She’s an enthusiastic leader whose focus is creating a space where you can show up as you are and get stronger in every way. And she leads by example—there’s always a race she’s training for!
TRINITY ALVIDREZ has always found joy in movement—from dance classes and 5Ks to hiking any trail she could find. In 2019 after back-to-back pregnancies, her approach shifted from fitness as fun to fitness with purpose. Fueled by inspiring instructors, Trinity dove into becoming a coach/trainer. She discovered HYROX via Erica, was instantly hooked, competed in her first HYROX in 2023 and hasn’t looked back!
Today, you’ll find Trinity strength training, crushing hybrid workouts, and leading classes at CABRA. She’s a HYROX Performance Coach and holds NASM credentials as both a Certified Personal Trainer and Group Fitness Instructor. A proud mom of three pre/teens and married to her best friend, Trinity holds an arts degree from TCC and has a creative side fueled by a photography passion. Trinity brings heart & hustle to everything she does—especially at CABRA.
