Why is weight training necessary?

Though my form still needs a lot of work, I am considering starting strength training in the near future, since I have read about how it can help swimming speed, form, etc. However, I am still struggling with the idea of why strength training is needed. Lets assume that lifting a certain weight in a certain way improves a core muscle, which will help steady my posture (?). Now assuming I don't weight lift, but instead try to hold the proper posture (high elbow, etc.) for a long period of time, and gradually increase the time I do that over weeks and months, won't those muscle(s) automatically improve? It seems to me that intuitively the proper muscles would gradually get stronger in order to adjust to the frequent usage - that way the exact muscles I need would get stronger, instead of having to train a large array of muscles that have a relation to swimming. What am I missing?

  • I hate cardio! That said, I did a moderate cardio class on Wed. I swam Thurs AM before my thighs started killing me. My stroke count, which had been deteroirating during workouts, stayed level and I was able to keep it through the workout. Legs still ache, but I swim tomorrow and will do the cardio on Mon.
