I was originally using an extremely overpriced personal trainer at a 24 Hour Fitness Gym to get ready for my wedding which was only 8 weeks away. I knew there had to be a personal trainer in Orange County out there who didn't charge the ridiculous price of the 24 Hour Fitness Gym and was just as effective if not better. I was referred to Jackie Nguyen and decided to hire him as a personal trainer. Jackie's training program was amazing with the combined strength training, core exercises, circuit training, cardio exercise, meal plans, and nutritional counseling to help maximize my results. I went from weighing 215 pounds down to 197 pounds! Seriously amazing results. I think the last time I weighed that much was before college. I got a lot of comments about my weight loss and how great I looked from friends and family at the wedding. All in all, I was extremely happy with the results and my wife also thought I looked great. :) I would highly recommend Jackie to anyone who is looking for an educated and certified personal trainer at an affordable price. Thank you Jackie! -

Before I retained a trainer, I did my research and met with various trainers. Jackie definitely knows his stuff. He combines various techniques such as strength training, cardio

training, circuit training, core exercise, abs work out, boxing, and kickboxing. And resistance training as well so that your body isn't getting use to it and is always working to reach your goals. If you have a certain goal, Jackie will help you attain it. Most people are talking about losing weight but I was one that wanted to bulk up. In the past few months working out with Jackie, I can see a big difference. The way he combines your work-outs and the meal plan is geared towards my goals and help me always stay energized for the remainder of the day.
-Majid H






I've trained with quite a handful of trainers, and I never felt I got my moneys worth till I started training with Jackie Nguyen. If you're not motivated to work out, or not comfortable working out with a trainer, or if you feel it is impossible to eat healthy... then try Jackie out, he'll definitely fix you up :)

His flexible schedule, positive attitude, and above all his genuine commitment to his clients fitness goals is what makes him a great trainer!

His professionalism, extensive knowledge and enthusiastic commitment to his work and ultimately his clients, provides the perfect scenario for success and sets the foundation for a new healthier lifestyle.

I have always really struggled with exercising. While I know that it is a critical part of being a healthy black woman, I never seem to find the time or motivation to get or stay in shape. Jackie has helped me to break through the frustrating cycles of excuses that I create for myself. He has trained me without a Drill Sergeant approach, any other way would have made me give up! Jackie enthusiasm is great and his knowledge of fitness is such an encouragement! Jackie's support and passion have enabled me to have more energy and a much toner body and ENJOY the result of exercising!

-Sherice G.





Jackie also helped me achieve an amazing six-pack with an intense work out that utilizes much more than just simple crunches. He not only taught me new exercise, but also helped to work in the perfect amount cardio to really see results.

Thank you Jackie I know what I am supposed to do in the gym and don’t just stand around like a goof or overwork my muscles with repetitive exercises. He is incredibly professional and always encouraging. He asks for effort, and if you let him work his magic, I guaranteed you will see amazing results. Jackie is simply the best; I owe him a lot!"

-Chandler M.








I was 28, fat and flabby. I've lost 30 pounds of FAT so far and feel great! I have much more energy now. Jackie's workouts are effective and efficient. I failed to feel the burn. Jackie is incredibly skilled and talented in his trade. He knew just how to make sure that I was working hard enough toward my goal. Jackie is very motivating. He keeps it interesting. I wouldn't still be doing this without him. I'm cheap, but I'm definitely getting my money's worth. I can't see myself working out alone anymore because I would be wasting my time. Jackie gave me results in just three short months.






Jackie has done an extraordinary job helping to get me in shape. He is knowledgeable, encouraging, and full of energy so that every time I see him I have a far better workout than I could on my own. Before seeking a trainer, I read up on fitness, and Jackie's approaches harmonize with the best of what I have read. I have no doubt that he will help me to achieve my fitness goals and feel great about it--I've already got a solid start. I lost over 10 POUNDS in 1 months of training with Jackie, and my body fat went down as well.

-Chris Martin





I thought I had good endurance, but my 1st week of training with Jackie proved me wrong. Thanks to Jackie's workout I have more energy and feel better. I was able to see a difference within the first week. I would recommend him to anybody who would want to improve their physical and mental attributes.

-Everlyn L.





If you are like me and working out a little, and wondering what benefit a personal trainer would make, Well I'm here to tell you that working with Jackie has far exceeded my expectations. In two months the Results are dramatic, and in a number of areas.


As a middle aged man, It didn't expect to see much change in my physical appearance, but I have. I've been on weight loss programs before, and never lost more than 2 lbs/month. With Jackie I'm eating just the same healthy way as before, but I'm losing at the rate of 8 lbs/ month. Big difference. And I feel stronger in my core. By myself I would workout the easy parts of the body, but with Jackie, now we get to it all.

-Bob Henderson ( 52, Male, 5' 10" , now 179 lbs, & 32 inch waist)







I have had several personal trainers over the years, but Jackie is the by far the best. I've been with him for about 10 weeks and he's constantly varying our workouts so I never get bored. He pushes me when I need a pushed, but always keeps things fun and interesting. I'm following his comprehensive meal plan and lost 9 lbs in two weeks!  Thanks again Jackie.

Jackie is by far the most effective trainer I've had. Work out sessions with him is not only just pumping weights, there's cardio kickboxing, circuit training...it just makes things more fun even though it's still tough. I absolutely love the meal plans and times, I don't starve anymore and actually don't feel bad for not eating "sinful" foods! My body is alot more lean and I feel healthy without trying too hard. Give him a try! Thanks Jackie!!










Before I found Jackie, I never exercise and was completely out of shape. Since I have started with him, he has me totally addicted to the gym and working out. I am much leaner and feel so much better about myself and have a lot more energy. He keeps me motivated and I plan on sticking with him long after I reach my personal goals.

-Lindsey Lockshaw





In my opinion, Jackie is the best trainer I have had. His method of designing a program precisely to meet my fitness needs is absolutely perfect. I have been an athlete all my life and worked out all my life. Now, I have a whole new approach to working out and fitness goals.







Jackie combines a fun approach, using kick boxing and martial arts along with a perfectly designed work out to strengthen my body and in my case lose weight. I enjoy going to my appointments and when I leave, I know I have accomplished something. One last part of his training approach, he helps design a nutritional program also to meet my goals for which foods I should be eating, I rate him an A+.

-Jim Kennedy





Jackie is a very good personal trainer. He is always encouraging and has a way of always make me go the extra mile during my workouts. I don't think I've ever felt my whole body so sore after 2 workouts, which means I'm getting in shape the right way.

- Nathan Liao


Jackie has made a huge impact on my journey toward a healthy lifestyle. Not only has he been my own motivational speaker, but his expectations for my own success push me to the very limits I never knew I could achieve.

-Jessica McLaughlin





When I started with Jackie, I was totally out of shape, I could barely finish 10 push-ups and do curls with 10 lbs weights. After 2 months, I lost 5% of body fat and replaced it by muscle, I consider push-ups to be a warm up and I do curls with 35 lbs weights! Jackie is also great to recommend supplements and to give diet advices.

-Daniel Pageau


Jackie is a great trainer! He cares about his client's overall health and fitness and gives 110%. He is also honest, fun and flexible which is hard to find in a trainer these days.
