"Baby Boot Camp is an innovative stroller fitness program that helps moms regain or enhance pre-pregnancy fitness levels and meet the physical challenges of parenting by emphasizing strength training in a supportive environment.
Born out of necessity, Baby Boot Camp arrived shortly after Kristen Horler's first child in August 2001.
After extensive research, she was unable to find a challenging workout that didn't require hiring a personal trainer and a babysitter or purchasing a gym membership.
Drawing from her experience as a group fitness instructor, personal trainer, triathlete and mother, she developed Baby Boot Camp to balance the fitness needs of new moms with their desire to spend time with their baby." Source: About Baby Boot Camp
