This Fit Challenge Includes Everything You Need To Gain Strategic Muscle While Leaning Down.

Take the guesswork out of planning workouts and make meal planning easier with meal quides tailored towards specific needs and your lifestyle. No more Googling exercises, either - each workout has video exercise demonstrations.

The FitU Challenge and training will help you overcome your biggest obstacles so you can finally have the physique you've always wanted:

★ Week 1: Foundation

The first two weeks are intro weeks, but they’re much more challenging than they look on paper! 2 lower body days, 2 upper body days, and one HIIT/metabolic day for a week that’s focused on sculpting beautiful shoulders and glutes. Supersets up the intensity, while saving you time in the gym.

★ Week 2: Foundation +

You’ll be introduced to finishers, your new fat-burning friend. The overall structure this week builds upon week one, but you’ll see an increase in volume this week. Workouts will still be challenging and continue to take 45 min – 1 hour. You'll start to get excited about the progress you're making!

★ Week 3: Specialization

You’ll start focusing on sculpting that X-frame (broad shoulders, small waist, shapely legs), as the days become more specialized. We’ll start applying new techniques for gaining strength and gaining strategic muscle. HIIT and Supersets will help you get lean.

★ Week 4: Momentum

You'll continue to focus on building and chiseling your X-frame Masterpiece. Big compound movements, along with giant sets, finishers, HIIT, and decreased recovery between sets all contribute to a lean, athletic frame with strong curves. Gaining momentum!

Your Challenge Enrollment includes:

✔ Instant Access to The 4-Week FitU Challenge
Workouts, Meal Guides, and Other Resources
✔ Fit University Support Group (30 Day Access)
An Experience That Can Change Your Life

Can I do this program if I work out at home?

This program is best done at a gym with basic equipment like free weights, cables, and
basic machines. If you have a well-stocked home gym, I can help with exercise substitutions.

I need to lose weight, is this program for me?

Yes! We’ll focus on inches lost, rather than weight lost. This program can help you gain muscle while losing body fat.

Do I follow the meal guide exactly?

The meal guide is meant to be tweaked according to your height, weight, age, and BMR.
There are calculators and detailed docs that walk you through exactly how to do it!

Do you have meal guides for vegetarians?

Meal guide types include vegetarian, vegan, keto, calorie cycling, gaining muscle, and more meal guides come out each month inside The Fit University Membership!

Do I have to pay for any future updates to The FitU 4-Week Challenge?

There is an optional upgrade after the 4-Weeks so you can continue gaining momentum, get the next phase of workouts, meal guides each month, and access to Erin's Members-Only Support Group - The Fit University monthly membership.

I just joined. I'm Excited! Where do I start?

Week 1 workouts are a great place to start. Be sure to look over all of the meal guides,
as you may find one in later months that suits your needs better. Also, be sure to request to join the Members-Only Facebook group. Introduce yourself and your goals or just soak it up and enjoy your 30-Day access.

"Erin is amazing. She has Given me the tools I need to change my body. This is not some quick fix method to drop weight fast. Nope this is giving you the tools for different lifestyle that you can maintain and that you understand. I've never had that before with any other Program. I couldn't believe the transformation and my body and the 5 week program and I'm learning even more and this monthly program. Sometimes I can't even believe how much you get for so little! I've been spending less time at the gym thanks to Erin teaching us how to work more effectively. If you're even thinking about doing this stop thinking just do it. If you walk away with even one new habit it's priceless."

"Erin's online fitness challenges are just the ticket regardless of where you are in your fitness journey!"

"Erin's online fitness challenges are just the ticket regardless of where you are in your fitness journey. You get a detailed meal guide with clear education on WHAT to eat, WHEN to eat it and WHY - she's extremely knowledgeable about nutrition, supplementation and how our bodies work. She also goes out of her way to create appropriate plans for folks that practice a particular lifestyle, like Keto or vegan.  She doesn't just tell us WHAT to do, she explains the WHY - so that you're not just robotically following a set of exercises, but rather get to know your body and apply what you learn going forward. She's generous to a fault with her time and her knowledge. And she sets an example by working hard herself. It's a pleasure to watch her - and very much keeps me accountable. We should all be so lucky to have a coach like her. I know I am..."

"Erin Stern is a consummate professional. I have the privilege of working with her within the challenges she offers. She is just as kind as she is knowledgeable. From my work with her, I have decreased body fat, increased muscle, strength, and gained so much inspiration and knowledge.

She created an environment of supportive women, through her challenges that root you on no matter your level of fitness, from the beginner to the competitor.

Her plans are effective and efficient. No spending 2 hours in the gym.

She is the real deal. I am happy investing in myself with her assistance."

"I started with Erin, over 8 weeks ago. I have never enjoyed other workouts programs as much as hers! In recent years I have tried others and never gained the satisfaction and enjoyment as Erin's! Her workout plans are attainable all while adjusting weights to suit Me! She has given very clear and precise instructions with videos of each exercise. The workouts are structured to achieve your goal! I think seriously...she is the BEST COACH EVER! Erin is quick to reply to your concerns Questions and Answers to continue moving forward, she is enthusiastic very supporting with a POSITIVE ATTITUDE all while she herself is just down to the earth a super nice person! Huge thank you Erin Stern”. Just Luv ya, the whole entire perfect package to achieve my goals and be ME! The BEST TRAINER EVER!"

What a few more are saying...

"I actually work in customer service for another high-end members-only fitness website where I get all my content for FREE (members pay between $57-$199.00 a month to belong). I thought I would try out an Erin Stern challenge just for something different and expected to cancel after the month was up. I was pleasantly surprised by the quality of the workouts, and more important, the amount of personal interaction Erin provides to the group members! Definitely worth the money plus some!!!"
