Their lean muscle mass and limited upper-body flexibility gives them very sinky legs when swimming. This means that one of their primary areas of focus needs to be improving their body position.

build with limited swimming experience. Co-ordination in the water is a key concern and learning to improve their rhythm, timing and catch will really aid this.
In terms of limited experience,

Their stroke is characterised by a very dominant and propulsive leg kick but lacks catch and feel for the water with their arm stroke. As kicking is a relatively inefficient method of propulsion, and uses very large muscle groups, this swimmer is often short of breath.

Common trait - a very conscientious approach towards developing their swimming technique! Their stroke is typically long but contains too much glide and has a distinct dead-spot within its timing.

The Swinger nearly always has good swimming experience and feels confident in the water. The key characteristic of the swinger compared to the Smooth type is that they have less body roll, meaning their arms tend to swing round the side of the body rather than travel over the top.

The Smooth can  has an excellent swimming background. They appear to be perfect in the water and to exert very little effort whilst cruising past their opponents. Their stroke may require some adaptations to perform at their potential in open water.
