How to get in peak physical shape at any age.
And stay that way.

Don't struggle on your own. Get lasting results you never thought possible with expert nutrition coaching and accountability from Heather Lynn Darby and xlnt Nutrition and Fitness.

To get in shape, you'll need to be consistent. To be consistent, you'll need help.

If you had that, it's very likely you could get where you want to be. Lose the unwanted fat and finally NOT have to stress about slowly adding weight over the years...

What if I could help you design your meals, make sure you were doing the correct types of workouts (no matter where you are) AND help you break the habits that got you in a bit of trouble in the first place?

Lose weight, build strength, and have more energy.

You tell me your goals. I'll help you get there. In under one year, you'll be in better shape than you ever thought possible.

We'll make living healthy a habit.

Most people who try to get in shape overload themselves and burn out quickly. Instead, I'll help you focus on the small practices that lead to big results.

Proven to work, 100,000 times over.

We'll use the Precision Nutrition coaching method, developed by the world's top nutrition researchers and used by champion athletes to achieve lasting change.

I'll help you stay accountable.

I'll provide you with daily support, guidance and accountability, every step of the way, no matter what life throws at you. We're in this together.

Busy? Let me do the thinking for you.

You have enough to worry about already. Leave the nutrition and workout details to me while you breathe easy.

Connected one-on-one coaching.

Develop a close connection with your personal coach, who really knows you. 

It just works better.

"I know what to do... but I have a hard time staying consistent."

When life gets crazy and responsibilities at home and work pile one on top of the other, it's easy to let our health and fitness slip. The years go by and we don't even realize how much our health had declined.

But for most of us, there comes a time when we realize things must change. A time when gaining control over our body takes on new urgency.

For some, it's a scary health diagnosis. For others it's watching a loved one struggle with their own health problems. And for others still, it's when they finally realize they've spent so many years taking care of others, that they neglected to take care of themselves.

When it's time to turn things around and start a new health and fitness program, however, it can be difficult to know what to do next. And staying motivated is hard - especially if you try to do it all on your own.

That's where I come in.

My goal is to help you get in the best shape of your life and stay that way. Starting now.

Transform Your Body Forever

You tell me what you want to do. I'll help you do it. First, I'll learn about your lifestyle, needs, and specific goals. Then, over the course of the program, I'll give you everything you need to look, feel, and perform better than you thought possible.

Proven strategies to help you get (and keep) the body you want

You've probably tried multiple diet and workout programs in the past. And you've concluded that they simply don't work in the long run.

Instead of the all-or-nothing dieting approach, I use a sustainable, practice-based approach to build healthy habits into your life, one day at a time.

The result? You'll lose the weight (and inches) you haven't been able to shed for years. You'll have more energy than ever before. And you'll build physical strength and find new confidence in your body.

Change your nutrition habits forever, and have the results of your hard work really last!

I live and breathe this stuff everyday, and have dedicated my professional life helping people like you become fitter, stronger, and healthier than ever.

Whatever obstacles arise, I'll help you overcome them by modifying your program or offering new solutions. In the end, know that I'm here to support you every step of the way, no matter what life throws at you.

Give me one year. You'll get in the best shape of your life - or your money back.


Stick with me for a full year and follow my recommendations. If you don't get what you're looking for at the end of the year, I'll give you a full refund. You get to decide if the program was worth it. Why do I do this? Because I stand by my work. I know you'll walk out healthier and happier than ever before.
