Starting Position

The head, back and buttocks are placed on the bottom. The knee joints are stretched. The feet and knees are in direct contact. The upper legs are kept 5-10cm over the bottom. The shoulders are detached from the bottom. The arms are stretched, the palms point down forward. The VarioSling is tensed.

Final Position

The buttocks are placed in the air and the legs are vertically stretched upwards. Back and head are on the bottom. The hands are located under the knees and besides of the upper leg. The arms are stretched and tensed.

Movement 1

The stretched arms are brought into a vertical position while the hip or buttocks are lifted as well. The stretched arms get pushed against the resistance of the VarioSling to create back-pressure. Thereby the balance is secured.

Movement 2

The stretched legs get slowly and controlled back into starting position.


Try to lift your buttocks or hip very clearly, to stress the deep abdominal muscles in an optimal way. You can lift your upper body, to create a higher tension in the abdominals.
