How to Do Cross Jack: A Full-Body Cardio Exercise
Introduction
Cross Jack is a dynamic, full-body cardio exercise that boosts heart rate, improves coordination, and burns calories efficiently. This move is similar to traditional jumping jacks but with an added cross-body motion, engaging multiple muscle groups simultaneously. Whether you’re looking to enhance your HIIT routine, warm up before a workout, or simply incorporate more movement into your day, Cross Jack is a fantastic choice.
Muscles Worked
Cross Jack primarily targets:
-
Legs: Engages quadriceps, hamstrings, and calves.
-
Core: Works the abdominal and oblique muscles for stability.
-
Shoulders & Arms: Strengthens the upper body through repeated arm movements.
How to Do Cross Jack (Step-by-Step Guide)
-
Starting Position: Stand tall with your feet together and arms relaxed at your sides.
-
Jump & Cross: Jump while spreading your legs apart and simultaneously crossing your arms in front of your chest.
-
Return & Repeat: Jump again, bringing your feet together and crossing arms in the opposite way.
-
Maintain Rhythm: Continue alternating at a steady pace for 30–60 seconds.
Common Mistakes & How to Fix Them
-
Not fully extending arms → Ensure arms are fully stretched to engage the shoulders.
-
Landing too hard → Keep knees slightly bent to absorb impact and protect joints.
-
Losing coordination → Start slowly and gradually increase speed as you become comfortable with the movement.
