Trini is the highest flyer, the strongest gripper, the most spectacular cartwheeler at her after-school club.

She easily masters any gymnastic move her teachers show her, and always says, "I can do that." But when she tries to construct buildings out of blocks like her friends do, she discovers that some things don't come as easily for her. Through the encouragement of her friends, Trini learns the value of collaboration and trying new things, even when they aren't so easy. An afterword by the founder and CEO of The Little Gym Europe, outlines why it's important to encourage children to try new and difficult things.
