About Jennifer Lieb

Training with me is about more than just changing your outer appearance. I aim to help my clients become healthier, happier, and create a lifestyle change that is sustainable. I accept clients of all athletic levels and specialize in fat loss, muscle building, and postpartum fitness. The gym can be a daunting place and it is my goal to ensure my clients receive the best workout they can while feeling comfortable. I look forward to working with you!

Check out my Instagram for more pics/videos @Jenniferlieb_ I *only* train out of Reign Training Facility in Corona. Please keep this location factor in mind when scheduling a consultation. Thank you for your preference!

Jen was my trainer for over a year and I can’t thank her enough for the amount of knowledge, patience and dedication she put into helping me reach my fitness goals. My main goal was to build muscle and we did just that! She taught me progressive overload, correct form and proper nutrition. I have gained so much more confidence in myself and feel stronger both physically and mentally. I highly recommend Jen as a personal trainer!

I worked with Jennifer in December 2024 and she was AMAZING. She was great at communicating when there were changes in the schedule. I grew so much for confident in the gym and making meals that help me hit my goals because of her. I highly recommend working with her and making the investment!

I’ve been training with Jenn for the past 4 months and she has been nothing short of amazing. She is a true professional. During the initial consultation, she took the time to listen and understand my goals. I was recovering from an ankle injury and she incorporated exercises that have helped strengthen and re-stabilize my ankle. The thing I appreciate most about her is how attentive she is. Throughout every session she is completely focused on you- ensuring your form is correct and you’re getting the most out of each exercise. So far I’ve gained muscle mass and simultaneously lost about 9-10 inches overall. I would 100% recommend her to anyone who’s serious about getting in shape!

Where to begin!! I have been training with Jen for 7 months now and I would say easily that she is the best person I have trained with by far- and I have had my fair share of experience working with trainers! I really wanted to get stronger, more confident, and establish a routine of fitness again after Covid threw me off. She has helped me do so while taking into account my sciatic limitations and working around those limitations than pushing me through them to the point of a flare up. She is not one to cancel sessions often and is super timely+communicative. I am so beyond appreciate of her kindness, patience, and knowledge about gains. I actually wore shorts IN PUBLIC for the first time in YEARS today because of her. She’s the best so don’t wait and just get started lol.
