Individual work

Push-up position (high support, face/look down), alternately bend one leg and lift it slightly off the floor (bring your knees between your arms).

Attention:
Keep your upper body as stable as possible, no hollow back (tense your stomach).

Lighten:
Just hold the basic position (push-up position); barely lift your leg off the floor and/or move it less forwards.

Additional weight on the legs; unstable base (for the arms).

Variant:
Bring your knee diagonally (crosswise) to the opposite arm.
