Swimmers that are at least 18 years old with little or no previous swimming experience can join an Adult Beginner class. During lessons swimmers will use the aids provided to build confidence in the water and to develop basic techniques for front crawl, back crawl, and breaststroke. Once swimmers are ready, they will also have the opportunity to practice swimming short distances unaided and gradually increase the distance in preparation for the Improver level. The maximum number of swimmers per Adult Beginner class is four.
