About FIT By GP

Welcome to FIT By GP — where fitness is about feeling strong, confident, and limitless, not chasing perfection. I’m Gwen Perez, a certified personal trainer and wellness coach, and I created this space to help women in their 40s and beyond build strength, improve energy, and move with freedom.

My approach combines muscle-building, proper protein intake, mobility work, and realistic nutrition habits to support hormone balance, reduce pain, and boost confidence. Living with Hashimoto’s taught me the power of compassion and consistency, and I bring that same mindset to every client.

Here, we focus on meeting you where you are, creating programs that feel doable and sustainable so you can thrive at home, in the gym, and in life. If you’re ready to redefine what strong feels like, let’s take the next step together.

Personal Trainer

Hi! I’m Gwen Perez, the heart behind FIT By GP. As a certified personal trainer and nutrition coach, I bring over a decade of experience and a deeply personal understanding of what it means to build true strength. Living with Hashimoto’s has taught me the importance of compassion, flexibility, and meeting each person exactly where they are. I specialize in helping women in their 40s and beyond feel strong, confident, and empowered through strength training, protein-focused nutrition, mobility work, and mindset coaching. My approach is all about creating realistic, sustainable habits so you can move freely, feel energized, and live life without limits.
