ABOUT US

History

Built by Experience. Backed by Purpose.

JaniferSmithFitness was born from Janifer’s personal journey—from feeling burnt out and stuck to discovering strength through simple, sustainable fitness. What began as her own transformation turned into a mission to help other women do the same.

Since 2016, we've empowered thousands of women to build confidence, strength, and balance—without extreme workouts or diets. Today, Janifer Smith Fitness is a trusted space for real women ready to take control of their health, one step at a time.

You’re not trying to become someone else—you’re becoming your best self."
