The Spark Lounge is home to the Spark Twins' kids workouts on POWER OF 30. Five follow-along videos for ages 4 to 10 play free here, and new Spark workouts are added here first. It also has the Spark Twins' joke box and two free printables: Spark's Move Sheet and Spark's Snack Guide.

Spark was created by Coach Marla Guloien, a BCRPA-certified trainer in Coquitlam, BC, so kids can move while their grown-ups train with POWER OF 30, her 30-minute online strength program. Sharing with a school or a friend? Send them to powerof30.com/kids.
