Screwdriver
At least 15 meters of alternating flutter kicks with straight arms and a minimum of four rotations, with breathing exclusively in the backstroke position. After each rotation, at least six kicks should follow before the next rotation. Each rotation involves a 180-degree turn along the body’s axis. This exercise primarily improves body positioning in the water and shoulder rotation.
Preparatory exercises

Arms too high
The ears should be tucked between the arms; the arms can even extend further back with the head resting on the upper arms. Arms positioned too high are a common mistake: it happens when the child rests their head on their arms in the prone position, then rolls onto the back — the arms end up in front of the face and the face submerges.

Hands down / only turn to the side
In this exercise, the body rotates 90 degrees in both directions, both from the prone and supine position. The hands remain at the sides of the body. In a further step, a complete rotation is performed while maintaining the lateral hand position. This makes it easier to correct the water position on the back and return to the starting position after the 90-degree turn. The change of direction during the body rotation promotes body control in the water.

Flutter kick with board
In this preparatory exercise, the turn is practiced with a swimming board. Alternatively, a pull buoy can also be used. The buoyancy of the swimming board enables the learner to return to a comfortable position in the water without any problems after a turn. The board prevents the face from remaining under water after the turn. However, turning onto the back requires a stronger body rotation to turn the board over. This exercise trains this more intensive rotation.
Common mistakes

Chin and hips down.
The unfamiliar back-floating position often makes children curl up and try to sit upright, or lean back only hesitantly to keep water out of their nose. This makes floating harder. The chin and hips must stay down, so focus on building trust in their own buoyancy through the previous exercises.

Too little kicking
When turning onto the back, the flutter kick must not be neglected. A powerful kick is crucial for resurfacing quickly after the turn and stabilizing the body position. Doing the exercise with minimal kicking would require perfect rotation, body tension, and a stable back position — too challenging at this level, so an energetic flutter kick is highly beneficial.
