I’ve been training with Coach Xu for more than a year, and it’s been such a rewarding experience!

Highly recommend Coach Xu!

I’ve been training with Jing since March 2025, and it has been such a rewarding experience. She’s not only incredibly knowledgeable and professional, but also truly committed to helping me succeed. It’s clear how much she cares about her clients, and that makes a huge difference. What I really appreciate is how personalized her approach is. Every workout is tailored specifically to me—my goals, my fitness level, and even how I’m feeling that day. It never feels generic. She pays close attention to detail and makes sure I’m using proper form, which helps me train safely and effectively. Jing is always encouraging, never critical, and extremely patient. Her positive energy keeps me motivated, even on days when I’m not at my best. I’ve never felt judged—just supported and inspired to keep going. She’s also very flexible with scheduling, always willing to adjust when life gets busy and do what works best for me whenever possible. That kind of understanding makes it so much easier to stay consistent. Thanks to Jing, I feel stronger, more confident, and genuinely enjoy working out. If you’re looking for a trainer who is supportive, knowledgeable, and truly dedicated to your growth, I highly recommend her.

I've been training with Jing for the past three months, starting with no prior strength training experience, and I couldn't be happier with my results. Jing is an exceptional trainer who is patient, attentive, and genuinely invested in her clients' success. She pays close attention to every detail, ensures proper form, and is fully engaged during every session. I always feel supported and motivated when training with her. What sets Jing apart is her ability to listen and understand my goals and needs. She tailors each workout program specifically to me, making the training both effective and enjoyable. Her nutrition advice has also been valuable and has played a major role in helping me achieve my results.

I’ve really enjoyed working with Jing. She is attentive, knowledgeable, and thoughtful in every session, carefully monitoring my form and adapting workouts to my progress and how I’m feeling that day. I have a frozen shoulder and an old hip injury, and Jing is always mindful of both. She checks in regularly and adjusts the training as needed while still providing challenging, effective workouts. Since I started working with her, I’ve noticed improvements in my strength, stability, and overall fitness. Jing is patient, encouraging, and never overly pushy. Every session feels personalized, and I would definitely recommend her to anyone looking for a supportive and knowledgeable personal trainer.

I’ve been training with Jing Xu for over two years, and I honestly couldn’t recommend her more highly. She has helped me build a sustainable, healthy lifestyle rather than simply following a workout routine. She creates a strong and thoughtful training plan while also incorporating a lot of fun activities, which has made staying active something I genuinely enjoy. Jing is incredibly knowledgeable and is always learning and bringing new ideas into her training. I especially love that she incorporates astrology chart concepts into training—it’s such a fun and unique touch that makes the experience feel very personalized! Beyond being an excellent trainer for people of all fitness levels, Jing is also incredibly supportive, positive, and encouraging. She makes you feel comfortable, motivated, and confident throughout the process. I wholeheartedly recommend Jing to anyone looking for a knowledgeable, supportive, and genuinely fun trainer!

I’ve been training with Jing at Onceinlife Fitness, and I couldn’t be happier with the results. She’s incredibly professional, knowledgeable, and supportive throughout every session. Thanks to her guidance, I’ve made real progress in building muscle and improving my overall fitness. Highly recommend her to anyone looking to reach their goals with a great trainer!

Coach Xu is a highly professional and dedicated fitness trainer. She is incredibly gentle and patient, always taking the time to guide and support you throughout each session. What I appreciate most is how encouraging she is—no matter your level, she makes you feel capable and motivated. Training with her is not only effective but also a truly positive experience.

Jing is a great trainer with professional knowledge for all different kinds of clients. I trained for about a year and felt great with gaining strength and health. I have to leave San Diego for personal reasons, but I hope I can stay longer and learn more about aerial yoga.
