Adam and Jennifer Kovacs are long time residents of Sonoma and the owners of Sonoma Fit. Together they opened their first venture Sonoma Cycle Fit in 2014. This small studio, focusing primarily on indoor cycling and TRX was so successful they quickly outgrew their 2000 sq.ft. space and began the search for something larger. By the close of 2015 they found the new location for Sonoma Fit. This new “hybrid” style gym combines all of the intimacy and quality instruction of a boutique fitness studio with the expansive fitness floor (cardio machines, free weights etc.) of a big box gym. This combination of modalities is what sets Sonoma Fit apart from any gym you’ve ever seen. Aside from ownership, both Jenny and Adam instruct classes as well. “We aren’t mere architects of this project, we are in the trenches every day with both our employees and members alike. Fitness and health are a vital part of our every day lives, and we are passionate about imparting those values to the rest of our community.”

When the Kovacs aren’t spending time at Sonoma Fit, they can be found spending time with their 5 children. “Above all, we want to set an example for our kids. Not only about the importance of maintaining a healthy lifestyle, but the ability to build success out of passion. Sonoma Fit is a true labor of love and we want our children to see that with enough hard work and determination, anything is possible."
I have been a Sonoma Valley resident since 2008 and am currently studying business and hospitality at Napa Valley College. I developed my passion for health and fitness after graduating high school, and found inspiration at our original fitness studio Sonoma Cycle Fit. I love the energy of indoor cycling in particular and became a certified Schwinn Cycling instructor. I look forward to increasing my knowledge of the fitness industry and plan on continuing my education through obtaining more certifications in other areas. The positive energy of group fitness is contagious and I hope to inspire you in the same way I was inspired a few short years ago. I can't wait to see you in my classes and help you achieve your goals!
As a teenager, I was an awkward lank that literally ate everything in sight. To my astonishment, that workhorse of a metabolism I had taken for granted had slowed down to a faint idle in my early 20’s. I decided to take action and got a membership to a gym where I took my first spin class and was immediately hooked. As I began to resemble the “real” me again, I quickly learned that fitness isn’t necessarily about losing weight or gaining muscle; it’s about the way you feel, your strength, power, determination and accomplishments. I started looking forward to my group fitness classes and my mentality shifted from “I have to take that class so I get in shape” to “I can’t wait to have fun in that class and feel great”.

Grateful to now be able to pay it forward as a fitness instructor, I’m excited to pass all that I have gained during my fitness journey on. Whether you’re just starting out or improving what you have already accomplished, remember that there is no set starting point and that you can always dig deeper! Take the step, break a sweat and the rest will follow. You’ll feel great – looking great is just a side effect. Can’t wait to see you at Sonoma Fit!

As a young girl being raised by a single mom in a small town, sports were life. It kept me safe, sane and happy with a body honored for strength and speed over size and stats. In college I played intramural sports to feed my competitive spirit and was lucky enough to land a husband for a softball coach. Fast forward twelve years to a job I love and 2 little girls that constantly move with me. For me movement and fitness provides an outlet, mental and physical strength, and honors the time I have gifted myself as life gets crazy. This love of fitness translates into all my classes; get in and make each moment count! Every rep, each gear added on that uphill battle in spin and that shake you get while holding plank in a TRX strap means you're getting stronger. I like to incorporate a variety of techniques and tools into my fast paced and driving classes; crossfit, barre, boxing, anything that keeps you moving to good music, (preferably EDM and club style, but request line is always open!).
Schwinn Cycling Certified and TRX qualified.
Kyla’s initial introduction to yoga began with Bikram, but started practicing Power Vinyasa Flow Yoga 7 years ago while working as a Helicopter Trauma Flight Nurse.

Feeling the incredible benefits of practicing this type of yoga, she decided to become a yoga instructor and is registered with Yoga Alliance.

Kyla is an active tri-athlete and utilizes a yoga practice to help prevent injuries during training, as well as bring restoration to the physique. Kyla’s love for the outdoors is brought into her yoga classes through strength and balance building routines that utilize the breath to create ease, stability and wellness in the body.

I've been involved in sports and fitness for as long as I can remember. Growing up in Rhode Island, I played soccer, softball, volleyball, and swimming. After I graduated high school, I moved to Arizona for college where I started indoor cycling, running, and became a hiking guide. I moved to Sonoma and began studying for my master's degree in Marriage and Family Counseling at SF State. I now have two children (9 & 11), who are growing up just as active as I did- both are in sports and as a family, we enjoy hiking, biking, and running together. I look forward to helping you meet your fitness goals, whatever they are!

Four years ago fitness became a passion of mine when I decided to compete for a crown, and since then it has become an outlet, an adventure, and a lifestyle.  In 2013, I completed my UC Davis undergraduate degree, and returned to Sonoma in 2017 after graduating from the University of Missouri - Kansas City School of Law.  Throughout law school I competed in Miss Kansas USA and placed in the Top 5 four consecutive years. During competition preparation and law school, my personal exercise routine ranges from group fitness to olympic lifting, but cycling and water-rowing became two primary sources of exercise enjoyment.  There is a huge difference between forcing your workout and enjoying your workout - that is the difference I want to make for people who come to my classes!  I became Schwinn Cycling Instructor certified in July 2017, and look forward to making indoor cycling a permanent part of my fitness journey throughout the course of my legal career.

Danielly originally studied Biology in Brazil. She has been drawn to competitor physical fitness since the age  of 4, this included swimming, volleyball and  long board surfing, but when she came to USA in 2009, her life style changed.  With a sedentary life style, she gained 40lbs and health problems.  “I was tired of looking at  the mirror and not being happy with what I was looking at, so one day I put it in my mind that if I didn’t change now that  I would never change, so I made it a mission to study a lot about nutrition, and exercise and I started  applying it on myself”. After 2 years of self-training and losing more than 40lbs (7 months weight loss), Danielly sought and achieved her certification through NASM, and she specializes in weight loss, strength, balance, and overall well-being. “I really understand the struggles that my clients go through with weight loss because it happened to me, so I am able to help them on this journey”.
