Hey there! My name is Marissa Rivera-Davis (she/her). I'm a PN-certified nutrition coach, GGS-certified women's coaching specialist, licensed Zumba® Fitness and Circl mobility instructor, and the founder of Her365 Fitness, a studio/gym and wellness community for womxn.

Founded in 2018, our mission at Her365 Fitness is to provide comfortable, affordable, and supportive fitness options for womxn who want to prioritize their self-care in an environment where they feel welcome and can be their authentic selves without the fear or intimidation that can be felt in standard fitness spaces.

I am passionate about helping womxn tap into their authentic selves so they can activate and reinforce their self-confidence and inner strength and develop self-care practices that feel good, that they enjoy, and that they can finally stick to.

Drawing from my lived experience and ever-deepening relationship with my heart & my body, I also offer workshops for womxn and teen girls that invite them to explore developing intuitive, values-based self-care practices that they can adapt throughout their lives. My workshops are interactive and feature activities that support confidence building, foster self-sufficiency, encourage sisterhood, and present skill-building opportunities for womxn around advocating for themselves in their daily lives.

In my THRIVE365 and StrongHer Beginnings nutrition, movement, & lifestyle coaching programs, I work with womxn 30+ who are devoted caretakers of others and who need help prioritizing and sustaining their health, fitness & wellness self-care practices. My approach with each womxn is holistic -- everything affects everything -- with a particular focus on exploring their mindset and beliefs around their body, how they choose to eat, move, manage stress, and rest so they can finally break free from the harmful cycles of dieting and the pursuit of body-image "ideals."

I advocate for and support womxn in practicing self-compassion, self-exploration, and self-trust so they feel empowered to live authentically and more joyfully in the body they have right now.

I am a 40+ cisgender womxn, and I identify as Queer and Black/Afro-Latina/Boricua. I’m the mother of 3 grown-ish humans and several furry, shelled, and finned animals. I have been married for 20+ years (8 of the early years I was a military wife during OEF/OIF). I am living with and managing uterine fibroids and how they affect my energy, body composition, and quality of life.

As of Sept. 2023, I am recovering from surgery that repaired a torn ligament in my knee. My body has changed a lot during this process and I am navigating all that comes along with the changes. As my body heals, my self-care plan keeps me focused on my nutrition along with physical activity within my ability to support body recomposition (fat loss & muscle building) and my mental health.

I live life guided by my intuition and an innate love of spreading joy through movement and dance. 🖤
