What are the main muscles used in swimming? (Particularly the freestyle and breaststroke)?

I know swimming is one of the best workouts you could possibly do because it works out almost every muscle in your body. But what I want to know is which are the main muscles used in say the freestyle and breaststroke forms.|||upper back, shoulders, arms, bicepts, tricepts, and quads in legs for kicking - freestyle





same for breastroke but more pecks and inner thigh and amazingly calves and shins|||pectoral muscles are big in the breaststroke|||Your pectoral muscles and your shoulder muscles are the main ones. Your upper back muscle is also very important.|||I'd say all the muscles in your thighs are very important and your biceps/triceps %26amp; shoulders, to put it simply. but' they're right, you really have to use everythihng.. the best way to strength train for swimming is by just swimming.. especially with paddles and a pull buoy for working your arms.|||Swimming is the only exercise that requires you to use all the muscles.|||all of the muscles, but mainly your whole upper body and your lungs|||there is a lot in your leg muscles because you have to kick a lot and also you have to rotate your shoulders constantly so that is a lot of work on your shoulders. also it works your hips from rotating side to side. and swimmers usually have great lung capacity because of being able to siwm without breathing a lot
