Raising and lowering as well as rotation of the upper body in supine position (trunk bend) (left) ► cross crunch

Individual work

Lie on your back with your legs bent (feet also bent or flat on the floor), arms bent so that each hand is placed next to the nearest ear. Raise and rotate the upper body to move the elbow (left) crosswise to the knee (right). Lower your upper body and return to the starting position.

Attention:
Do not lower your upper body completely (constant tension), do not pull on your head with your hands (really keep your hand next to your ear).

Lighten:
Lift your upper body less; cross your arms over your chest.

Harden:
Stretch your arms above your head (holding them up) and move your hand (possibly even with additional weight) crosswise to your knee (work without momentum).
