Breaststroke
The slowest stroke but also the first of the strokes invented. its modelled of how a frog swims, it is also one of the easiest strokes to learn but one of the hardest to master. quite alot of people start out with a basic form of breaststroke when they start swimming because it is easy to learn and not particulary tiring. breastroke has been around for hundreds if not thousands of years. also when swimming competitions were held in history the stroke that was often done was breastroke because it was considerd proper where as freestyle was considered barbaric. the breastroke kick looks alot like a frogs kick and is where most of the power comes from unlike freestyl or backstroke. also an important part of breastroke is making sure to glide afer each stroke to give your body the ability to go forwared and to recover before the next stroke.
