As fitness professionals, our personal trainers help clients by motivating them to make exercise a fun part of their lives. Whether it's improving your overall health and wellness, or seeking fitness through strength training, helping you get out of bed without pain, running faster, jumping higher, or learning about your weight management options to reach your fitness goals, we're eager to help start you on a journey that could change your life forever.

Here are the areas of fitness we specialize in:

Baby Boomer/Older-Adult Training, High-Intensity Interval and Tabata Training, Small Group or Partner Training, Mixed Martial Arts Inspired Workouts, Boot Camps, Training for Women, Youth Fitness, Strength Training or Body Weight Training - we're ready to guide you in achieving your fitness and health goals.

Our nutrition program, Nutrition Together*, isn't about dieting. It's about giving you the knowledge to change how you eat. Nutrition counseling sessions will cover topics ranging from how to eat light (and enjoy it) to grocery shopping, dining out and changing unhealthy eating behaviors.
