Stacey Graustein

Personal Trainer - Land and Aquatic Instructor

Stacey has a passion for people and for fitness. The phrase that comes to mind when discussing fitness is, “if you don’t move it, you lose it”.

The two largest hurdles to fitness are; first to begin and second to stay with it. Adherence to a fitness plan is one of my main objectives as a personal trainer. Fitness ensures independence which allows one to participate in any activity that is of interest(i.e. golf, pickleball, taking a walk with your dog, hiking, keeping up with your children or grandchildren, running a marathon.) My goal as a personal trainer is to assist the client to find the program they will continue so they will have an enriched life. Exercise is good for your physical well being, your mental health and stress release.

Stacey holds a B.A. degree in business from Southern Methodist University and a B.A. in Elementary Education from Prescott College in addition to several fitness certifications. She is anAFAA certified personal trainer and group exercise instructor. Stacey also holds certifications in Jazzercise, Les Mills Body Pump, and AFAA Mat Core. Her past certification include Spin, Zumba, Turbo Kick and Silver Sneakers. She currently teaches B.O.A.S.T., Beat to Beat, Aqua Stretch and Range of Motion and Drumming classes at Prescott Lakes.

Whether it’s your first time in the weight room or looking for variety in your workout, or  a senior who wants to focus on strength and balance I will dedicate myself to tailor each session to your  specific needs. My 20 plus years in the fitness industry and regular attendance at international fitness workshops qualifies me to help you attain your fitness goals and embrace them for life!

Qi Gong is an Ancient Chinese system of exercise. It can be described as a healing art form that entails breathing exercises integrated with physical  postures, mental relaxation and meditative breathing. Qi Gong has tremendous health benefits, but it is also used for energy cultivation and peace of mind.

Tai Chi began as a martial art form that originated in China, but is today popular worldwide, not so much for combat preparation, but for its health benefits: improved balance and flexibility, muscle strength, and the avoidance of falls. Tai Chi leads to greater vitality and joy!

Both Chinese exercise systems have gained broad popularity, not only for their health benefits, but also for their psychological and spiritual benefits. Millions of people all over the world are now practicing Tai Chi and Qi Gong for recreation, exercise, relaxation, preventive medicine, self healing, and for finding inner peace, balance, and harmony with life.
