Extension and flexion of one leg in push-up position alternating ► mountain climber

Individual work

Push-up position with your hands supported on a medicine ball (high support, face/look down), alternately bend one leg and lift it slightly off the floor (bring your knees between your arms/to your chest).

Attention:
Keep your upper body as stable as possible (entire body forms a line from the shoulders to the feet), 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; perform the exercise without a medicine ball.

Harden:
Additional weight on the legs.

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

1 medicine ball

2 weight cuffs ► to make the exercise more difficult (additional weight)
