🏊‍♂️ At the 1948 Olympics in London, the men’s 200m #breaststroke marked a turning point in swimming techniques. Athletes started using 🦋butterfly-style arm motions alongside the standard breaststroke kick, giving them a distinct advantage. This innovation laid the foundation for the modern butterfly stroke, which FINA officially recognized as a separate discipline in 1952. #swimming | Retro Swimming
