Marette Boyle, M.ED
The life you want tomorrow is built by the choices you make today.
I've always loved a challenge.
Growing up, that meant horseback riding, soccer, and lacrosse. Today, it looks like CrossFit, wakesurfing on Lake Winnipesaukee, hiking the White Mountains, training for HYROX, and finding every excuse to get outside with my family.
Along the way, I realized something:
Fitness isn't the goal. It's the foundation.
When you train with intention, nourish your body well, and prioritize recovery, you're doing more than improving your health. You're building the strength, confidence, and resilience to embrace life's adventures—whether that's taking on your first HYROX, hiking a mountain, keeping up with your kids, or simply feeling your best every day.
For more than a decade, I've coached thousands of athletes and clients while earning my CrossFit Level 2 Trainer, Precision Nutrition Level 1, and M2 Performance Nutrition certifications. My approach blends evidence-based nutrition with practical, sustainable coaching because I believe your health should enhance your life—not consume it.
Outside of coaching, I also work in wealth management, helping families invest in their futures. While those worlds may seem different, they've reinforced the same lesson: the greatest investments are the ones that compound over time. Your health is no different. Small, intentional choices—made consistently—create extraordinary results.
Whether your goal is improving performance, building muscle, losing body fat, or simply feeling stronger and healthier, my coaching is built around four simple principles:
Train. Nourish. Recover. Live.
Let's build a life worth being strong for.
“Having Marette as a coach with both nutrition and CrossFit has been a huge game changer in my life. I’ve learned how to really love food and balance what I eat with my active lifestyle. Over the past year and a half working with Marette, I’ve notice a lot changes in my life. From my physical appearance, to sleep habits and just feeling great in general has been amazing, Marette has really opened the door for me on what it is to live life and feel great! Thanks, Met!!”
