What does glide mean in swimming?

Definition of Glide in Swimming

Swimming Glide is a smooth movement throughout water without using arms or legs for propulsion.

In most cases, gliding happens after underwater turn completion (the flip or open turn).

Professional swimmers usually keep their body streamlined, while their legs should be straight back while arms should be pointing forward in front of the head while gliding after turn.

Glide is simply a "pause" while diving. Some trainers suggest gliding exercises to improve after turn dive balance and length.
