The 75 Project Challenge: How to Transform Your Life with Daily Journaling

The 75 Day Challenge: How to Transform Your Life with Daily Journaling

Introduction

The 75 Day Challenge has taken social media by storm—and for good reason. Whether you're tackling the intense 75 Hard, the balanced 75 Medium, or the gentler 75 Soft, one thing is clear: journaling is the secret weapon that separates those who finish from those who quit.

But here's what most people don't tell you: the challenge isn't just about fitness or discipline. It's about mental transformation. And without the right journaling system, you'll miss the most powerful part of the journey.

In this complete guide, we'll show you exactly how to use journaling to maximise your 75 Day Challenge results, stay accountable, and create lasting change that goes far beyond day 75 (inspired by the challenge, we took a spin creating the project 75 journal).

What Is the Project 75 Challenge?

The Project 75 Challenge comes in three versions, each designed for different lifestyles and goals:

75 Hard Challenge

The original and most intense version created by Andy Frisella. Rules include:

Follow a diet (no cheat meals or alcohol)
Two 45-minute workouts per day (one must be outdoors)
Drink 1 gallon (3.7L) of water daily
Read 10 pages of non-fiction
Take a progress photo daily
Journal daily (often overlooked but crucial)

Best for: High achievers, fitness enthusiasts, those seeking extreme discipline

75 Medium Challenge

A more balanced approach that maintains intensity while being sustainable:

Follow a diet (one cheat meal per week allowed)
One 45-minute workout per day
Drink 3 litres of water daily
Read 10 pages of any book
Journal daily
Practice gratitude

Best for: Busy professionals, parents, those building sustainable habits

75 Soft Challenge

The gentler, wellness-focused version:

Eat well and limit alcohol (one social occasion per week allowed)
One 45-minute workout per day (one rest day per week)
Drink 3 litres of water daily
Read 10 pages of personal development
Journal daily with reflection prompts

Best for: Beginners, those recovering from burnout, wellness-focused individuals

The common thread? All three require daily journaling—and that's not by accident.

Why Journaling Is the Most Important Part of the 75 Day Challenge

Most people focus on the physical aspects—the workouts, the diet, the water intake. But here's the truth: the real transformation happens in your journal.

Here's why journaling is non-negotiable:

1. It Creates Accountability

Writing down your daily progress makes it real. You can't lie to yourself when it's on paper. Miss a workout? You'll have to write it down. Skip your reading? Your journal will show the gap.

The psychology: Studies show that people who write down their goals are 42% more likely to achieve them. Your journal is your daily accountability partner.

2. It Tracks Mental Shifts (Not Just Physical Ones)

The scale might not move for weeks. Your body might look the same. But your journal will show you:

How your mindset is changing
Where you're building discipline
What triggers make you want to quit
How you're overcoming obstacles

These mental wins are what keep you going when motivation fades.

3. It Helps You Process the Hard Days

Day 23? You're exhausted. Day 47? You're questioning everything. Day 68? You're so close but want to give up.

Without journaling, these moments break you. With journaling, you process them, learn from them, and push through.

4. It Turns 75 Days Into Lasting Change

The challenge ends on day 75. But the habits you've built? They continue—if you've been journaling.

Your journal becomes a roadmap of what worked, what didn't, and how to maintain your transformation long after the challenge ends.

How to Journal During the 75 Day Challenge (Step-by-Step)

Step 1: Choose a Challenge-Specific Journal

Here's where most people go wrong: they use a random notebook or a generic journal that doesn't align with the challenge structure.

Why this fails:

No prompts specific to the challenge
No space to track all the daily requirements
No structure to keep you consistent for 75 days

The solution: Use a journal specifically designed for the 75 Day Challenge. Project 75 uses the original creator's ideology, but creates versions of realistic rules, made for a more sustainable focus and long-lasting habits.

