Why try a fitness boot camp?

Accountability to yourself and the instructor

Unlike a traditional gym membership or self guided exercise program, boot camps are designed to motivate you to succeed. When you workout on your own, chances are slim that you will push yourself that extra mile, (or that extra rep). Not so with our programs! Your local, Dulles/Sterling/Leesburg, Virginia boot camp instructor is an experienced personal trainer who knows how to motivate and encourage you to go above and beyond what you think you can do.

Mix It Up

Variety is the spice of life and one of the reasons fitness boot camps are so successful. Your SFC boot camp instructor will implement a wide range of exercises – including cardio and strength training – to keep your workouts fresh and challenging.
Variety also adds another important component to your workouts. Doing the same workout, day after day, allows your body to reach a plateau. When you mix it up each session you can count on body weight exercises, quick bursts of cardiovascular workouts, and strengthening exercises.

Professional Trainers – The Pros Know

Nothing can take the place of professional knowledge. For the same reason you go to a doctor, you should seek the advice of an expert when it comes to fitness and weight loss. The professional trainers at Sergeant’s Fitness Concepts will observe your current level of performance and help you reach your goals. He or she will keep you from doing too much too fast, and keep you from sitting on the sidelines while others pass you by.

Most importantly – improved results

SFC boot camp instructors know how the human works and will help you burn the fat without the need for diet pills and extreme dieting. Boot camp workouts boost your metabolism and enhance your body’s ability to burn fat – your instructor will work to help you burn the maximum number of calories every time you meet.

So don’t wait, get started today and try a free week at a fitness boot camp location in the Dulles/Sterling/Leesburg, VA  area with Sergeant’s Fitness Concepts.
