The cross jump jack is a body-weight plyometric exercise and a cross variant of the classic jumping jack, working the whole body as a conditioning movement. It raises your heart rate while engaging the legs, hips, shoulders, and core through repeated explosive jumps with crossing arm and leg patterns, making it a useful aerobic and warm-up drill.
How to do the Cross Jump Jack
- 1Stand tall with your feet together, arms relaxed at your sides, and your core lightly braced.
- 2Jump up and spread your feet wider than shoulder-width while swinging your arms out and overhead.
- 3Jump again and cross one foot in front of the other while crossing your arms in front of your body or chest.
- 4Jump back out to the wide stance with your arms swinging out to the sides once more.
- 5Jump again and cross the opposite foot in front, alternating which leg and arm lead each time.
- 6Land softly on the balls of your feet with knees slightly bent to absorb the impact.
- 7Keep a steady, rhythmic pace and continue alternating crossings for the full set.
- 8Finish by jumping back to the feet-together starting position and lowering your arms under control.
Form tips
- Stay light on your feet and land softly through the balls of your feet with bent knees to cushion each jump.
- Keep your core braced and chest tall so your torso stays stable while your arms and legs cross.
- Breathe rhythmically and match your arm swings to your foot pattern to keep a smooth, repeatable tempo.
- Start slow to groove the crossing pattern, then build speed once the coordination feels natural.
Common mistakes
- Landing flat-footed or with locked knees, which sends jarring impact through the ankles and knees instead of absorbing it.
- Hunching forward or letting the core go slack, which wastes energy and reduces stability as you cross.
- Rushing the pace before the crossing pattern is learned, which leads to tangled feet and a higher trip risk.
- Always crossing the same leg in front, which builds an uneven rhythm instead of alternating evenly side to side.
Frequently asked questions
What muscles does the cross jump jack work?
As a plyometric body-weight movement, it works the whole body as conditioning — the legs and hips drive each jump while the shoulders and core stay engaged through the crossing arm and foot patterns. It is primarily an aerobic, cardio-focused exercise rather than a muscle-isolating one.
Is the cross jump jack good for beginners?
Yes. It uses only body weight and no equipment. Beginners should start at a slow pace to learn the crossing pattern, land softly, and build speed gradually as their coordination and conditioning improve.
What is the difference between a cross jump jack and a regular jumping jack?
A regular jumping jack alternates between feet together and feet apart. The cross jump jack adds a crossing pattern — you cross one foot in front of the other and cross your arms in front of your body, alternating sides for extra coordination.
How many cross jump jacks should I do?
As an aerobic conditioning drill it works well in timed intervals — try 30 to 45 seconds per set for 3 to 4 rounds, or 20 to 30 reps. Adjust the pace and duration to your fitness level and recovery.
