His methods, which have been forged over 20 years of personal training experience, are tried, trusted, and results driven.

No project is too big or too small for Scott and his SYP Trainers to take on. They can handle all the specific physical needs of any actor, group of actors, touring musicians, and models for any production or project in Los Angeles, across the nation, or internationally.

5 Reasons why Entertainment Professionals trust us

  • Full discretion – Even though Scott is regularly seen on media outlets as a ‘Personal Training Guru’ and an ‘A-list Performance Coach’, we at SY Performance never share our client list with the media without their discretion. Scott Yonehiro is well-known in the fitness industry & constantly appears in the press, but any and all ‘celebrity’ media attention we’ve been mentioned in starts from our celebrity clients and never from us first. We don’t talk about our high profile clientele to the press or social media…ever.
  • A track record of success – Scott has physically prepared the lead and supporting Actors and Actresses in numerous high profile films, Television series, and theatre projects.
  • Aesthetic Training – As the recommended trainer to entertainment professionals in Hollywood, Scott has helped many Actors build muscle size, slim down and drastically lose weight safely, and sculpt their body to precise character role requirements. Scott has a proven track record of working with Directors and Producers to create the perfect body for any character that any actor may be portraying. We will help you achieve that quickly, safely, and in time for the cameras to roll.
  • Character Movement & Injury prevention – Scott has helped numerous Athletes, Stuntmen, Dancers, and MMA fighters move more efficiently and with better direction. In doing so, Scott has built a regimen to assist non-athletic Actors to move better and prepare for complex stunt work or challenging physical roles. This in turn reduces the chance of injury during both pre-production and production for the actor.
  • Martial Arts Training – Scott was born and raised in Hawai’i and fed on a steady diet of martial arts training and real life street fighting. Scott himself has several years of training in the principles of Boxing, Akido, Kali & Escrima (Filipino stick & knife fighting) and has helped actors prepare for roles requiring this knowledge. He and his team understand martial arts and combat and can teach you real fighting skills to help with your fight choreography (or to help you get into character.) We can also bring in additional experts in Muay Thai, Krav Maga, Boxing, Kung Fu, and BJJ, when necessary. We have experience in teaching fighting skills to lead characters and are used to working in unity with stunt teams.

“I reached out to Scott while prepping for a specific role where I had to look and move like a triathlete. Now, I’ve been exercising and working out for the majority of my life but to look and feel like I’d be able to believably complete a triathlon was beyond my knowledge. Scott sat me down and assured me that as long as I followed his instructions wholly he’d be able to get me there. Sure enough, I got there. It was the best shape I had ever been in in my life. Since that role I’ve gotten to play many different characters with different body types and Scott got me to where I needed to be. Even through certain nagging injuries, he has been able to work around them, keeping me in fighting shape. But to say that he strengthens you only on a superficial level would be shortchanging his actual gift. He is a master at training your mind, to put mind into muscle and to rewire your understanding of pain. Training with him gave me the mental fortitude to attack workouts with the intention to welcome and then overcome pain all while maintaining proper form- which for those who workout regularly may be the hardest part. I know I can get sloppy as anyone come rep number 11.”

“Scott approaches fitness and coaching from an incredibly unique angle that makes him an absolute treasure, in my opinion. Not only does he bring a wealth of knowledge and years of firsthand experience to the table but he focuses on empowering his clients to become the best versions of themselves. His approach is one of self-empowerment and discovering your own drive to mold yourself into whatever it is you wish to be. It’s a far more powerful motivator than simply pushing you to work out harder (although he does that too, when needed) and something you can carry with you into any other area of your life. Scott combines a deep understanding of how to transform one’s physique with an even deeper understanding of what inspires people to stick with that transformational process and build that into an approach for…well, everything. You can find plenty of trainers who will make you do that extra set of pull ups. Scott helps YOU demand that from yourself. Thanks for everything Scott!”

Noel Fisher, Actor, best known for his role as Mickey Milkovich on the Showtime series ‘Shameless’, as well as his portrayal of Cael Malloy on the FX series ‘The Riches’, and Vladimir a Romanian vampire in the final chapter of the ‘Twilight’ saga.

“Scott Yonehiro is truly a special trainer. As an actor, your body is part of your calling card and after having my second child, I wanted to reshape my body into the best version that it could be. Scott is beloved in the actor community for his understanding of the business, his respect for privacy and his focus on professionalism. More importantly, it is very rare for a trainer of his caliber in the entertainment industry to possess the level of humility and kindness that he has but Scott is that trainer- you actually want to be around him. He embraces you for who you are wholly and is able to take your body to its optimum level of performance, yielding results that I didn’t know were possible. With great compassion and a steady approach, he has now gotten me camera-ready by pushing me towards my goals while keeping my lifestyle in mind. He not only trains your body but does so while prioritizing your mental health. A stabilizing force, Scott continues to motivate me to reach higher potentials for my mind, body and soul.”

