Modified crawl is a swimming technique that is also known as sidestroke. While it is a popular and widely-used swimming technique, there are also other synonymous ways to swim. One of the most common synonyms of the modified crawl is the breaststroke. This swimming style involves the swimmer's body being submerged in water while the arms and legs move in a coordinated manner. Another equivalent swimming technique is the freestyle, also known as the front crawl. This technique focuses on alternating arm and leg movements and offers more speed and agility. Additionally, swimmers can perform the backstroke, which involves swimming on the back, with face up and arms and legs moving together in a coordinated manner.
