Prior to working full-time at No Excuses, Brandon worked as a sports writer for the Gwinnett Daily Post, covering prep sports.

In Brandon’s own words: “Once I went through my first CrossFit workout, I knew that was the workout regimen for me. It combined all the workouts I was used to and added new, fun, exercises to it. CrossFit allows me to compete with myself, others in the gym and the clock.  I’ve lost more than 60 pounds from when I was a college offensive lineman. Many of my weightlifting numbers are similar to when I played football. The biggest difference is the addition of multiple pullups, pushups and situps to my workouts.”

Additionally, Michael was solicited to train at the national level with the United States Judo Association following his Tennessee State podium finish in 2006. However, he declined to pursue a commission as an Officer in the United States Army.

Michael went on to attain a Bachelor’s of Science from the University of North Georgia and Commissioned in the United States Army in 2010. Michael was in the Army for 8 years and attained the rank of Captain during that time. Michael served as a Company Commander, Urban Search and Rescue Team Leader, and Country Engineer for 5 East African countries.

Additionally, he acted as Physical Training Officer for the Maneuver Captains Career Course at Fort Benning, GA.

After 2 deployments and 8 years of high tempo operations training, Michael decided to leave active duty to pursue his passion for health and wellness and is currently pursuing a Doctorate Degree in Physical Therapy while also fulfilling his commitment to health and fitness at No Excuses CrossFit as a Trainer.

“Before CrossFit, I struggled to maintain consistency in training. I dealt with confidence issues and generally was not living a healthy lifestyle. Having a measurable, repeatable, and constantly varied training program kept me on track and interested in my workouts. You can see the results in the mirror, in your life, and in your ability to perform better daily. I know that for so many people fitness is more than just working out, it is about conquering something within themselves. No one fights a battle as hard as the one within their heart, and for many people, that is tied to their appearance and physical performance. For me, CrossFit is what sparked my passion for health and wellness and the impact of that has changed my life.”

Rebecca Boskovic

Rebecca is a recent transplant from Illinois, arriving in Suwanee, Ga., in search of sunshine and the rich culture of Atlanta.

As a mother of three daughters and a son, ages 15, 12, 8, and 5, and married to her husband Michael of 20 years, Rebecca understands the power of exercise, healthy eating, and adequate rest to allow her to feel her best — physically and mentally — to care for her family.

After working out in traditional gyms during her 20s and 30s, it wasn’t until she discovered CrossFit in her 40s that she was able to achieve the level of fitness she enjoys today.

As a true convert to the power of constantly varied, high intensity, functional movement, she obtained her CF-L1 and CF Kids Certs within a year after starting, and continued her education with CF Gymnastics and Aerobic Capacity Certifications in the year following. Likewise, she became an avid believer in the benefits of mobility training to reduce injury and allow for correct muscle usage during foundational movements. To build her knowledge, she has received over 32 hours of continued education related to mobility training, and has an arsenal of exercises designed to keep your feet, knees, hips, shoulders, and spine supple and pain free, and your glutes, hamstrings, and scapula ready for proper activation.

Over the past four years, she built and ran a thriving CF Kids and Teens program, opened a garage gym at her Illinois home, and now has a garage personal training studio here in Suwanee. Having her business, The Fittest Me, run out of her garage gives Rebecca the flexibility to train while still being attentive to her family. She trains athletes of varied levels, ranging from self-proclaimed exercise haters to professional basketball players, to achieve the goals that are most prized to them.

She believes that we all have a life purpose, and that we are best equipped to live out our calling when we lead with strength while feeling good about the body we’re in. Her motto: “Strength for Life ~ in a body you love”.

In joining the coaching team at No Excuses CrossFit, Rebecca brings a passion for strength, mobility, and whole foods based nutrition to maximize the potential of each and every athlete…through classes as well as by serving those who value targeted results only possible through personalized training.

When asked about CrossFit, Jeremy said: “At the age of 33, I was a heart attack waiting to happen. I was a horrible example of health and fitness for my young children. Then I found CrossFit and my life will never be the same. Not only am I stronger, leaner, and more fit than I’ve ever thought possible, but I’ve found my life’s calling.”

“Now, I want my life to be about helping entire families get healthy, fit, and strong. I want to show them the magic of CrossFit.”

“When describing CrossFit to someone new, I haven’t found the right words to adequately describe how a CrossFit workout can simultaneously feel so horrible and so awesome, all at the same time. But I know for sure that there is no better feeling than seeing the sense of accomplishment on a newcomer’s face after completing their first CrossFit WOD.”

“I had never weight trained in my life, so joining CrossFit was a new world to me. I trained through one pregnancy and have since worked very hard to grow as an athlete.  And now, I have competed in countless CrossFit and Weightlifting competitions.”

Glen Wilkins

Glen grew up in Albuquerque, NM, where he swam and played baseball in high school. During that same time, he was either on a skateboard, snowboard, road bikes or mountain bike. He raced mountain bikes competitively all over New Mexico, Colorado and Arizona during high school and college.

Glen loves to engage with all of the members and build a personal relationship with everyone who walks through the door.

In Glen’s own words: “I had not been very physically active since racing bicycles competitively. December of 2012 my wife did a CrossFit workout with my sister in Austin, TX and was completely wore out from a fast WOD of air squats, running and kettlebell swings in a neighbor’s garage. My wife was hooked and invited me to attend a class with her at No Excuses. I reluctantly went with her and agreed to join. I was determined to not change my diet, but still workout. After losing some initial weight I realized that diet plays a huge role in a healthy lifestyle. Since then I have lost close to 45 pounds and I’m stronger than I have ever been. I love everything about CrossFit from the Olympic lifts, powerlifting, gymnastic movements to the healthy dietary change. My wife and I were very serious about our two sons being active and healthy, but at the same time we would sit at their baseball games and eat food that was bad for us and get fat. This was a big eye opener for the both of us. The CrossFit Community is a very welcoming community and I want to share what I have learned and accomplished with anyone who will listen.”
