Split Jacks

Split jacks are a hybrid cardio exercise combining a split-stance jumping jack pattern. You alternate which foot is forward in a small split stance while raising and lowering your arms like a jumping jack. They build coordination, leg endurance, and cardiovascular conditioning with a unique movement pattern.
