Coaching designed for the body you're in now.
You are not a template — and your coaching shouldn’t be either. I work with women whose bodies have changed and need a smarter, more responsive approach to training and nutrition. This isn’t about doing more. It’s about doing what actually works — based on how you eat, move, sleep, recover, and respond. Every plan is built intentionally, adjusted thoughtfully, and designed to support long-term results, not short-term burnout.

The Metabolic Truce™ Protocol is a structured 8-week system that integrates nutrition, resistance training, and strategic cardio into a clear, repeatable framework. Each week builds on the previous one, allowing you to apply what you learn in real time rather than constantly starting over. The focus is not on doing more, but on doing what works, consistently.

CRUSH !T Coaching: The Metabolic Truce™ Strength Training Protocol
The Metabolic Truce™ Strength Protocol is an 8-week strategic strength training plan designed for women who are tired of piecing workouts together from random reels, hopping from program to program, and wondering why their body composition is not changing despite “working out.” This is not bootcamp chaos, influencer fluff, or a sweat-until-you-collapse approach to fitness. This is structured, progressive resistance training designed to help you build muscle, improve body composition, increase strength, and train with purpose instead of randomness. Whether your goal is to improve muscle tone, build strength, increase confidence in the gym, or create a more intentional training structure in midlife, this program removes the guesswork and gives your body a repeatable signal it can adapt to. This program focuses specifically on strength training progression and execution and does not include individualized nutrition coaching, macro coaching, or meal planning.

Metabolic Nutrition & Fitness Coach
When it comes to health and fitness, I lead by example and believe sustainability matters more than intensity. After years of coaching women through changing bodies and busy lives, I’ve learned this: there will always be another 12-week program, another 30-day challenge, another so-called “transformation.” But what happens when those things end? Building a healthy relationship with food and fitness is a lifestyle choice — not a one-night stand. When I work with clients, we build from the ground up, focusing on nutrition, strength, and habits that support long-term metabolic health instead of quick fixes. This is coaching for women who want to feel capable, strong, and confident in their bodies — not constantly starting over.
What working together actually looks like...

Progress & Pattern Tracking
We track what actually matters—training consistency, recovery, nutrition habits, and trends over time. This helps us spot patterns, make smart adjustments, and keep progress moving without burnout.
Activity & Recovery Insights
If you use a wearable, we can integrate activity data to better understand. movement, recovery, and overall workload—supporting smarter training decisions without obsessing over numbers.
Weekly Feedback & Adjustments

Nutrition-Forward Guidance

Strength-Focused Training Plans
Your workouts are built around intelligent strength training, strategic cardio conditioning, and sustainability—designed to support muscle, metabolism, and long-term results.
Frequently Asked Questions
Who is this coaching best suited for?
This coaching is best suited for women who feel like they’ve been doing “all the right things” but aren’t seeing the results they expect. Many of my clients are already exercising regularly and eating relatively well, yet still struggle with stubborn fat loss, plateaus, or a body that no longer responds the way it used to. If you’re looking for a more strategic, personalized approach that works with your physiology instead of against it, you’re in the right place.
Who is this program NOT for?
This program may not be right for you if you're looking for: — Quick fixes, extreme dieting, or a one-size-fits-all approach. — If you’re not open to structure, consistency, and making thoughtful adjustments over time, this likely won’t be the right fit. — The work we do here is intentional, data-driven, and designed for long-term results—not shortcuts.
Is this program right for me if I'm already active?
Yes—and in many cases, those are the clients who benefit the most. If you’re already working out consistently but not seeing changes in body composition, it’s often a sign that your nutrition, recovery, or overall strategy needs refinement. This is where a more precise, individualized approach makes all the difference.
What are the different ways to work with you?
All programs are offered under the CRUSH !T Coaching framework—a structured, physiology-based approach to training and nutrition—with current offerings designed to meet you at different levels of support: — The Metabolic Truce™ Intensive (Primary Offering): A fully personalized high-touch coaching experience with ongoing adjustments, weekly check-ins, and direct support. — The Metabolic Truce™ Meal Planning: A structured nutrition plan designed for those who want guidance without full coaching. — The Metabolic Truce™ Subscription (Post-Program): Ongoing support available after completing initial programming, for continued structure and accountability. Most clients begin with the Intensive for the most comprehensive and effective results.
Do I start with the Intensive or Meal Planning?
If your goal is meaningful change in body composition, breaking through plateaus, or fully understanding how your body responds, the Intensive is the best place to start. Meal Planning is a great option for those who want structure and direction but are not ready for a fully coached experience. If you’re unsure, the initial assessment will help determine the most appropriate starting point.
