    Erika is a phenomenal trainer and the west coast is so lucky to have her! I truly saw changes during an 8 week session I did with Erika that I had not seen with other workouts. She is hardworking and so knowledgeable and truly cares about the wellness of her clients!

    Erika is a super instructor, trainer and person. She always has a smile on her face, offers lots of encouraging words during those tough workouts and radiates a positive energy. Erika is very attentive in her classes and makes sure that modifications are explained and proper form shown before each exercise. She takes the time to listen to any concerns a client may have about fitness, healthy eating and well being. Erika will be an asset to any fitness center and/or community that she lives in. She practices what she teaches and I am thankful to have had her as an instructor in my fitness journey.

    Erika is AMAZING! I started out taking her spin/ab class and loved the energy she had and it was such a great work out. Then I saw Erika at the Chicago Half marathon last September and she was flying through the race, she's crazy fast!! So 6 months later I decided to do another half but really wanted someone to train me and help me get faster and stronger and most of all get those last 10lbs of baby weight off. Erika's workouts are challenging, I thought for sure during one session that I was having a mild heart attack but she reassured me that is what is called" your max heart rate". By week 3, I was losing weight quickly and toning up. Erika is not one of those trainers that you have a work out then you just see her at the next one. She followed me on my fitness pal and watched my daily food intake and provided me with recipes and food substitutes to help with my sugar cravings. During our run sessions, Erika knew hills were my biggest struggle so she had us run routes that had the biggest hills and every week it got a little easier. So my first race since training with Erika was a 10k. Not only was it the fastest that I had ever ran, I placed 2nd in my division. I was at 8:18 a mile, 6 months prior I was in the 9:00's! So then my half was 2 weeks ago, I knew the course was tough with lots of hills and my goal was to be under 2 hours, I finished at 1:58. Erika will help you reach your goals and make it such a fun, positive experience that you'll want to use her everyday! Thank you for everything, you truly are an amazing trainer that has so much positive energy and just fun to be around!! I wish you all the success in the world, miss you tons!!

    I really enjoyed the 8 week small-group training I had with Erika. She is a very professional, reliable, and dedicated trainer. It is apparent that she truly cares for her clients, as evidenced by the attention she gives to making sure the exercises are performed correctly, her nutritional advice, and motivation both in class and out. Erika saw that the workouts were challenging for each individual, yet attainable and effective. The morning sessions went fast, and I felt energized to start my day.

    Erika is a very knowledgeable instructor! She loves to educate her class during the workouts(ex: what to eat, how to get more out of a work out, what other extra exercises could could be doneoutside of class). She is very energetic and creative when it comes to her class, which makes her workouts tons of fun and leaves you looking forward to her future classes. Erika loves to motivate others to a healthier life style. Good luck to you and your future endeavors! Thank you for all that you have done in this small community! -Marlee Kramer
