Fitness expert Nina Winkler lets you know that the deep postural and supporting muscles need to be activated in order to perform this exercise cleanly. Abdominals and particularly the back reap the benefits, as the center of the body becomes more toned and posture improves along with coordination and balance. The training also includes short stretching elements.

The same lesson applies to this module: precise execution of the moves is more important than speed. Take your time and pay close attention to instructions from Nina and co-leader Marlies.
