Personal Trainer

Jenni Davidson

Personal Trainer

O'Fallon

I am a NASM Certified Personal Trainer and NASM certified Physique and Bodybuilding Coach. I also am an ACE certified Strength and Conditioning Coach and ACE certified Group Fitness Trainer.


I am a mother of 3 amazing humans and dog mom to a beautiful Doberman.

I have over 2 decades of experience in the fitness industry. My training philosophies are rooted in functional training principles, emphasizing movement patterns that translate into real-life activities. I firmly believe in the transformative power of strength training, particularly for women as they navigate through different stages of life. I am passionate about introducing youth to the gym. Making fitness fun while teaching proper form and execution of movement is the key to injury prevention, especially among young athletes.


I trained at Integrity for several years as a client prior to joining their incredible team. I had a goal to compete as a natural bodybuilder and was guided with personal training and a nutrition plan that not only helped me achieve my goal of stepping on stage, but also helped me to earn my Pro Card. I consider myself blessed to have a job I not only love, but one that allows me to witness transformations everyday. It is a privilege to be a part of each client’s journey!
