Continuing the Dryland (post 4)

So since I posted my last post I've continued the basic workout that Salo had said to start with. After doing them for a couple of weeks I felt ready for what he considered to be "the next step" in perfecting and improving my swimming abilities.

What he says you do after the basic work outs is you begging to work on your abdominal and the general core of your body. He says you need to work on your core because, "If there is a weak or broken link, it can compromise the integrity of the entire chain" (Salo 90). What he means by chain is each individual body part. And if one is weak than you swimming will suffer as a whole since the one part is messed up.

How he suggested you fix your core is through a series of workouts. These range from various forms of planks in different positions. Then also doing certain types of core stretches. He says that while doing these you go through steps of beginner, intermediate, then advanced. Switching from each level is determined with how easy each exercise is for you (Salo 92).

What i was wondering though with the new things tat I've read about Salo's book do you think that being weak in one part of your body will really hamper your swimming ability or is he over reacting that part?
