We get it because we’ve been there.

We know how hard it is to start, when you feel like it may only be a matter of time before you fail again. We know how intimidating it can feel to walk into a gym, especially when you are seriously out of shape and maybe haven’t done anything like this before. But we also know how painful it is to not be able to do the things that you want to do, to feel uncomfortable in your own skin, unhappy with your body, and perhaps facing serious health threats such as diabetes and high blood pressure.

It doesn’t have to be this way.

Discover how Killer Kurves is UNIQUE, and see how it CONTINUES to make a difference for our clients and trainers.

Come As You Are…

…Into our safe, encouraging environment, and experience the support of our close-knit community and the compassion of our trainers who have all lost between 40-160 lbs.

You won’t find judgment here. You will only find others who are on the same journey as you. Everyone in Killer Kurves has a weight loss goal of 40 lbs or more, and even our trainers have been where you are.

You also won’t find shame, crazy-restrictive diets, obsessive calorie counting, “Biggest Loser” style workouts, or anything else like that here. Those things never work long term.

Because we understand the journey that you are on, we designed our program to be different… to help you make changes in your fitness and health that will last, for life.

What’s My Investment?

A high quality personal trainer can set you back $1000-1500 per month.

A nutrition coach can cost you another $400 per month, if you meet weekly.

Want help changing your habits from a health coach? Count on another few hundred per month.

Now, getting your life back and never worrying about your weight again is priceless.

But what if we told you that you can achieve those goals at a fraction of the cost of a personal trainer, nutrition coach, and health coach? And not only would you get coaching in fitness, nutrition, and lifestyle, you would also have the support and accountability of the most welcoming community you could hope to find.

Your investment in Killer Kurves is just $60/week for 12 weeks or $50/week for 24 weeks.

For less than the cost of eating your lunch out each day, you can take control of your life, and get off the diet roller coaster, for good.

Frequently Asked Questions

I am so out of shape, is this for me?

Yes! This program is exactly for you! We understand that many clients coming to Killer Kurves for the first time may not have exercised in a long time. We’ve got you covered. We start slowly at the beginning of the session and progress things as your strength and endurance increases. And we always offer options so that we can continue to challenge you, even if this is your second or third session with us.

Am I required to follow a specific eating plan? What is your approach to nutrition?

In short, no. We provide a meal plan and recipes, but if you have a nutrition strategy that you like and that is working for you, that’s fine. Our goal is to teach you how to put healthy meals together and how to make healthy choices so that you don’t need to follow some sort of plan long term. With regard to our approach to nutrition, we encourage a low-CRAP diet. 😉  We take a very whole-foods based approach to nutrition and will not force you to cut out all of your favorite foods. Rather, we teach you to enjoy things in moderation, to pair foods together in ways that will cut cravings and keep you feeling full, and–most importantly–to discover and address the deeper issues that may be causing emotional eating, stress eating, and other forms of self-sabotage. With regard to supplements, there is no “magic pill” out there, and we won’t try to sell you one.

What do you do in the workouts?

We design fun, efficient workouts that will help you get stronger, feel better, move better, and have more energy. Every workout is different, so you don’t get bored. We focus primarily on whole body strength and resistance training, with some interval style cardio. Everything is low/no impact and we modify/progress things as needed to meet you where you are, in your current strength and fitness level.

How long will I be in the program and what happens when it ends?

Each session lasts for 12 weeks. However, we have many clients who choose to stay on for multiple 12-week sessions. That choice is always yours–we give current clients first dibs on spots in the next session of Killer Kurves.
