How to do it

Straighten your legs and draw one elbow and the opposite knee toward each other as you gently twist, then switch sides.
Focus on slow, controlled movement and feel the core working while keeping your chest lifted.

About Seated Cross Crunch

Seated Cross Crunch begins with the legs extended and the hands near the opposite elbows. Bring one knee inward as the opposite elbow travels toward it through a small turn. Open back out with control before changing sides.

What to focus on

Keep the chest comfortably lifted through the turn.
Return the leg with control before changing sides.

Make the movement smaller

Keep the legs closer to the chair and use a small knee lift with a modest turn.

A mistake to watch for

Pulling the arms down to collapse onto the knee. Shorten the crossing movement.

Practice time and pacing

The app assigns 30 seconds to Seated Cross Crunch. Use that as a time block, with pauses whenever you need them. Move at the demonstration’s controlled pace; the timer is not a repetition target. Watch the full movement once before following along.

Set a firm chair on a nonslip surface and leave room for the arm and leg movements shown. A chair without wheels keeps the setup steady.
