Personal Coaching with LifeChange Fitness

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

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.

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.

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.

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.

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. More on the evidence below.

Affordable one-on-one coaching.

At $99/month, personal coaching is finally affordable. And it just works. Why? Because I am committed to helping you get into the shape 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 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.

Stay accountable and consistent with personal help from me

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.

Here’s an inside look at how
the personal coaching program 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 12-month coaching process.

Simple nutrition habits and daily check-ins

Every day, you’ll get a lesson and a nutrition or lifestyle habit to practice. You can either read the daily lesson or listen to it like a podcast. We’ll practice a new nutrition habit every two weeks, with every lesson designed to help you get results.

Small yet powerful habits to improve everyday life

Along with your nutrition habits, 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 habits throughout the year, 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 was a chronic yo-yo dieter always looking for an answer. Precision Nutrition is the first and only plan to ever help me in 40 years of dieting life. I am off all medicine and no longer have to use my CPAP machine. Precision Nutrition helped me win back my health.

Cindy, 50, lost 70 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

I used to be an emotional eater. I never expected to become a person who could release my stress through exercise. I don’t regret one day of this last year. It was exactly what I needed to get myself back on my feet and feel fulfilled again. Not just because I lost weight. But because I now have the confidence to feel like I’m worth it.

Jill, 25, lost 55 lbs

Precision Nutrition Coaching has been an investment in myself on a long-term, consistent basis. That was a huge change from what I used to do — trying to get into shape on a short-term basis where I would just get burned out and go back to my old habits. And coaching really gave me a person who was looking out for me and helped me stay consistent.

Tim, 36, lost 100 lbs

I didn’t use to take time to appreciate my body, and the last 15 years my weight has been up and down. I knew when I started Precision Nutrition that it would be the last thing I tried. I feel like I’m at my best right now—it was a year of fun, excitement, change, and triumph.

Jodi, 34, lost 51 lbs

I can’t thank you enough for all that you’ve done for me. Between buying and renovating a home, growing my family from one child to two, and continuing to watch my business grow, PN has given me the confidence and strength to keep going.

Adam, 28, lost 40 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

I love the fact that I could tap into the shared knowledge of thousands of people who had done this before. I look at myself and compare what I accomplished in one year to 16 years of doing it on my own.

Andrew, 43, lost 51 lbs

Is personal coaching right for you?

Personal coaching with Coach Karen and Precision Nutrition 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 lose weight and body fat, build physical strength and confidence, get results that last, and get off the diet roller-coaster once and for all. I won’t give you a crazy diet or exercise program to follow; instead, I’ll help you build habits that will get you results that last forever.

You’re tired of “quick fix” programs and are willing to dedicate 12 months to getting in shape 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 many years in the fitness 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 fitness and nutrition 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 eat well and exercise, 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.

Pricing

Hiring a personal trainer can easily cost as much as $500 per month. And that’s often just for the exercise program!

But if you join me right now, you’ll have the opportunity to pay only $99 per month for 12 months.

This includes:

  • Personal nutrition, movement, and lifestyle coaching with me for a full year.
  • Delivered on a premium, easy-to-use platform you can take with you anywhere.

I only take a small number of new clients every year, and spots are first-come, first-served.

Program starts April 15!
