Meet Your Trainer, Erin Oprea
Erin Oprea is a former U.S. Marine and one of fitness’s most trusted coaches — having trained everyday women, some of country music’s most recognizable names, and herself for over two decades. She knows firsthand what works at 25, 35, 45, and beyond — and she’s built this challenge around that reality.
The LBC 2.0 is exactly what summer training should look like: quick, minimal equipment, doable anywhere. Not a rep wasted. Proof that you can stay consistent and make real progress even when life is at its busiest.
