From performing on stage to leading workouts in her gym, Tahiti Hernandez has lived many lives. This article takes a closer look at who she is—her family, her music, her business, and how she’s built a life full of purpose, energy, and love.

Tahiti Hernandez’s Profile Summary

Tahiti’s Early Life in Honolulu

Tahiti Hernandez was born on June 2, 1987, in Honolulu, Hawaii. She grew up in a big, loving family filled with music, dance, and laughter. Her parents, Peter Hernandez and Bernadette San Pedro Bayot, were both performers. Tahiti dad was a percussionist with Jewish and Puerto Rican roots. Her mom was a singer and hula dancer from the Philippines.

As a kid, Tahiti was part of the family band called The Love Notes. Along with her siblings, they performed at local shows and even did jingles for Hawaiian businesses. Music wasn’t just a hobby in their house—it was a way of life. From singing harmonies to dancing hula, Tahiti learned how to entertain from a young age.

Her roots in Hawaii gave her a strong sense of identity. The mix of cultures—Filipino, Puerto Rican, Jewish, and Spanish—shaped how she saw the world.

The Rise of The Lylas

Even though her brother Bruno was becoming a global music star, Tahiti and her sisters decided to take a shot at music too. In 2013, she joined her sisters—Jaime Kailani, Tiara Hernandez, and Presley Hernandez—to form the girl group The Lylas. The name stands for “Love You Like A Sister,” which fit perfectly with their close bond.

The sisters moved to Los Angeles to chase their dream. They filmed a reality show called The Lylas, which aired on WE tv. It followed their move from Hawaii, their music journey, and all the ups and downs of being in a group with family. During filming, something heartbreaking happened—their mother Bernadette passed away suddenly from a brain aneurysm. The show captured that emotional time and showed just how close the family really was.

Despite the loss, the group pushed forward and released songs like “Voices”, which was written by Bruno Mars himself. The Lylas didn’t stay in the spotlight forever, but their time together showed that the Hernandez sisters had their own talent and voice.

Reinventing Herself: From Entertainment to Fitness Leadership

After her time in music and TV, Tahiti Hernandez began a new chapter. She turned her focus to fitness. But she didn’t just become a personal trainer—she built her own brand from the ground up. She founded Uproar Fitness, a gym located on the North Shore of Oahu.

Uproar Fitness is not just a gym. It’s a high-energy space where music and movement come together. Tahiti teaches everything from boxing to circuit training to dance-based workouts. Her most popular class is “Step Fit,” a fun, rhythm-filled workout that brings together cardio and music.

She believes that fitness should be fun, not scary. Her motto is, “If it’s not fun, you’re doin it wrong.” That quote isn’t just on her social media—it’s something she lives by every day. She uses her energy, humor, and passion to make workouts exciting for everyone, no matter their age or size.

Tahiti Hernandez’s Fitness Philosophy and Island Influence

For Tahiti, fitness isn’t just about the body—it’s about the soul too. She uses music, motivation, and even artwork to inspire people. Inside her gym, she displays photos of icons like Marilyn Monroe. She wants women to know they can be strong, beautiful, and powerful all at once.

She often hosts retreats and teaches at major island events. Her work with Sensei Lanai, a luxury wellness retreat, and Common Ground Kauai, a local hub, has brought her message to bigger audiences. She also leads fitness events at Ritz-Carlton Oahu, where she sometimes DJs high-energy dance parties.

Tahiti blends her love of music and movement to create something special. Whether it’s a retreat, a local event, or a group class at her gym, she brings her full self. That includes her Hawaiian heritage, her musical background, and her deep belief in building a strong, supportive community.
