4-Week Nutrition Challenge
4-Week Nutrition Challenge
Build habits that actually last.
September 8 – October 4, 2026
You show up for your workouts. Now let’s make sure your nutrition is supporting all of the hard work you’re putting in.
This isn’t a restrictive diet or a “lose 10 pounds in 30 days” challenge. It’s a four-week coaching experience designed to help you understand your body, your nutrition needs, and how to fuel your workouts and everyday life with confidence.
Whether your goal is to build muscle, lose body fat, improve energy, or simply stop guessing what you should eat, this challenge will give you the foundation to keep making progress long after it ends.
What’s Included:
Online Nutrition Consultation
We’ll discuss your goals, current habits, schedule, training routine, and any nutrition challenges you’re facing.
Personalized Calories & Macros
You’ll receive individualized calorie and macronutrient recommendations based on your goals, activity level, body composition goals, and lifestyle.
Weekly Group Accountability Calls
Join a live Zoom each week where we’ll cover common challenges, answer questions, celebrate wins, and help you stay consistent. An email summary of key points will be sent out to all participants in case you cannot attend live.
Nutrition Education
Over four weeks you’ll learn:
How much you actually need to eat to reach your goals
Protein, carbohydrates, and fats (what they do and why they matter)
How to build balanced meals
How to fuel workouts and recovery
How to navigate weekends, social events, and busy schedules
Strategies for consistency instead of perfection
By the End of Four Weeks You’ll…
Understand your personal calorie and macro needs.
Feel confident building meals without constantly second-guessing yourself.
Develop habits you can actually maintain.
Learn how your nutrition, movement, recovery, and lifestyle work together.
Have a realistic plan to continue making progress on your own.
This challenge is about building knowledge—not relying on another quick fix.

Pilates Strong in 4
September 8 – October 5, 2026
You’ve been showing up to Pilates. You’re getting stronger. But if you’re not seeing the changes you expected, you’re not alone.
The truth is, Pilates is just one piece of the puzzle.
If your nutrition is inconsistent, you’re not eating enough protein, you’re skipping strength training, or you’re barely moving outside of class, your results can stall even when you’re putting in the work.
Pilates Strong in 4 is a four-week coaching experience designed to help you connect all the pieces so your workouts finally work for you.
This isn’t a crash diet, detox, or “shred” challenge.
It’s a sustainable reset that teaches you how to eat, move, and train in a way that supports a stronger, leaner, healthier body.

No matter your fitness level, you’ll leave this challenge with habits you can continue long after the four weeks are over.
