Hints & tips:

  • Avoid moving or swinging your legs.
  • Cross your legs if you have difficulties keeping then steady.
  • The movement should come from contracting the abs, not swaying your body.


  • Strong abs are the foundation of many daily moves such as carrying any object or just raising yourself.
  • A strong core is a requisite for many exercises.
