Janelle Mistarz

Strength training for all stages of Mamahood.

Janelle knows firsthand how many questions can come with exercising during pregnancy. When she was pregnant with her son, she struggled to find the guidance and support she needed to stay strong and active. She wanted to feel prepared for birth and wondered what her fitness would look like afterward.

That experience shaped her approach to coaching. After her son was born in 2023, Janelle became a ProNatal® Certified Prenatal and Postpartum Exercise Specialist so she could help other women navigate pregnancy, recovery, and motherhood with support and confidence.

With more than 20 years in the fitness industry, Janelle is committed to staying current with research and best practices in women’s health and strength training. A lifelong runner and Boston Marathon qualifier, she brings an understanding of both working toward a goal and adjusting the plan as life changes.

Janelle holds a bachelor’s degree from Iowa State University and a master’s degree in Recreation and Sports Management from the University of Illinois. She is also an ACE Certified Personal Trainer, a National Board Certified Health and Wellness Coach, and an RRCA Running Coach.
