You will often see a swim bench by the side of a pool.
Swimming coaches use them to help teach technique and as a part of dry land conditioning.
The different strokes can be performed on swim benches, and they are especially useful for butterfly training.
The bench allows coaches to correct flaws, such as dropped elbows and incomplete finishing.
Top swimmers may have their own bench at home so they can train without using a pool.
Benches are not just used by swimmers - athletes from all sports use them to build strength, power, and endurance.
