About this exercise

A bodyweight core exercise where you sit or recline at a 45-degree angle and alternately drive each knee toward your chest. The angled torso position increases the demand on the abs and obliques compared to an upright seated knee raise.

How to Perform

  • Sit on the edge of a chair or on the floor and lean your torso back to approximately 45 degrees
  • Keep your core engaged and your spine neutral, holding the sides of the chair or placing your hands behind you for support
  • Lift both feet slightly off the floor to find your balance
  • Drive your right knee toward your chest while keeping the left leg extended
  • Lower the right leg back to the starting position as you simultaneously raise the left knee
  • Continue alternating knees in a smooth, controlled rhythm
  • Breathe out as each knee rises and in as it lowers
  • Perform the desired number of reps on each side
