Create a Strong Foundation

Whether you have lifted in the past, never picked up a weight in your life or are looking to tweak your current routine I will design a training program unique to your specific goals. All strength programs provide the dual benefit of building muscle and bolstering cardiovascular health. Starting or continuing a strength program is, by far, the most important action you can take toward improving your fitness level!


Increase Strength & Stamina

Group classes are a great way to get in shape in an energizing motivating environment. You will simultaneously lose pounds, increase muscle definition and condition your cardiovascular system. We offer a variety of group classes designed to provide maximum benefit to any fitness level. For more information on which classes would be best suited for you give us a call or check out our class descriptions.


Build Healthy Habits

Healthy nutrition does not come in a "one size fits all" package. Some may need to  address a chronic health conditions, such as diabetes or heart disease, some want to gain muscle while others want to shed excess fat. By using a sustainable habit based approach we address your individual needs and goals by equipping you with a set of tools to achieve and maintain a healthy lifestyle.

Choosing to make the changes to create a healthier more balanced lifestyle takes willingness, sustained effort and community support. Being surrounded by like minded people that believe in you and are working toward similar goals makes the process much more enjoyable and increases your chances of long term success. We'd love to have you join us on your health & fitness journey- call or email to schedule a visit.

InBody BIA testing

How are you tracking your fitness progress? Weight loss can be an important method in trying to live a healthier lifestyle. Most of us use a bathroom scale to track how much weight we're losing. Oftentimes we get stuck on the yo-yo diet rollercoaster where we temporarily find success with a weight loss program only to regain the lost weight..... sometimes even more. We wind up frustrated, confused and wonder what we did wrong. That's because the bathroom scale is misleading.

Ditch the scale.

Your weight is made up of muscle, fat and water. The key to effective weight loss is losing excess body fat, not overall body weight. Weight loss is not the same as fat loss. Instead of tracking how heavy you are, use body composition analysis to track how healthy you really are! Learn how to lose weight smarter, healthier and happier. More importantly learn how to keep it off without falling prey to fad diets or wasting money on useless supplements.

Take control of your health.

The InBody 570 accurately measures your body composition in less than 45 seconds and prints out a results sheet which lists out your body composition components, tracking your progress over time. The device shows key components of your health like:

  • Skeletal Muscle Mass

  • Percent Body Fat

  • Body Fat Mass

  • Basal Metabolic Rate 

  • Visceral Fat Level​

With your initial InBody test & consultation you'll take home a printed body composition analysis, personalized nutrition plan based on the test results, training recommendations and a schedule for retesting.
