Stand upright with your feet shoulder-width apart, hold your assault rifle outstretched (at chest height), lift your knees alternately to the height of your navel.

Lighten:
Lift your knees less.

Harden:
Do not put your heels down/stand only on the balls of your feet (additional strain on the calf muscles and more demanding in terms of coordination).

Variant:
Fast exercise execution (knee lift).

1 assault rifle (neutralised)

With your upper body leaning slightly forwards, support yourself against a wall with your hands (arms practically stretched out - facing the wall), rest both straight legs on the balls of your feet with an elasticated band under your feet. Step into the loop of the band with the instep of the foot. From this position, alternately raise one leg (knee at hip height) to further stretch/tension the band and lower it back to the starting position. The respective supporting leg fixes the band to the floor when the training leg is raised. The exercise is similar to running in place, with the knees always raised almost to the navel.

Attention:
The movement takes place exclusively in the hip and knee joint of the training leg.

Lighten:
Choose a rubber band with less resistance.

Harden:
Choose a rubber band with greater resistance.

1 wall
1 mini band

A fixed elasticated band (e.g. on the wall bars, on a post or candelabra) is worn around the hips. Move away from the attachment of the elastic band so that the band is well tensioned. Knee lift (lift your knees alternately with high intensity up to the level of your navel), holding a weight disc overhead with your arms almost outstretched.

Lighten:
Lift your knees less; less weight or no weight at all in the hold-up position.

Harden:
Stronger elastic band; more weight in the hold-up position; additional weights on the legs; knee lift on a soft surface (e.g. small soft mat).
