Stretch-N-Grow is the world’s largest network of children’s fitness professionals. Stretch-n-Grow was conceived in January of 1992 by Jill and Bob Manly in Galveston, Texas. Their plan was to conduct classes on a local level only. Their home town provided a limited market base of approximately 30 child care facilities. Learn more about their story.