Our Recommendations:

For 75 Hard: Project 75 Hard Challenge Journal – Structured daily pages with sections for both workouts, diet tracking, water intake, reading, and reflection prompts. Designed to keep you accountable every single day.

For 75 Medium: Project 75 Medium Challenge Journal – Balanced structure with weekly check-ins, habit trackers, and prompts for sustainable progress. Perfect for busy lifestyles.

For 75 Soft: Project 75 Soft Challenge Journal – Gentle daily prompts focused on wellness, self-compassion, and mindful progress. Includes gratitude sections, realistic rules and emotional check-ins and spaces for leniency cheat meals.

Why these work: They're built around the exact requirements of each challenge, so you never have to guess what to write or track.

Step 2: Journal at the Same Time Every Day

Consistency is everything. Choose when you'll journal:

Morning journaling:

Set intentions for the day
Plan your workouts and meals
Visualize success

Evening journaling:

Reflect on what you accomplished
Process challenges
Celebrate wins (even small ones)

Pro tip: Most successful challengers journal in the evening—it creates closure on the day and reinforces accountability.

Step 3: Use These Daily Prompts

Whether you're using a guided journal or creating your own system, include these sections every day:

Daily Tracker:

✅ Workout 1 completed (time, type, how it felt)
✅ Workout 2 completed (for 75 Hard)
✅ Diet followed (what you ate, how you felt)
✅ Water intake (track throughout the day)
✅ Reading completed (what you read, key takeaway)
✅ Progress photo taken

Reflection Prompts:

What challenged me today, and how did I overcome it?
What am I proud of today?
What did I learn about myself?
What will I do differently tomorrow?

Mental Check-In:

Energy level (1-10)
Motivation level (1-10)
How I'm feeling emotionally
Any cravings or temptations I faced

Gratitude:

3 things I'm grateful for today

Step 4: Track Patterns and Progress

Every 7 days, do a weekly review:

What's getting easier?
What's still challenging?
What patterns do I notice in my energy, mood, or cravings?
What adjustments do I need to make?

This is where the magic happens. You'll start to see:

Which workouts energize you vs. drain you
What foods make you feel best
When you're most likely to struggle
How your mindset is shifting

Step 5: Prepare for the Tough Days

Around days 20-30 and 50-60, most people hit walls. Your journal is your lifeline during these moments. Project 75 drifts away from the all-or-nothing mindset. It regulates intuitive habits & cheat meals, so that every progress instils as a mindset, not a short commitment to fall off again.

When you want to quit, write:

Why did I start this challenge?
What have I already overcome?
How will I feel on day 76 if I quit now vs. if I finish?
What's one small step I can take right now?

Pro tip: Read your past entries. Seeing how far you've come is incredibly motivating.

Common 75 Day Challenge Journaling Mistakes

Mistake #1: Only tracking tasks, not emotions Why it fails: You miss the mental transformation—the whole point of the challenge. Fix: Always include a reflection section, not just checkboxes.

Mistake #2: Skipping days "because nothing happened" Why it fails: Consistency is the lesson. Every day matters. Fix: Even on "boring" days, write something. "Today felt routine, but I showed up" is powerful.

Mistake #3: Being too hard on yourself in your journal Why it fails: Your journal should motivate you, not shame you. Fix: Celebrate effort, not just perfection. "I struggled but didn't quit" is a win.

Mistake #4: Not reviewing your progress Why it fails: You don't see how far you've come, so you lose motivation. Fix: Weekly reviews are non-negotiable. They show you the transformation you can't see in the mirror yet.

What to Do After Day 75

Congratulations—you finished! But here's the real question: now what?

Your journal holds the answer. Review all 75 days and ask:

What habits do I want to keep?
What was too extreme for my lifestyle?
What did I learn about my discipline, resilience, and mental strength?
How can I maintain this transformation?
Should i challenge myself to the next version to unleash your warrior?

The truth: The challenge doesn't end on day 75. It's just the beginning of a new version of you—and your journal is the blueprint for maintaining it.
