Melissa Peralta

Founder

Melissa Peralta was born in the Dominican Republic and moved to New York at the age of 13, a transition that shaped her identity and resilience. She pursued her studies in business and built a career in healthcare, where she learned the importance of compassion, discipline, and caring for others. In 2019, Melissa discovered her true passion: Fitness. What began as a personal journey quickly became a calling, inspiring her to guide others toward healthier, more confident versions of themselves.

As she grew into adulthood, Melissa realized that many traditional habits from her upbringing weren’t aligned with long-term health. Determined to break generational patterns, she committed to building a lifestyle rooted in balance, strength, and self-care. This transformation wasn’t only physical, it was emotional and mental. Her journey taught her that change is possible at any stage of life, and that discipline becomes a form of self love. Her own results became her greatest motivation to help others begin their journey, no matter their starting point.

Today, Melissa’s work continues to create an impact within her community. People see in her a living example of what dedication can look like, and her growing following reflects the trust she has built. Through her programs, guidance, and authentic transparency, Melissa empowers others to adopt healthier habits, rewrite their stories, and pass these lessons to future generations. Her mission is simple but powerful: to help others transform their lives from the inside out, just as she did.
