Meet Your Instructor
Hello!
I'm Sydney — I’m a registered dietitian (RD), certified specialist in sports dietetics (CSSD), and a fitness instructor.
I work with individuals doing nutrition and personal training sessions, and with groups giving nutrition lectures and teaching fitness classes.
My aim is to work with you towards any number of health-related goals such as weight loss, sports performance enhancement, muscle gain, improved posture, and improved energy (to name just a few).
I’m here to help you find the balance between committing to a big enough change to stimulate progress but not so extreme that you can’t keep up with it.
Together, we’ll create sustainable and healthy changes.
WE ARE STRONGER WHEN WE WORK TOGETHER

The Complete Bone and Joint Health Plan: Help Prevent and Treat Osteoporosis and Arthritis
— by Jocelyn Wittstein MD & Sydney Nitzkorski MS, RD, CSSD. Countryman Press
A holistic program designed by an orthopedic surgeon and a registered dietitian to help optimize your health at home.
Arthritis and osteoporosis affect mobility, well-being, and longevity, so you can’t leave protecting your joints and bones to chance or to a search algorithm. In tandem with the advice of your own healthcare provider, this easy-to-follow guide offers science-based strategies to start improving your musculoskeletal health today. Learn which nutrients most of us need, which anti-inflammatory ingredients to keep in your kitchen, and which exercises can help improve bone density. The great-tasting recipes provided help fight inflammation and strengthen bones at the same time, with options for omnivores to vegans. The exercises included require minimal equipment, promote balance and strength, and can help decrease the risk of injuries or falls. Specific routines may help even help alleviate pain in problem areas. With clear answers to common questions―including what to ask when you visit your doctor―this book offers the knowledge and confidence to help readers achieve stronger bones, healthier joints, and better mobility for life.
“Sydney Nitzkorski doesn’t just train bodies—she empowers people to move, lift, and live with purpose.”
