheerleading, kickboxing, running, weight lifting, rucks, and mud runs, but when my husband introduced me to crossfit in 2009, I was hooked!  Crossfit was/is the total package, it combined my love for exercise science (yes, it is a science) and my life-long quest for optimum nutrition.  Needless to say I threw out my “fat free” cook-books and replaced them with recipes that combined fats, carbs, and proteins correctly.  I couldn’t believe it, I was eating avocados, nuts, seeds, and beef (items I had deprived myself of since Jr. High) and I was actually loosing fat and gaining muscle!   The community and the intensity of the WODs drove me to get better, the new elements challenged and empowered me, and the variation kept me interested. 

I love the transformation I have seen in others through crossfit.  Crossfit makes people stronger both physically and mentally.  People start working hard in the gym and suddenly they want to clean-up other aspects of their lives as well.

Having been diagnosed with hypertension and high cholesterol at the age of 32, I knew I had to change my lifestyle. Not being active throughout my entire life, it was very difficult to find an activity I could fully enjoy. I started walking, which turned into power walking, which turned into jogging, and soon enough I was bored and needed more stimulation. I came across CrossFit through some friends and it was love at first “workout”, this was in 2011. After doing CrossFit on my own for some time, I thought I would give a professional CrossFit Box a try and see what all the fuss was about. I advanced more within 6 months with professional coaching than I ever had on my own. Having proper coaching makes the difference in many ways. A coach is able to keep you safer due to watching your movement, give you necessary encouragement and most of all, you build a community like no other. Soon you speak the language: “What was your WOD time? Did you PR? How many HSPU did you do?” CrossFit has become more than just weights, distances and times to me, it became a second family.
