Bodybuilding
for Babies 

Who says toddlers can’t understand muscular anatomy? Forget "arm" and "leg"— it’s time for your little lifter to identify their lats from their quads!

Bodybuilding for Babies is the first book in a high-energy movement series designed to inspire physical literacy from day one. Created by a fitness professional and a whimsical illustrator, this board book turns muscle-learning into a playful game of discovery.

Inside this fun and inviting world, you’ll find:

  • 10 Major Muscles: Introduce your child to the language of movement with anatomically correct names and their casual counterparts.

  • Professional Poses: Featuring traditional bodybuilding and physique poses that make for the most adorable "move-along" reading sessions.

  • A "Hide-and-Seek" Adventure: Keep little hands busy and eyes sharp as they search for the hidden apple on every page!

  • Vibrant Illustrations: Hand-drawn by Maryna Polonska, every page is packed with warmth, personality, and colors that pop.

  • Expertly Written: Concept design by Jackelyn Ho, a long-term certified trainer and fitness instructor, the book is formatted to engage and encourage learning with your little ones.

Whether you’re a fitness enthusiast looking for the perfect gift for new parents or you're a parent yourself wanting to foster a strong foundation for your child, this book is the ultimate starter kit for a lifetime of movement.

JACKELYN HO

Jackelyn is a certified trainer and yoga instructor who has spent nearly two decades empowering her students through sweaty workouts. After years of focusing on human movement and anatomy, she wanted her daughter to be familiar with more than just “arm” and “leg,” envisioning a world where toddlers knew their lats from their quads. This playful quest for anatomical accuracy sparked the creation of Bodybuilding for Babies, a series designed to help tiny humans celebrate their big strength from day one.
