Who Is GlennSpin?


Hey Guys! My name is Glennis Seldon. I am the Owner of GlennSpin. I am a life lifelong athlete and a lover of all things health and fitness.

From a young age fitness has been a major part of my life. I grew up in Long Beach, California where I was introduced to fitness through Track & Field/Cross-Country at the early age of 8. I competed up until my senior year in college. I graduated from Oral Roberts University in 2007 on a full ride track scholarship.

In 2009 I decided I wanted to start competing again. I hadn't train or raced for nearly three years, and as a result I gained a little over 40lbs. I figured that the easiest way for me to get back in shape would be to join an elite track team. I assumed I could pick up where I left off. Boy was I wrong! I had to learn a lot about the importance of nutrition and how to properly care for my adult body. 

I competed as an elite/professional runner for over 4 years. In 2016, a few months before the Olympic Trials I injured my Achilles and wasn't able to recover. I made the tough choice to stop training all together and haven't raced since then. After my track career ended, I naturally went into the fitness industry. I became a personal trainer and started helping my friends and family reach their health and fitness goals.   

Outside of being a lifelong athlete, I am a Realtor, a Orangetheory Fitness Coach, and a XC/Track & Field coach at a my Alma Mater, Long Beach Wilson High School. I enjoy giving back to my community and love being a role model for the youth.

Being an athlete instilled in me the discipline, commitment and work ethic it takes to accomplish any goal in life. I enjoy inspiring women and showing them that it's never too late to accomplish anything, thus is how GlennSpin was created. It brings me so much joy supporting people as they progress through their own health & fitness journey.
