Swimming
Only upper body
Depends on what you do
Not really
You still sweat, you still ache if you don't stretch afterwards
Again, depends on what you do (Olympics had a 1500m race, that's 100m short of a mile)
Running
Once again, depends on what you do (see above)
And lungs, plus, running builds a natural antioxidant system
Is sweat really that bad?
Track girls are freaks (In a very, very good way)
Hey, smart one, Swimming works EVERY muscle in the body, not just the upper body, shows how much you know about swimming.
doing 4 years of swimming and 3 of track and field, I have to say.
Both are pretty tied.
Look at it like this, in running, you need to know how to breathe/stride. No one Focuses on this as much as you focus on technique in swimming, and the best way to increase strides and steady your breathing is by training hard.
Then you have Swimming, if you have the technique down, your pretty much good to go, but its a lot harder to the equivalent of running laps in the water.
I think they are both hard in their own way, some people have a talent for running, as others have a talent for swimming.
