Working from home meant we could vary snack and coffee breaks, change our desks or view, goof off, drink on the job, even spend the day in pajamas

Many trainers have studied health & fitness to the highest levels, but few to none have lived it and successfully coached it the way I have. Personally, I have lost 115 lbs and achieved 6 pack abs. My top client lost 100lbs of body fat and increased his back squat by 100 lbs in one year! I have a passion for changing lives, mentally, physically and spiritually. It brings me great joy to help my clients grow (or shrink!) into the person they want to be.About me: I am a former Division 1A College Football Player (Offensive Lineman), having played for and graduated from the University of Arizona. I have over 12 years of personal experience in elite-level fitness & athletic training. I have over 5 years of personal training experience, working well with people of all ages, sizes, schedules and goals.My program is completely customized to your preferences & personal goals. With my nutrition program, the food will do about 2/3rds of the work for you! I teach a clean, healthy lifestyle that first transforms your mind, then your body and finally your spirit.If you want to learn more, please contact me (instagram: @coach_kos OR email: coachkostraining@gmail.com).[/vc_column_text][/vc_column][/vc_row]

    Experienced in Seniors and Special Populations.
    - My fitness journey began over 23 years ago in a small training studio in Carmel Valley where I started in the humble front desk position but soon after the owner had me working with some of his clients and also teaching some of the group fitness classes. Still in my final year at UCSD as a Biochem major I thought the job would be temporary until I graduated, but I soon realized I enjoyed working with and helping people more than the thought of working in a laboratory environment.I became certified through the National Strength and Conditioning Association as a Strength and Conditioning Specialist and also, within the last few years, obtained my Special Populations Certification focusing on working with seniors, people with chronic illness, as well as stroke and brain injury. My present endeavor is completing my second level of Egoscue training after completing my first earlier this year focusing on postural assessments and therapy to help my clients live a pain free lifestyle.What has kept me in the fitness industry as long as I have been in it is the connections I have made with my clients and the intrinsic reward of knowing that I am a positive reinforcement to their health and well-being.[/vc_column_text][/vc_column][/vc_row]

My journey began during high school when I embarked on a weightlifting regimen to conquer my own struggles with excess weight, cardiovascular limitations, and a profound dissatisfaction with my appearance. Through hard work and perseverance, I not only shed pounds but also unearthed newfound confidence and boundless energy that transformed my entire outlook.Having experienced the profound impact of fitness firsthand, I've made it my mission to share this life-altering potential with the world. I empathize with those navigating similar challenges, and I'm committed to helping them reclaim their lives and discover the same positive vitality that propelled me forward.To fortify my knowledge and expertise, I delved into the intricate workings of the human body. This led me to pursue a rigorous education in biology, culminating in a Bachelor of Science degree from Oakland University in Rochester, MI. Driven by an insatiable thirst for understanding, I subsequently earned my Master of Science in exercise science at the same institution. My dedication to excellence is exemplified by my certifications, including personal training, performance enhancement, corrective exercise specialization, and MMA conditioning from the esteemed National Academy of Sports Medicine (NASM).My professional journey has been further enriched by hands-on experience working with diverse clients grappling with various ailments, ranging from herniated discs to hip and knee replacements, even heart failure. My expertise extends to three main focal points: weight loss, bodybuilding, and powerlifting. Crafting tailored exercise programs is my hallmark, a personalized approach where I meticulously tailor each regimen to suit the unique needs and aspirations of every individual under my guidance.In my role as a Personal Trainer, I'm not just a fitness instructor, but a steadfast ally in the transformative journey towards a healthier and more fulfilling life. My passion, honed skills, and empathetic approach converge to empower my clients, helping them overcome obstacles, exceed their goals, and embrace the boundless benefits of embracing fitness. Together, we embark on a path of self-discovery, resilience, and unwavering commitment to personal well-being.With every client, I forge a partnership grounded in understanding and trust, enabling us to navigate challenges together and celebrate triumphs as a team. I firmly believe that physical well-being is a cornerstone of a joyful life, and I'm dedicated to instilling that belief in each individual I have the privilege to guide. Through personalized attention, unwavering encouragement, and a wealth of scientific knowledge, I'm committed to making a profound impact on lives, one transformative workout at a time.[/vc_column_text][/vc_column][/vc_row]
