About
I’Ready to train? I’ve been a personal trainer for over a decade and have worked with all types of clients from those with injuries to building strength. I have a degree in Kinesiology with a focus on Exercise Science at Cal State Monterey Bay in 2011.
I started as an assistant soccer coach and strength condition coach at Skyline community college for both Men’s and Women’s soccer programs. I have also worked as a Fitness Director and Manager for multiple gyms.
I build tailored program layouts for all types of clients. I specialize in weight loss, muscle building, rehabilitation, athletes, cardio, and functional training. I became a trainer to change people's lives. Giving people a chance to live healthier and move better. It's what I live for.

If I could give 6 stars, I would. Will has been nothing short of exceptional - a trusted advisor not only to me, but to my entire family when it comes to health and wellness.
His thoughtful, historically grounded approach goes far beyond surface-level fitness. He has had a substantial impact on my health metrics - from blood work and body composition to weight, muscle mass, and VO₂ max. I’ve seen real, measurable improvements across the board.
He’s not just a trainer - he’s a strategic partner in helping you reach your best, healthiest self. Couldn’t recommend him more highly.

William is extremely professional and an attentive trainer. He helped me build muscle and navigate my different mobility issues from previous injuries via recovery exercises. He is extremely patient and digs deep to find the root cause for any issues and quickly adapts his workouts. I also got to learn a lot more about Bay area history and politics from him. I would highly recommend him as a trainer.

I have been working out for decades with fitness trainers so have some experience of the good, bad, and ugly. Will is none of these: he firmly occupies the GREAT category. He just radiates competency about all aspects of goal oriented fitness, including building muscle, losing weight, injury recovery and prevention -- he has done all of these for me. Beyond that he has superb knowledge of nutrition, flexibility, and holistic good health. He is methodical, careful, the only trainer I have met who keeps detailed notes, and constantly probes for any questions so that he can transfer competency to his clients. He takes client goals seriously and aggressively without engendering any risk. So, yeah, here is the very top of the top of fitness trainers that I have ever experienced in terms of knowing exactly what he's doing and getting you exactly what you want. But that's only part of why I'd rate him as GREAT. The other half is Will's character. He is kind and empathetic, has an absolute service mentality with his own highest standards, is of total personal and professional integrity and decency, is hyper responsible, and is a passionate, fun, open guy to be around. My wife has a highest standard for people: good human (haven't make the grade yet myself...). Will Sandoval is a good human. Extraordinarily competent and committed, brings his own deep values to what he does, and truly cares for his clients. This guy is a rare treasure, amongst trainers and amongst people. My life is better (and longer) because of him. I recommend him to you unconditionally and without any hesitation whatsoever.

Willis is absolutely a gem!. I have been working out with Willis for 1 1/2 years and it has been a real pleasure. He really sets up a program geared towards your exact goals. I strongly recommend his service if you want a terrific personaltrainer.