Charlet Chung, Actor, best known for her role as Julia Argent in the series, ‘Carmen Sandiego’, and as Margaret ‘Echo” Pearl in the hit series, ‘Fast & Furious Spy

“I came to Scott YONEHIRO because I was hurt. I’d had trainers in the past that were, nice guys. But not people I would trust again with my physical health. I have a slipped disc in my L5S1, ribs that were quickly popping out of place. Shoulders and other joints that weren’t reliable. I felt like my own body was betraying me and I was just trying to reconnect with it. With myself. When Scott and I first started training I could barely use anything more than bands. And then the pandemic hit and my time working with him was one of the few things keeping me sane. There are people who are certified as trainers. And then there are Trainers that are so knowledgeable that they can lovingly help guide you back from injury, to who you really are in your body. I feel strong again. And I owe so much of that to Scott. He’s become a brother to me and I can’t fully put into words how grateful I am for him.”

E.J. BonillaE.J. Bonilla, Actor, best known for his role as agent Raymond Waters on the FX series ‘The Old Man’, and as Lt. Shane Aguero on the hit mini-series about our American forces in Iraq, ‘The Long Road Home’.

“A few years ago I had an accident and broke my shoulder. I was unable to exercise for six long months. I had wreaked so much havoc on my body that I had gained weight, and I both looked and felt terrible. A friend highly recommended Scott Yonehiro and SY Performance so I decide to give him a call. From the moment I met Scott I felt at ease. He was extremely knowledgeable and knew exactly what steps he would take to help me get my body back. I knew Scott could help me and there was no way on God’s Green Earth that I wasn’t going to train with him. In 90 days he took me from wearing double spanks to a bikini! I kid you not, I actually wore a bikini on a trip to Jamaica! That NEVER woud have happened without Scott’s help.”

Wendy DavisWendy Davis, Actor best known for her role as Joan on the hit NBC series, ‘Bel-Air’, and as Colonel Joan Burton in the hit Lifetime series, ‘Army Wives’.

“I was incredibly lucky to find Scott when I did. I was hired to work on a show where I would be playing a personal trainer and I needed to get in personal trainer shape fast. After a year and a half of a pandemic and not working out as much, I was really worried I wouldn’t get there in time. But Scott knew exactly what needed to be done. He gave me a very specific and detailed meal plan and workout regimen that made the whole process so easy. He even corrected some form issues I didn’t even realize I had. He’s hands down the most knowledgeable and experienced trainer I’ve ever worked with.”

JT NealJ.T. Neal, Actor, best known for his role as the loveable personal trainer Matt on the hit FOX series ‘Pivoting’, as well as Jacob on the series ‘Bless This Mess’.


“I had to gain about 20 lbs of mostly muscle in only 2 weeks given time by the film studio and right at that moment I injured my lower back which severely limited my movement. Before finally going to Scott I had already gained about 13 pounds but 90 percent of it was fat around my midsection and was not properly distributed throughout the body. Finally going to and working with Scott was instrumental in getting me to my final end goal and balancing out the look of my body with proper proportions. Not only did he provide a strict workout schedule but Scott gave me that extra push during the intense workouts to get me over the hump. Scott was super personal, caring, and I was extremely happy by the fact that by the deadline when I started filming I had surpassed the studio’s request and jumped up over 25 lbs in only 2 weeks! Everything I did prescribed by Scott was all natural and no anabolic steroids were used. I can’t tell you how many people thought I “shot up” and used steroids to get to my ending goal. An extremely huge thanks to Scott Yonehiro and to also the amazing personal environment to train in that SY Performance provided.”

“Whether you want an in-depth cross style workout or just want to improve your flexibility, Scott will customize a workout that fits your needs, goals, and lifestyle. He’s got a bag of “tricks” that will work several body parts at once for those days you’re short on time, as well as longer, in-depth workouts for a more focused training day when your schedule permits. Best of all, he does it with encouragement, support, and a smile on his face.”

Indra Peterson Indra Peterson, CNN Meteorologist & News Correspondent


“As a professional actor, it is of the utmost importance that I am always audition-ready, and both look and feel my best. Scott Yonehiro is the answer to all of these needs. Scott listens to what I’m trying to accomplish with my body for a particular role, and creates a fitness routine and diet to get me there. Even when I’m filming out of town, he’s hooked me up with a full workout schedule (including demo videos to ensure proper form) and a meal plan for me to follow until I get back. He’s constantly going above and beyond to help me reach my goals. Being one of the friendliest, and down-to-earth trainers you’ll ever meet, Scott not only constantly challenges me, but he makes the process a whole lot more fun too.”
