Having been involved in sports and fitness in some way for most of my life, I was naturally excited about starting Going Strong 805, and to create a unique and synergistic exercise program for adults of ALL ages.

Although basketball was my passion all through school, it wasn't until the mid 1980s that I discovered bodybuilding, but more specifically, strength training and its numerous benefits. I remember joining the local gym, buying all the books and magazines I could get my hands on, and following the greats, like Arnold, Corey, and Rachel through their careers. At a time when aerobics was the talk of the town, I found it fascinating to be able to achieve similar, if not, greater benefits using dumbbells and my bodyweight. I can recall how quickly my body took shape, yet the scale showed a very small weight difference. I witnessed firsthand the power of resistance training, and I believe no program is complete without including a strength building aspect.

The motivation to embark on this new Journey was born out of a desire to continue on the fitness path I had started and grown to love alongside the great friends I have made through 805 Boot Camp, which sadly closed its doors in June 2017.

Fitness is about much more than the activity itself. 

It's about much more than working out and eating lots of fresh fruit and vegetables. It's about doing these things together. It's about the deep and lifelong friendships that develop as you work on similar goals and encourage each other. It's about serving others and making them more important than yourself. 

This is what my desire is with  Going Strong 805 - to have a welcoming program, where the people are involved in each others' lives, where we build each other up, and treasure every day that we are given. As our Family grows, my hope is that we can build on this solid foundation  through each season of our lives, and keep Going Strong - together!

Faced with a high blood pressure and pre-diabetes diagnosis, Diane decided to take control of her health. She began keeping a food journal and walking. Walking led to joining a gym, which led to outdoor fitness and eventually a 50 pound weight loss. Never having run a mile in her life, she caught the running bug, and has completed numerous street and trail races. She made many new friends and found that helping others in their fitness journey fills her heart with joy. "Strength is independence."

Leah developed her deep roots and passion for fitness at the young age of 6 when she first started her journey as a runner through her youth Track & Field and Cross Country Team.  

Leah transitioned from youth programs to high school where she graduated as a 4 year/3 sport Varsity Athlete (Cross Country/Basketball/Track & Field).  Earning Athletic Scholarships to compete in Cross Country and Track & Field first at College of the Canyons and then transferring to California Lutheran University, Leah focused primarily on Hurdles, High Jump, and the 4x100m Relay.  Throughout her career, she was fortunate to be trained by and with some of the best, including Olympic Medalist Athletes and Coaches. In 2003, she finished her College Career as a member of the 4x100m Relay Team that made All – SCIAC Selections.      

After College, Leah became a coach at her hometown youth track club, STORM as a way to give back to a sport that has played such an important role in her life journey. Her passion for running and fitness continued  the completion of her first marathon in June of 2008 at the San Diego Rock and Roll Marathon. The same year she completed the Chicago Marathon, raising funds for St. Jude Children’s Research Hospital.  This sparked a deep desire to use her passion for running to help others.  In 2009 she began volunteering as a support coach for S.O.A.R (Students Off and Running), a non-profit group that mentors At Risk high school students to run the L.A. Marathon.  Leah has continued to compete in Marathons and Half Marathons across the country to this day.  From San Diego to Sacramento, Chicago to Florida (where she completed the Disney Goofy Challenge - 1/2 Marathon Saturday, Full Marathon Sunday), to her most recent finish in the 2016 New York Marathon just 13 months after giving birth to her son, Joseph.     

Leah understands the importance that strength training and conditioning play and how the two go hand and hand with running. In 2013 Leah evolved in her Fitness Career to instruct at an outdoor bootcamp, 805 Bootcamp.  Her love for assisting others on their journey has only grown and evolved over the years, which is why she decided to take a leap of faith in 2017 and evolve in her passion to help others by creating Simi Evolve Fitness and the Team Evolve Running Club. She is committed to continuing to help others fall in love with running and fitness, pushing for the best possible performance, no matter what your level.
