​ Marco Bonfiglio, Trainer

Meet Marco Bonfiglio our new trainer.  Marco has education and also a lot of experience. Marco attended Bluefield College in VA as a student athlete and graduated with his Bachelor of Science in Exercise and Sports Science.  Marco is bringing great knowledge of heavy weight training to the gym to provide guidance to our clients who want to gain strength with heavy weight training.  As a former college athlete, athletics and fitness were a huge part Marco's life. Getting into weight training was the best decision he ever made. After high school it was apparent that exercise science was the best path he could choose. The studying he did in undergrad helps hem everyday in his profession. The concepts learned in the degree transfer over to the real certifications in the fitness industry. As a Bachelor of Exercise Science the next certification Marco plans to go after is the NSCA certified strength and conditioning specialist. Down the road still planning to go on to Master's program or possibly a doctorate in the medical fitness fields. The best part of this field is being able to learn everyday but also to teach everyday. Marco is very knowledgeable in biomechanics, exercise physiology, testing and prescription, and metabolic training.
