Interested in working with the Best Personal Trainers in McHenry County and in Lake in the Hills?

Upon entering the local gym, many of us feel overwhelmed. We had our one hour orientation but still find ourselves asking; "What do I do now?", "How do I work this equipment?", "What type of activity will make me lose weight, make me stronger, or change the shape of my body?", "Should I be doing cardio all of the time and if I should, how long should I do it?", "What is this "fat burning" thing all about?", "Will weight training make me bulky?" We here at K-Star Fitness can identify with your frustrations. We personally have "been there, and done that". Let's get rid of what doesn't work and replace it with what DOES work utilizing our vast experience through practical education and knowledge. Let us help you get in the "Best shape of your life" through exercise and nutrition.
