Gymco Sports, Grand Rapids

"When we teach—from babyhood—people to move well, they'll enjoy doing it, and they'll continue doing it." Such is the philosophy of Gymco president and co-founder Doreen Bolhuis, which she relayed to the New York Times in a 2010 video report. The importance of starting young kids on the road toward athleticism is something Bolhuis is passionate about, especially as a former elite-level gymnastics coach who's been teaching for more than 35 years. It's a concept she calls "physical literacy," and she's appeared on news outlets such as Today, CNN, and ABC News to discuss how young children's physical training and development is just as important as their mental growth. Along those lines, Bolhuis created the GymTrix line of DVDs to help parents develop babies' fine motor skills and hand-eye coordination.

And Bolhuis's enthusiasm for childhood fitness is apparent at Gymco, where her staff undergoes a four-step technical and philosophical certification protocol on sports development. She has transformed what began in 1980 as a few classes held in a barn behind a local retirement home into a 5-acre, 16,000-square-foot first location and a second, state-of-the-art facility on the north side of town.

When you walk into either site, you'll see kids scaling rock walls, doing back flips, and defying imaginary pirates as they walk the plank-like high beam, improving their physical skills in sports, gymnastics, and cheerleading classes. What aren't as obvious are the internal changes that begin to manifest, from improved self-confidence and perseverance to the gradual building of character. Fulfilling her start-them-early mission, Bolhuis also offers classes designed specifically for preschoolers and kindergartners.
