Step by step instructions, muscle activation and variants for the Stepping Jack.
The step jack is a low-impact alternative to the jumping jack that replaces the bilateral jump with a controlled lateral step, making it suitable for warm-ups, active recovery, or beginners who need to reduce joint impact while still elevating the heart rate.
The Stepping 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.
