Oblique Jumping Jacks


  • Great variation to the traditional Jumping Jacks.
  • Strengthens and tones the oblique muscles.
  • Increases heart rate to improve cardiovascular response.

How to do Wacky Jacks:

Starting Position: Stand with your feet slightly wider than hip-width apart. Position hands at goal posts with a 90 degree bend at the elbow, palms facing forward.

Movement: Drive one knee up and out to your same side elbow, bringing your hip past 90 degrees and bending at your sides. 

Return: Return your foot to the ground and repeat with your other knee to the other side. 

Modification and Progression:

  • To simplify Wacky Jacks, slow down the tempo by marching the knee out instead of jumping. 
  • To advance Wacky Jacks, increase the tempo and/or raise the arms overhead, biceps near the ear. 

Movement Tips:

  • Engage your core by tucking your tailbone in and drawing the navel to the spine.
  • Driving the knees and hips up and open requires hip flexibility – to increase this, spend time in the Frog Stretch.
  • Create as much space between your ears and shoulders by extending the crown of the head tall and pressing wings of your back down.
