About Yellow Brick Fitness

Our Mission is to build hybrid athletes and human athletes with character.

Yellow Brick Fitness is a brand new class-based gym, located off US-31 W where White House, Millersville, and Goodlettsville meet. Our community-based atmosphere is a place where people of all backgrounds can come together to become physically, mentally, and socially stronger. We hold daily group strength & conditioning classes (think CrossFit meets HIIT), led by owner and lead trainer Jeff Caldwell. Jeff’s years of experience and unique training background makes these classes second to none, allowing everyone to get the most out of each workout, no matter their fitness level. We also offer private personal training, and sport-specific athletic training for athletes of all ages. We currently have basketball and baseball training specialists available. Every membership includes access to our chromotherapy infrared sauna, and cold tub. We also have individual and team rentals available for the batting cage/pitching machine.
