Jonathan Gill - Director and Program Designer
Jonathan Gill, founder of Gill’s Fitness, was born in 1972 in Oakland, California. Early in his life an obsession with fitness and athleticism grew in tandem with his dedication to soccer and martial arts and by 1988 while still in high school Jonathan was strength training daily and a diligent student of anatomy and biomechanics, applying what he learned not just to workouts for himself but also for friends and fellow athletes.
In 1990, Jonathan moved to San Diego to attend San Diego State University while continuing the development of his own strength training methodology. One year later, in 1991 while still attending SDSU, Jonathan began providing personal training services in San Diego applying his unique approach with his first clients coming from those asking him for assistance and advice when seeing him working out in local gyms.
In 1992, Jonathan was recruited by a large gym chain’s personal training division and spent the next year teaching his methodology to trainers and clients throughout San Diego county all the while continuing to build his own clientele and pursue his goal of creating the safest, most effective system of strength training ever designed.
By 1995 the popularity of Jonathan’s personal training services had grown such that he decided to open a private gym from where he could conduct his personal training programs, and hire and train trainers to serve his growing clientele. In 1997, writers from various news outlets in San Diego heard of the success of the many clients now enjoying the rewards of Jonathan’s programs. During the next few years Gill’s Fitness would appear 14 times in San Diego publications featuring dozens of success stories ranging from adults recovering from histories of injuries or disabilities to grandparents and retirees looking to better enjoy grandchildren and their golf games.
In 2020 Jonathan celebrates 28 years training with one of his founding members and more than 20 years with 14 others, with dozens more not far behind. Gill’s Fitness remains one of San Diego’s most successful and well established personal training businesses with an unmatched track record and more than a hundred testimonials proudly and confidently recommending it as one of the best decisions a person can make to improve quality of life.
