Jeffrey Yu Fitness - San Francisco, California

Amy Davis

I have been training with Jeffrey for 2+ years now so this review is long overdue! Jeffrey knows a ton about exercise and nutrition and he really tailors his workouts to each individual with their specific goals in mind. I have seen a lot of trainers who apply a blanket approach to their clients' workouts (just sort of going through the motions) - not really considering that each individual has varying physical abilities, drive and goals. One size does not fit all when it comes to health and fitness and Jeffrey really understands and applies this concept. He also adjusts our workouts as my fitness goals change.

He is knowledgeable, patient, attentive, consistent and also a really nice person.

Jeffrey Yu is fantastic as a personal trainer, and I have worked with several over the years. By way of a great review, check out my first review from three years ago, below.

Over the last three and a half years, he has been 100% supportive and has moved me further and further along in my fitness. During periods when I was not in top form, he adjusted the workouts to suit the situation and we rebuilt my strength, endurance, and flexibility.

His reliable knowledge, skill, and enthusiasm are a perfect fit for anyone looking to improve their fitness.

Very highly recommended.

I have worked with great personal trainers before and Jeffrey Yu is top notch. He is tremendously knowledgeable and professional.

You will need to put in the work and follow his recommendations. The result are completely worth the effort. I am nearly 50 years old and am thrilled with how my health has improved.

In 5 months I have lost 15 pounds and 3 inches off my waist. I am stronger and running better than I have in the last four years. Just ran my first 5k this last weekend and I am on track to meet or beat the Military Army Physical Fitness Standards next month. Not visible, but probably the most valuable change is that my resting heart rate is 10 beats a minute slower than when I began working out with Jeffrey. A slower resting heart rate is a measure of good fitness and protective against future cardiovascular disease. (Individual's mileage may vary, of course.)

I highly recommend Jeffrey Yu to everyone who is interested and easy to take care of their physical fitness.

I have been working with Jeffrey for 4 years now. He has a big impact on my health and fitness. I lost 15 pounds and feel great about my energy level and look. He is a very professional and experienced trainer, a person you can trust and be friends with. Most importantly, he cares about his work and clients deeply. I feel very lucky to have him help me to keep my fit and healthy.

Jeffrey Yu is an excellent trainer! I am a mom in my 40's and just started getting back in shape. I was never a gym type of girl and definitely not a lifting weights type but Jeffrey's knowledge and expertise are outstanding. He is very good at explaining, emphasizing good form. He created a very thoughtful training plan to help with my goals. Great results! I highly recommend him!

I have been working with Jeffrey for 5 years -- he is truly an exceptional trainer. I have worked with a lot of trainers and can unequivocally state that he is the "best of the best". He keeps fastidious notes. He encourages me constantly. He can switch gears if I have a compromised knee or shoulder. He helps me to troubleshoot when I have an ache or a pain to figure out how to alleviate it or prevent it from reoccurring. He is an excellent listener and observer. He switches up the sessions so they remain engaging and interesting. He texts me encouragement. As a result of his work I have a body that is strong, stable and looks good! I continue to celebrate our relationship with great respect and fondness. I highly recommend Jeffrey and live in gratitude to have been guided to him.

Jeff has seriously changed my life. He has shown be the way when it comes to how weight training and finding the right fitness balance in my life. I work out with Jeff 2/3 times a week and every session I learn something new. I’ve had a number of trainers and Jeff is as good as it gets. I can’t speak higher of a trainer! He makes every session fun and challenging.

Jeff is also the coolest dude and I truly love spending time with him which makes every session go by real fast! Couldn’t recommend a trainer more than Jeff. Seriously. Do it!

Jeffrey is an awesome fitness trainer that i got to know and work with through a friend. He will work as per your schedule and with you to meet your fitness goals. He also checks on you and your nutrition through the process which not all trainers do.The best part is the price is very reasonable and you can make payment plans as you go. Most trainers in the city from my experience make you pay the total amount up front. So if you looking and motivated to attain your fitness goals Jeffery is tge person to go!!

Jeffrey is a very creative and thoughtful; trainer. I hadn't worked out in 40+ years and came to Jeff after reading great reviews about him. He understood that I needed to start slow and rebuild muscles that I hadn't used (or knew existed) for decades. It has been 10 months now and we've worked our way up to a good workout. I'm stronger, have lost weight and am seeing a change in my body shape. He not only works on the body but is a bit bossy about my diet and aerobic regimen. He texts me regularly top ask how I'm feeling and seems to take a real interest in my well being. He has an easygoing manner and isn't a drill sergeant at the gym, which I appreciate. If you have been meaning to get back in shape, see Jeff!
