The assisted Crunch belongs to the standard exercises of the abdominal training. The straight abdominal muscles get stressed in an optimal way. This version is very intensive for the abdominal musculature due to the permanent tension. The straps of the VarioSling have an angle of 60-45 degree and point towards the legs. The suspension point is placed behind the head.
