A NEW Page!

This DrillsĀ page is thanks to Warrior Freya. She asked what my drills were, as she was having problems finding the original posts that described them. It then occurred to me that having a page listing my drills might be easier for people who read a Rundown saying that I did a drill, but not what it was. How will they know if it is a hard drill or if I was just lazing through my week? (that does happen, you know) Also, some people might even want to try these! I gave credit to the sources that gave me these drills, but you may notice that I was happy to modify them for myself. If you want to try them, feel free to modify them for yourself and your level. Walk instead of run. Go shorter distances or times*. And tell me how you liked them!

*just be sensible and don’t hurt yourself!

Why did we need to work on breathing again?

So a recent post discussed ways to breathe better while exercising. But did I mention why that might be important?

If you are going to be exercising for more than a couple of minutes, your body needs to get oxygen to the muscles or the muscles will stop working. Just how much oxygen your muscles will use depends on two processes: getting blood to the muscles and extracting oxygen from the blood into the muscle tissue. Your working muscles can take oxygen out of the blood three times as well as your resting muscles. Your body has several ways to increase the flow of oxygen-rich blood to working muscle:
increased local blood flow to the working muscle
diversion of blood flow from nonessential organs to the working muscle
increased flow of blood from the heart (cardiac output)
increased rate and depth of breathing
increased unloading of oxygen from hemoglobin in working muscle
These mechanisms can increase the blood flow to your working muscle by almost five times. That means that the amount of oxygen available to the working muscle can be increased by almost 15 times!*
