I am a swimmer, especially a butterflyer. I got a weight lifting set for Christmas, but I'm not entirely sure how to utilize it for butterfly, or even swimming in general. I read up on these questions,
What type or amount of weight training is beneficial for a beginning swimmer?
What set of dry-land exercises can I perform that would be equivalent to swimming?
and browsed the internet, but I figured I'd ask it here for this specific stroke. What kinds of exercises (not just weight lifting) and stretching can help supplement butterfly?
Also, what muscles should I focus on working out?
Thanks for any advice!
