    Kristine is knowledgeable about a variety of fitness areas and is willing to work around injuries. She is a motivator and has never ending stamina. She is always consistent and is aware of the proper techniques to get the most out of a work out suited to you and to be sure you aren't going to be injured. She puts her clients first and safety first. She is great at pushing you to your limit but knows when your body has had enough! She is a role model to all.

    I worked with Kristine for over a year, first through one-on-one personal training and then as a participant in one of her classes. She was fantastic. Her positive attitude and encouragement helped me achieve many of my fitness goals. I would recommend her to anyone who is interested in pursuing a health and fitness program.

    I had the privilege of taking aerobic classes from Kristine for 3 years. She not only helped our class physically but also emotionally. She stayed current with wellness information and shared ways for us to improve our life. She continually changed our routine which made exercising fun. Her energy was contagious and she pushed us gently to improve each class period. She is an excellent teacher and person who has positively touched my life.

    Our Silver Sneakers Exercise Class was fortunate to have Kristine Aretz as one of our instructors. Her personality and continued encouragement provided the class participants with the motivation to stay focused, improve upon our physical stamina, acquire physical skills to improve our overall health and establish guidelines for future wellness activities. In addition to being a leader for our class she was responsible for periodically reviewing other wellness leaders throughout central Iowa who had similar responsibilities. This experience enabled her to be aware of what other leaders were doing and, thereby, benefiting members of our class. Her constant energy, knowledge of exercise physiology, excellent people skills and encouragement of others have in the past and will in the future benefit the community in which she lives.
