We perform the exercise with the face underwater and holding breath because of the better body position. When we feel the need to inhale, we rise the head, inhale and immerse the face underwater. During the performance we focus on:

• feet we need to extend and turn inwards,
• leg extension in knees when finishing the kick,
• appropriate amplitude and frequency of the kicks,
• appropriate depth of the kicks, so we make bubbles with feet

                                           and

• arms and body extension,
• fixed head position on the surface in the body extension.
