Perhaps I am just a mouth breathing, knuckle dragging neanderthal, but I fail to discern any particular value in the set I was given this morning. 10 times through: 25, 50, 75, 100 on 1:05. Odd sets freestyle, even sets stroke (25 fly, 50 ***, 75 back, 100 free) on 1:15. There is no connecting thread of interest or challenge in any of the components here, other than to make a 100 free on 1:05 five times, spaced out by a bunch of filler. Kind of a weak argument in a 2500 yd set. I got out after 4 sets, disgusted or frustrated, I'm not sure which. Coaches, is this what you are giving because you are afraid people will be too bored with 10 x 100s? Or would you rather they get out early, knowing that you will not change because the "book" says this is a good workout?
