Does this sound familiar?

“I was so excited to start. I went to the gym every day, and I was watching every bite I ate. It was great at first, but after a while it was hard to maintain motivation. So I missed a workout, then another… And then I just stopped.”

We hear this kind of thing from new clients all the time.

You’ve tried other programs or routines… made a little progress… lost a few pounds… but then something gets in the way. You get busy at work. You go on vacation. Your family responsibilities make it impossible to stay on track. And sometimes You lose your motivation because the results just don’t come fast enough…

The good news is that we know exactly how to avoid the pitfalls that cause so many people to lose motivation and give up.

It’s a system we’ve developed and refined over the past 3 years, and it’s helped tens of thousands of people just like you finally lose the fat and get fit.
Not only are we going to share our science-based system with you, we’re also going to give you the very best start you could hope for. A start that will set you up for a lifetime of success without relying on willpower.

It's not about what you have to do, it's about who you have to become.

To lose weight, burn fat, and build muscle - you don’t just do something. You must become a new person. The question isn’t so much about what workout to follow or what nutritional plan to subscribe to. It’s about changing your identity so your new behaviors automatically take you there.

Introducing
the 30-Day Built With Science Challenge

Hi! I’m Jeremy Ethier,
founder of Built With Science.

My team and I created the 30-Day Challenge to help you kickstart your journey to better health and fitness.
We’ve designed the challenge to eliminate all of the common reasons people struggle to eat better, lose fat and get fit.
It comes from our proven, evidence-based and wildly successful training programs - programs that have helped over 100,000 people and counting!

The Built With Science system is exactly how it sounds…

Succeed with consistently eating nutritious, filling meals (you won’t be stuck eating bland, steamed kale and chicken breasts day after day)
Succeed with getting to the gym and working out (and enjoying every minute of it!)
Succeed with forming new, healthy habits that will last a lifetime (so you’re not relying on willpower)
Succeed with finally losing fat and gaining muscle - you’ll love how much better your clothes will fit!
And succeed with looking and feeling like a whole new person!

Whether it’s your first time starting a fitness program, or whether you’ve tried before but haven’t found success.

Even if it feels impossible right now. In just 30 days you’ll feel less resistance in your life. And finally become the healthier and fitter version of yourself that you’ve always wanted to be…
A life-changing
30 days
If you’ve always wanted to make a change, but didn’t know where to start. This is the perfect first step for you… and it will set you up for success for a lifetime.
Food
Freedom
Strict meal plans don’t work. That’s why we’ll show you how to eat well, even at social events or at restaurants. And still get the results you want!
Supercharge
your Fitness
It’s not about working harder, it’s about working smarter. We’ll show you the exact exercises you need to do (and how to do them) to get the physique of your dreams.
Support & Encouragement
You’ll get all the tools, support and encouragement you need to make this experience enjoyable, motivating and fun.

This program is perfect for you if:

You don’t know where to start with getting fit, losing fat and finding motivation or discipline
You want to understand why you may have struggled in the past, so it never happens again
You want health and fitness to be a natural and easy part of your life
You want it to be fun (not a chore!)
You want to look and feel better
You’ve tried other programs or fitness regimes but they were difficult to maintain or just didn’t work for you… with us it’s ok if you can’t be 100% consistent

Why are we including all of this at
such a low price? Because I want you to succeed!
I don’t want anything standing in your way to finally get the results you deserve to get.

FAQs

What kind of results can I realistically get in 30 days?

Results will vary from person to person, and depends on your starting fitness level and body weight. But here’s some general guidelines about what you can expect:
An increase in your strength
A noticeable improvement in muscle definition
A reduction of up to 1 inch off your waist size
Lose up to 5 pounds of fat (the heavier you are, the more you're likely to lose)
An increase of 1 to 2 pounds of muscle
A noticeable increase in energy
An improvement in posture
Less bloating
Less achy and stiff, better mobility

Using a food scale sounds like a lot of work. Does your program make eating complicated?

Absolutely not. Our aim is to make eating enjoyable and satisfying. There’s no complicated food prep involved, and you don’t need to use it for every meal. The food scale will actually make eating easier - you won’t be left guessing or wondering if what you’re eating will help you lose fat and get healthy. Everything we show you is backed by science, reliable and safe.

I have a family event that takes place during the challenge. Will I be stuck eating a salad and drinking water while everyone else enjoys their meal and drinks?

We’ve designed this program to work with your life. You can still have a drink and enjoy a meal out. We’ll show you how to make room in your life for these situations, so you never feel restricted or left out

Do I need special equipment?

We’ve designed this program to be as accessible as possible. If you have access to a gym, great, you have more than enough equipment. If you only have access to barbells or dumbbells, we’ll show you how to make that work just as effective. Even if you don’t have access to anything, or struggle from injury limitations holding you back, we’ll provide you with suitable alternatives to make it work!

I’ve never had an exercise routine before. Will this challenge be too advanced for me?

Definitely not. This challenge is great for people who have little to no experience with working out (and even those with more experience). We make things simple and uncomplicated. We’re going to show you everything you need to know to get started, so you never feel overwhelmed.

I’ve tried plenty of programs before. I’ve just never been able to make them last. How will this be different?

This challenge will help you overcome the common obstacles that prevent so many people from sticking with their exercise and nutrition. We help you understand the science behind the exercises and nutrition we recommend. This understanding is part of what will help you make lasting change. It will also teach you a new approach that will accelerate your results and help you keep them for life.

I don't live in the US or Canada, can I still participate?

Yes! The program will be the same no matter where you're located.
