Rhea Arvind (B.S., ACE GFI) grew up dancing the Indian Classical dance form, Kathak, and performed her Rangamanch Pravesh in 2019. In 2023, Rhea received her Bachelors of Science (Neuroscience with a Spanish minor) from the University of Arizona. Rhea's neuroscience background allows her to appreciate the often-neglected benefits of exercise: improved mental health and decreased risk for neurodegenerative disease.

Rhea was first introduced to Rayn by her mother, in 2016. She quickly became a dedicated student of Rayn's, building her strength from the inside out. Being Rayn's mentee has profoundly influenced the way Rhea views fitness. Now, instead of using workouts to shrink away, Rhea relies on exercise to help her become her biggest, brightest, and most powerful self. She invites you to join her on that journey.

Rhea is an ACE Certified Group Fitness Instructor (GFI) and loves to lift some heavy weights, dance like crazy, and fight it out at Happy Hour Fitness. The laughter and interpersonal connection that infuse each HHF workout brings Rhea an unadulterated sense of joy and purpose. She hopes to share that same joy with others, supporting them throughout their wellness journey. Rhea strives to foster a warm and safe community where everyone feels loved and accepted. As she always says, "we are all powered by love."
