HOMETOWN: Brentwood, NY

My fitness journey began in the mid to late 80's, think leotards and leg warmers, if you can picture that. I started taking classes, which lead into teaching "Free style" floor and step aerobics. I taught for a while, but due to gym closings, family, full time job with the Postal Service, and having to come up with my own choreography, I decided to take a break from teaching. I kept in shape after that, by running and lifting weights. Then one day, a friend told me about this gym that had a class called LesMills BodyPump. I took one class, and that's all it took, I was hooked. I took the class for a couple of years and then decided to start teaching again in 2005. Since then one by one, I have added my other certifications. I love being a part of a person's health and fitness journey, by encouraging them to, push themselves, not give up, and feel proud of what they've accomplished.
Instructing classes, is not my only passion, I also love to run. I have ran a few marathons and half marathons, and I have actually bested personal records as I've gotten older.

LesMills Body Pump-6/2013, LesMills Body Combat-3/2014, LesMills Body Attack-5/2015, LesMills Body Step-5/2015. –One stop body shock Group Fitness Leader. CPR/AED Certified. My husband and I have been together for 15 years. After my third child was born, my mother in law purchased me my first gym membership. We started attending the gym together regularly in the evening. We would run on the treadmill and do the weight machines to the best of our ability. All the while we would notice a group of ladies going into a room to different classes. We were a little intimidated at first but we finally gave the classes a try. That's all it took and we were hooked. Doreen instructed us through Body Pump and Combat. I even started attending classes on Friday (Body Step) Doreen has always been a great inspiration to me. Eventually I became a certified instructor. Now I get to inspire other women on their fitness journey. I look forward to more certifications and more classes with the wonderful friends I have made in the group fitness world.

I love to lead group exercise classes because of the joy it brings me to see people change their lives for the better. When a person becomes healthy and feels good, they can do so much more. They can also influence a new generation of healthy. When I am not exercising with my friends at Flex 24, I am a speech language pathologist for ECISD. I have run numerous 5K and 10K races, 6 half marathons, and completed a full marathon as a personal challenge for my 40th birthday. I also achieved the rank of "green belt" in Kajukenbo Martial Arts at the school of Matthews Martial Arts.I have been married to Gary since 1999 years and we have 2 amazing daughters, Halie and Hannah. I am a proud alum of Texas Tech University.

Hi, my name is Georginna Coss but everyone calls me Ginna! My husband and I have been married for five years now and we have a beautiful daughter whom means everything to us and we hope to continue growing our family and have more beautiful children. I stay at home with my daughter and love every second of it. My second home is the gym! I absolutely love my gym and all the people there. Everyone is so inspiring and motivating that you feel like you are a part of a whole other family! Fitness was not always easy for me. I was always overweight and struggled a lot during junior high and high school with being healthy. It was not until after I got married that I discovered group fitness. In fact it wasn't until after I had my daughter that I truly found what worked for me and that was RPM! Instantly I was hooked and loved the euphoric feeling I had during and after every class. I have been certified for about a year now and it's the best thing that has ever happened to me! I have never felt better! My energy is great and I have been able to maintain a healthy lifestyle. Never beyond my wildest dreams did I ever think I would be a group fitness instructor and leading a class. It makes me proud that now I can motivate and inspire other people the same way I was inspired when I was struggling sitting in the back row of a class and just not happy at all. We learn something new every day and every day is a chance to get better at whatever we do. I love my family, I love my gym, and I absolutely love being an RPM instructor!

HOMETOWN: Ciudad Juarez, Mexico

Credentials: Body Pump 2002, Pilates 2003, Zumba 2009, CX Works 2011, Sh'Bam 2012, Body Attack 2012. I was born in San Jose, CA but was raised in Ciudad Juarez, Mexico. I have been happily married for 25+ years, have 3 beautiful children and a handsome grandson. After God and my family comes my love for working out. I was six years old when my grandfather put me in dance, if it wasn't for him driving me to and from practice, I don't think I'd be so attached to dance. I fell in love dance and continued to pursue dance through my high school years by joining the dance team my JR and Senior year. My family moved to Odessa in 1990. In 2000, I started teaching Step at the YMCA, I figured it was the closest thing to dance and I was able to get a good workout in at the same time. I enjoyed it so much that my dance moves I would add in to the middle of my Step routine would get me into a little bit of trouble. I then entered the wonderful world of Group Fitness with Les Mills in 2002. This is when I went to training for Body Pump. It was the hardest thing I had ever done in my life. The feeling of accomplishment was the best feeling ever! I then pursued Pilates in 2003, Zumba in 2009, CX Works in 2011 and Sh'Bam 2012. In November of 2012, I joined an awesome group of ladies who all went to get certified in Body Attack. This program assisted in the Launch of Group Fitness classes for Flex 24! I couldn't ask to be part of a better gym, this is not only my second job but my home away from home. There is nothing better than to leave work and come unwind with amazing people. I can honestly say that I started teaching maybe for the wrong reasons, struggling with weight is not easy, I wanted to be skinny and toned, until one day it hit me. Why am I doing this? (Life of an instructor is NOT easy!!!) I realized that it might be hard learning a new routine every three months, might suck the life out of you but will never be better if you don't give the members your best effort. Les Mills gives us the tools to do that. I feel in love with the people. The beautiful women that give me an hour out of their busy lives, who come in to feel free, relaxed, becoming healthier and stranger are the best! I love to workout with other people. I love to make people feel connected with one another and just be happy. Zumba is my first workout love but I also love all the classes that I teach and my friends/sisters teach at this gym. Classes are fun, they may be tough at the start but the toughest part is walking into a class! Always give it a go, come in and have fun in a class! Can't wait to see you at Flex 24!

Credentials: Certified Personal Trainer-NASM, Certified Personal Trainer-NPTA, Master Personal Trainer-NPTA, Nutrition and Wellness Coach-NPTA, and CPR certified. 

Hello my loves, my name is Shelbi Samford. Growing up, I was always very athletic. My passion for fitness intensified as I entered adulthood and I learned more about the National Physique Committee. Unfortunately, after I had my two precious daughters, I had to have a hysterectomy because my Adenomyosis and PCOS became unbearable. Going into menopause is never fun, but going into menopause in your early twenties is devastating. I learned very quickly how hormones can effect not only your appearance but also your mentality. I put on 50lbs in about a year. I felt horrible! I made it a top priority of mine to educate myself and overcome the mountain that was in front of me. After extensive research, I decided to get my Certification in Personal Training through the NASM.  Then I received a Certification in CPR, followed by another Certification in Personal Training, Master Personal Trainer, and Nutrition/Wellness Coaching through the NPTA. Fast forward through a year of trial, error, and then success, I am in the best shape of my life! I’m currently in offseason for my first NPC debut along with developing a website for my online coaching, which will launch soon! I am also enrolled in classes at UTPB, majoring in Forensic Psychology and minoring in Nutrition. It’s a privilege inspiring people through personal training and nutrition because I know how the benefits effect every aspect of someone’s life. Self care is essential to manifesting anything in your life, and I am so humbled that my job allows me to extend what I’ve learned to others.
