Addy Fahrenkrug En Fuego Fitness

Addy Fahrenkrug

I am co-owner at En Fuego Fitness and teach Zumba, BodyPump™, BodyCombat™, and CXWorx™.  I was not always a fit and healthy individual.  I struggled with my weight throughout college and through 2 of my pregnancies, I had very little will power in the way of food and very little motivation to workout.  I fell in love with fitness when I became addicted to Zumba Fitness classes in 2007, which helped me to lose 60 pounds!  Since then it has become my passion to help others find their way to a healthier lifestyle through FUN exercise.  Besides holding my Zumba Fitness License, I hold certifications in Les Mills BodyCombat™, BodyPump™,  CXWorx™, an AFAA Certification in Group Fitness and my ACE Certification in Personal Training. I am married to Chad and we have four wonderful children, we reside in West Bend.

I am co-owner at En Fuego Fitness.  I am certified to teach Les Mills BodyPump™, BodyFlow™, BodyCombat™, CXWORX™, and licensed to teach Zumba. I am also a BeachBody coach and Herbalife distributor. I have a bachelor's degree in Physical Education, as well as minors in Health and Coaching. My favorite part of owning En Fuego Fitness is getting to know the people who come to the studio, and helping them achieve their goals. I love to have lots of fun in class! Outside of the studio, I live in Jackson with my husband Luke, and our three girls.

I have been a Certified Les Mills Group Fitness Instructor since 2004.  The Les Mills classes have allowed me to inspire others through the pre-choreographed workouts.  The biggest reward for me  has been to see the results individuals receive through these programs.  I am also a Les Mills U.S. Trainer for BODYPUMP®, BODYFLOW® and CXWORX®, and I have successfully obtained Group Fitness certifications from ACE and AFAA.

I have three daughters, and reside in Jackson with my husband Mike.  My full time job is an Account Executive working for HumanaVitality, a wellness incentive based program.  I travel to large employers across the country to educate them on wellness programs.

I love zumba and I have been certified instructor for 2 years.  I love the energy in every class and the days I teach are my favorite days of the week.  Over the last two years zumba has helped me loose 40 pounds and it was so much fun doing it!  I am easy to follow and I make every class a fun sweaty good time so come check it out!   When I am not teaching Zumba I love taking the Body Pump classed at En Fuego.  The instructors got me hooked immediately.  I reside it West Bend.
