Personal Coaching with First Principles Health

To see real change, you’ll need to be consistent. To be consistent, you’ll need help.

Transform your body, build strength, or have more energy.

I always start with your needs and goals. Then we’ll work together to develop a plan to help you eat, move, and live better—in a way that works for your body, and your life.

Get the support you need—every step of the way.

I’ll remove all the guesswork and provide the accountability, direction, and support you need to stay consistent, no matter what life throws at you. We’re in this together.

Achieve your goals—even when life gets crazy.

I’ll break your big goals into small daily practices that add up to massive changes. As a result, you’ll progress toward your goals without ever feeling overwhelmed, and build habits that last a lifetime.

Health benefits beyond weight loss.

My science-based coaching method does more than just teach you how to follow a generic plan. In the end, it won’t be just about what you lose, but what you’ll gain: knowledge, control, and the confidence that comes with knowing you’re capable of anything.

No more weird "hacks" or 30-day quick fixes.

You don’t have to go to extremes to get amazing results. I’ll help you achieve your goals without flipping your life upside down.

One-on-one coaching done right.

No cookie-cutter programs here. I will create a personalized plan that’s tailored specifically to your goals, needs, and preferences. Personal coaching is finally affordable. And it just works. Why? Because I am committed to helping you get the results you want.

“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 has 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.

How to take charge of your life — starting today.

Expert deep health coaching and personal accountability from Coach Sebastian Hagemeyer.

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 healthy lifestyle you want

You’ve probably tried multiple programs, detoxes, or restrictive plans 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 have more energy than ever before. You'll be able to trust and take care of your body. And you'll build the skills you need to succeed like you never thought possible!

Stay accountable and consistent with personal help from me

I live and breathe this stuff every day, and have dedicated my professional life to 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.

Build the habits you need to look and feel better for life. (Here’s how it works.)

Easy-to-use online platform

You’ll start by telling me all about yourself, including your goals, health challenges, and daily routine. From there, I’ll customize your entire program and we’ll start the proven coaching process.

Simple practices and daily accountability

Every day, you’ll work on customized lifestyle practice. Each practice will be customized to help you get the results you are looking for.

Small yet powerful practices to improve everyday life

We’ll work together to create and practice healthy habits across every aspect of your life, from sleep and stress-management to movement and mindfulness. These new habits will help you feel more calm, confident, and prepared for each day—no matter what life throws at you.

Personal coaching and detailed progress checking

I’ll check in with you frequently to see how you’re doing and to answer any questions you have. Also, you can message me whenever you need. The program also tracks everything from your measurements to your consistency, so you can see just how much progress you’ve made.

What kind of results do people get?

People who have used this system have been able to achieve results like this.

“I made the commitment to PN to regain my health, happiness, and confidence but most importantly to establish myself as a top priority again. My transformation has been both challenging and exciting, but through PN I have formed and reinforced healthy habits that will support my continued consistency. BOOM!!”

Mia, 37, lost 21 lbs

“I’m a perfect example of someone who knew what to do but wasn’t doing anything about it. I had dramatic changes by simply following the program.”

Bryan, 42, lost 32 lbs

“The three pronged approach of nutrition, exercise and the psychology explorations in self-awareness makes Precision Nutrition Coaching a truly unique program.”

Diana, 67, lost 62 lbs

“At the beginning of the year I dedicated my transformation journey to my Dad who recently passed away. With the support from my PN coach I pushed myself through bad days, and kept smiling on the good days. At the end of it all PN . . . helped me do this for my Dad and to change my ways not in the form of a diet but a life change which I will cherish forever.”

Pedro, 42, lost 34 lbs

“Over the years I've tried countless eating and fitness plans but all of them were either too rigid or too unpleasant to sustain, even for the results they produced. Now . . . I've learned strategies for eating and fitness but also for sleep, self care and connection. I've lost weight but gained so much more joy and peace than I previously thought possible.”

Tracey, 38, lost 20 lbs

“Precision Nutrition has, hands down, been the most important decision that I have made this year. It has tremendously impacted my overall health and wellness, skyrocketed my energy level and even helped me become more adventurous in the kitchen!!! Highly recommend!!!”

Kenneth, 35, lost 21 lbs

“I love that I can wear a two-piece swimsuit. I love eating right and not wanting to kick myself for overeating unhealthy food. I love that I’m buying size 6 instead of 14. And I especially love running into people I haven’t seen in a while and hearing ‘Wow! You look great! And so much younger!‘”

Laurie, 56, lost 51 lbs

“Through PN . . . I got to realize that lasting changes come from deep within; and that self knowledge is essential to acquire a peerless mental status. Once you understand that, you gradually get a trillion dollars mental status and begin to effortlessly flow; that´s when momentum gets you, and you become unstoppable.”

Javier, 42, lost 60 lbs

Is personal coaching right for you?

Personal coaching with Coach Sebastian Hagemeyer is for you if:

You want to get healthier, fitter, and stronger — and stay that way for the rest of your life

This program is for people who want to transform their health, build their lifestyle-related skills, get results that last, and get off the gimmick roller-coaster once and for all. I won’t give you a cookie-cutter program to follow; instead, I’ll help you build habits that will get you results that matter to YOU.

You’re tired of “quick fix” programs and are willing to dedicate time to improve your health - the sustainable way

If you’ve tried something before and “failed” — or just can’t stick with it — know that you’re not alone. And it’s not your fault. After all, self-directed training and nutrition programs fail 98 percent of the time. Not to mention, after all of my time in the Health and Wellness industry, I’ve seen dozens of diet and exercise fads come and go. That’s why I don’t follow fads. Instead, I’ll teach you doable daily actions that are designed to fit into a busy lifestyle. Bottom line: I’ll help you make healthy habits a part of your life, without it taking over.

You want an expert to hold you accountable and keep you consistent through the program

Nothing worth doing can be done alone. That’s why I work closely with my clients to help them live well, no matter what other craziness is going on in their lives. You’re busy and have enough to worry about; let me take care of the fitness and nutrition details so you don’t have to.

Want to get into the best shape of your life? Let me help.

Get the supportive coaching and the accountability you need.

Maybe it’s been a while since you’ve felt the peace of mind that comes with good health, the confidence to do what you truly want, or energy throughout your entire day.

If you’re ready to have the body you deserve and get control of your health and fitness once and for all, I’m ready to help you. No restrictive dieting. No all-or-nothing workouts. Just a science-proven program that fits seamlessly into your lifestyle—and the support you need, every step of the way.

I’ve dedicated my professional life to helping people transform their bodies through nutrition and fitness.

This is your limited opportunity to look, feel, and perform better than you ever thought possible—and build the habits you need to stay that way for life.

I’m ready to help you experience everything a healthy lifestyle has to offer.

But the next step is up to you.
