About Seated Cross-Body Knee to Elbow

Seated Cross-Body Knee to Elbow brings a lifted knee toward the opposite elbow with a torso turn. It combines alternating leg work and rotation while you remain seated.

What to focus on

Keep the lift small enough to stay steady on the seat.
Return to the center before switching sides.

Make the movement smaller

Lift the knee slightly and use a small turn, leaving space between knee and elbow.

A mistake to watch for

Pulling forcefully with the arms to make contact. Reduce the movement instead of forcing the meeting point.

Practice time and pacing
