A message from CK Kellum - founder of BUILT Fitness™


If you’re ready to maximize the moment — better yet, if you’re ready to become healthier and stronger so you can maximize ALL the moments of your life - you’ve come to the right place.


I’m a nationally-certified fitness instructor, nutritional advisor, motivational speaker and former NCAA track champion. I've been training individuals, groups and teams for over 15 years, helping my clients to lose weight, tone up, build strength, prepare for competition, and live much healthier lives!


BUILT launched in 2014 and I’m proud to say we're one of the fastest-growing fitness businesses in the mid-Atlantic. My team and I serve over 100 great clients in both Philadelphia and King of Prussia, Pennsylvania. And though we're growing fast, we're always looking for motivated new personal training clients, and new members for our fast-paced, dynamic group and team training classes.


We work with people at all ability levels, from those who are just starting out with exercise to those who have extensive prior training and sports experience, and our clients include people from all walks of life - corporate executives, working professionals, and high school, college and professional athletes. I also personally work with a number of elite high school and college athletes, providing them with the intensive and specialized one-on-one training they need to prepare for their recruitment and draft journeys.


I hold a number of respected national training certifications, and have many years of experience putting them to work in everyday practice. I'm personable, smart, fun and outgoing. No matter who you are, my team and I will listen to your needs and goals, and help you get where you want to be one step at a time. I have a deep background in coaching, so I'll be able to help you make those behavioral and technical changes you need to get you to your goals.
