I was born and raised in Arlington, Texas and attended Arlington Martin High School where I participated in football, and shot put. After graduating from high school I continued my "fitness" goals at Gold's gym for the following 4 years where redundancy and monotony knew no bounds.  While working as a paramedic for Robertson County EMS, I saw a clip from the 2010 Crossfit games and was impressed despite their "swinging pull ups". Having done one CrossFit workout a few years prior and remembering the agony it brought me, it dawned on me that I should venture into these unfamiliar workouts. I began doing my own workouts at the station consisting of box jumps on the back of the ambulance, burpees and Kettlebell swings with random "heavy" objects. After a few weeks I realized this would no longer be sufficient if I wanted to get serious about it, so I joined my first CrossFit gym in January of 2012 and never looked back. After drinking the "kool-aid" I realized I was extremely passionate about CrossFit and my new journey of fitness and got my CrossFit Level 1 Trainer Certificate. With my constant thirst for knowledge of fitness and nutrition I hope to share the knowledge I have accumulated. In 2013 I started the CrossFit portion of the "Texas Summer Firefighter Games" held annually in a preselected city where firefighters come together from all over the state to compete in a myriad of games and sports in hopes that my portion would spread due to the high volume of firefighters, EMS and police officers that participate in CrossFit. I spend the majority of my days off from the Midlothian Fire Department coaching or working out at CrossFit G6.


Corey has a love of CrossFit and a desire to constantly compete that is only surpassed by his passion for helping others accomplish their goals both in the box and in life. He sets a high standard for himself in all aspects of life, including his health and fitness, and expects others to do the same. He can often be found in the box outside of his coaching hours either working on a particular skill or pushing himself through a grueling workout. As a current student at the University of Texas at Arlington pursuing an MBA and Masters in Economics Corey juggles school, work, coaching, and his own athletic endeavors. However, as time consuming as all that may be, he never misses a chance to ask someone how their day has been or if he can help them work toward that first muscle up or handstand pushup (his personal favorite exercise). He strongly advocates not only consistent exercise but also a good diet, and also owns the meal prep company "WOD Market". Corey's hobbies include CrossFit, baseball, football, snowboarding, playing guitar for his friends, and grilling out by the pool.

My name is Justin Sibley and I grew up in and graduated from Midlothian. I have been lifting weights since I was 15 years old and have almost always had a passion for fitness.  I played every sport I could growing up but ended up sticking with soccer throughout High School.  I went on to get my bachelor's in Business Marketing from the University of Houston in 2007 and immediately moved back to DFW.  I did bodybuilding style workouts throughout college but for a long time I had been looking for something different.  I went through streaks in my life where I had stopped working out (fill in excuse here).  Then the breaking point finally came - I had become sick of going to the gym and went through the longest streak of not consistently going to the gym in my life.  About 6 months went by and I barely stepped foot in the gym and I saw myself getting more and more out of shape and unhappy about how I felt everyday.  I had heard about CrossFit from one of my younger brothers (Nathan) several years before but never gave it a chance.  Finally after some encouragement from my wife Toni (who had been wanting to try it for a long time) we decided to give it a shot.  We went to G6 at 6 AM in May of 2013 and did our first workout.  WOW is all I could say after I finally picked myself up off the floor after it was over.  I was hooked!  How do I sign up?!  We held on to our Globogym membership at LifeTime for about 3 months thinking maybe we would go there ever so often.  Nope! Only time we went back was to cancel our membership!  From that first workout on my wife and I have been obsessed with CrossFit (ask any of our friends or family - lol).  My only regret is not listening to my brother when he started CF.  I want to state that there is nothing wrong with the regular gym, zumba, boot camps, etc. if you are getting results and ENJOY it.  I got results for a long time and built up a strength base that has helped me in CrossFit and life but working out because you feel like you HAVE to and working out because you LOVE it are two different things!

      I went and got my CrossFit Level 1 in November of 2013 because I  wanted to get better at CrossFit and knew I would enjoy coaching other athletes.  Then the chance came to buy the box!  I had always dreamed of owning a gym but didn't think it would ever become a reality!   My wife and I dove in head first and we became the owners of CrossFit G6 in January 2014. I am so thankful for this opportunity to help people get what I have received from CrossFit.  Not only strength and endurance, but friendship and a passion for life as well.  Our coaches and members are more than people we workout with.  They are our CrossFit family and now some of our closest friends outside of the box!  CrossFit G6 is what I like to call the "perfect storm" of busy motivated people.  I work full time as a sales rep selling and renting construction equipment for Holt CAT so you normally won't see me from 8 - 5 Monday thru Friday.  This works out pretty well though because we only have one class and some open gym time during normal business hours.  You can catch me working out in our group CrossFit classes and then coaching almost every afternoon.    CFG6 is the Sibley way of life now.  Often times you will catch my wife (Toni) walking in the door with our daughter Eva to come see daddy coach or workout but also just to hang out with friends.  That might sound strange to anyone that doesn't have a CrossFit home but these people are our friends and family now.  Who doesn't want to hang out with awesome friends everyday?! Think about what it is like when you go to the gym in the morning or afternoon now... Do you think of it as something you have to get done so you can check it off your list?  Or is it something you look forward to?  I still get excited everyday about the workout I am doing at 6 PM.  I can hardy wait for the phone to stop ringing and to head to the box!  That is what CrossFit is about!

Brad & Nicole Horner

My name is Barbara Hampton, and I was raised here in Arlington, Texas. Growing up I played volleyball, ran track and cross country. Then in high school I swam for the varsity swim team at Martin High School. After high school I transitioned from swimming to working out at the gym going through leg, arm, and back bodybuilding style workouts. After a few years of that I had seen results, but I eventually became bored with my weekly routine. I had some friends and family that had been doing CrossFit for a few years and it seemed like something new to try out, so in March of 2015 I finally decided to give it a shot. After my first WOD, I was instantly hooked. I loved the competitive side of it, but I also loved the progress I had seen, and realizing what my body was capable of. In late August of 2015 I joined the G6 family, and received my Level 1 three months later. CrossFit and CFG6 has become a huge part of my life. The people that I met started out as my friends, and have turned into family. Everyone is there pushing each other and cheering each other on. I love being able to not only get in my own workout, but also to be able to coach our athletes and help them reach their own goals. The most rewarding thing to me about being a coach is having a member come up to you and tell you that they finally reached their weight loss goal, or witnessing someone PR a lift they’ve been working towards for months, or seeing the biggest smile on someone’s face after they get their first pull up! I couldn’t imagine spending my time anywhere else but G6, and I feel truly blessed to be apart of such an awesome community.
