Today studies show that frontcrawl also know as freestyle is the best stroke for speed although every body has his own style.. Any why i wanna know what do you think witch one is the best stroke? Butterfly is good for exercise and strength. Breast stroke can be good for the back but it can heart it to.. Front crawl if thing is really the best and back crawl can be healthy too, but i don't like to swim it much..
