Step by step instructions, muscle activation and variants for the Jumping jack.
Jumping jacks are a full-body exercise that improve cardiovascular fitness, coordination, and endurance. They target multiple muscle groups, including your legs, core, and shoulders, making them an excellent warm-up or standalone cardio workout.
The Jumping jack is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
