Kelly is a fitness & business professional, author, animal lover, surfer, traveler, and a cheerleader at heart.
Like many, she has struggled in the past with body image and tried various diets, which led to fatigue, frustration, and weight gain. Kelly has faced and overcome her own digestive issues, food sensitivities, and most recently, hormonal, and other physiological changes.
During the pandemic of 2020, when many gyms were forced to close, she searched for a way to stay in shape with little or no equipment. An eternal optimist who always looks for the upside to life's challenges, Kelly saw an opportunity to help not only herself but others, by founding KJ-Fitt.
A driven individual who has overcome health and fitness obstacles in her own life, Kelly now stands ready to extend her experience, research, and training to help you be the best version of you.
Most importantly, she is ready to challenge you, support you, and guide you along that path to a healthier lifestyle!
Kelly is a NASM-certified personal trainer and nutrition coach. She has led an active, adventurous lifestyle, beginning with scholastic & collegiate sports, and working as an aerobics & fitness trainer.
Kelly brings a diverse range of experience to her KJ-Fitt clients, having studied & trained in weight-lifting, group exercise, functional kickboxing, Krav Maga, melee weapons, surfing, and snowboarding.
To ensure the best results for her clients, most KJ-Fitt programs include nutrition coaching and customized workouts. Kelly is great motivator who will help you crush your fitness goals. It must be that cheerleader heart!
Why the extra "T" in KJ-Fitt? Everyone is unique and has their own body styles, so Kelly puts the extra "T" in fit(t), designing the right program for you. Think of it like a favorite T-shirt, some like ‘em loose fit and others like ‘em snug.
Kelly will ensure your program fits you to a “T”!
Come on, let’s do this together! If you will devote just 15 minutes a day, you are on your way to a healthier, more active lifestyle. Kelly's can and will set you up for success by kickstarting an obtainable plan that provides big results.
Every KJ-Fitt consultation includes goal setting, body assessment, weekly check-in’s, and training programs that you can do in the convenience of your home or at your favorite gym. And that’s just the start!


The KJ-FITT 21 Day Double Challenge combines two powerful habits — ditching sugar and walking intentionally — to help you kickstart a healthier, more energized lifestyle that lasts.
This challenge is about more than cutting sugar — it’s about gaining clarity, confidence, and consistency. You’ll learn how sugar may be holding you back from your goals and discover how intentional walking (not just steps on a Fitbit!) can transform your energy, mindset, and metabolism.
Over the next 21 days, you’ll learn, apply, and build habits that stick:
