Swim training fins have many useful benefits, including use in physical rehabilitation, aqua aerobics, fitness swimming and competitive training. Using a smaller training fin provides added resistance without overloading the muscles joints, ligaments and tendons used in water exercise. Many fitness and competitive swimmers use long scuba/snorkel fins as a training aid. Because the center of effort in a long fin is forward of the foot, the excessive blade area and displaced center of effort may cause early fatigue or cramping, and encourage a "pedaling" motion different than that used in a flutter kick. The concept of the short training fin was conceived to bring the center of effort back to the foot, increase leg strength, and allow a swimmer to train with a kicking motion that is the same as the flutter kick without a fin.
