Your Coaches

Four Pines Fitness was founded by two fitness professionals who want to share their passion and knowledge with their community.  We are family owned and operated.  

Kris Martinez
Certified Personal Trainer


What sets Kris apart is his passion, his dedication to continuing education, and the fact that Kris has been there, done that, still doing it.  When he started college, Kris weighed over 310lbs.  His college business professor mentioned her little brother had a best-selling book, so Kris picked up a copy.  In this book, “Core Performance," Mark Verstegen outlined specific nutrition and workout strategies, including the four pillars of fitness.  These four pillars are at the core of the Four Pines Fitness philosophy.  Kris applied these nutrition and fitness strategies and transformed his body in 2005.  After graduating San Diego State University, Kris became a certified personal trainer. 

Since 2007, Kris has developed a systematic, results-based approach to fitness which has helped hundreds of clients lose fat, move better, look better, gain confidence, and become functionally stronger.  His clients range from age 11 to 79, professional athletes to super moms.  Spend a minute in the gym with him and you will see, for Kris, this is not a job, this is his calling.  

Kris is the co-founder, program designer, and lead coach at Four Pines Fitness.

Jennifer Martinez
Certified Yoga Teacher, Certified Fitness Instructor,

Certified Precision Nutrition Level 1


In 2003 Jennifer sustained a serious back injury and was out of work and couch-bound for over a month.  Finally, she got some relief when her physical therapist had her walk back and forth in the shallow end of a pool.  She realized staying still was probably the worst thing for her.  This idea stuck- wellness through movement.  We are meant to move.


Yoga became part of her healing process and her way to maintain a healthy back and body.  She soon fell in love with the challenge of Vinyasa Yoga and earned her 200 hr Yoga Teacher Certification,and immediately started teaching yoga throughout the California Central Valley.  


Jennifer is the co-founder, yoga teacher, and nutrition coach at Four Pines Fitness.
