When standing upright, hold an object (e.g. helmet or rucksack) at chest height with arms almost outstretched, lunge forwards, bend the front (and back) leg to a right angle (back knee briefly touches the floor), rotate the upper body/object to the side of the front leg and back in the lunge position (gaze accompanies the movement), push off the front leg to return to the standing position in the starting position. Switch sides for the next exercise.
Attention:
Always keep the front knee behind the tip of the foot and centred over the foot. Distribute your weight over the entire front foot. Keep an upright posture (tense torso), push the front knee outwards (do not tilt inwards).
Lighten:
Less weight/load; lower the upper body less (greater angle in the knees).
Harden:
More weight/increased load.
Variant I:
Push off the back leg to return to the standing position. The lunge creates locomotion.
Variant II:
Instead of bringing the front leg to the standing position, the back leg is brought directly forwards and the knee is bent (new lunge), creating continuous locomotion.
