1. It’s not as simple as it looks... The Plank

2. How Plank Impacts your Body…

3. Scientifically Speaking… Similar to a beam bridge, the supports are at your feet and your arms. However, your stomach is like the bridge span. It is constantly affected by gravity and sags. However, when you try to hold your body straight, your core resists against the dead load of your body weight and your abs are tensed to try to keep you up longer, exercising them very well. Your back is compressed if your core is tensed, again like a beam bridge, exercising your back muscles.

4. A Comparison… This guy probably does not do plank in his spare time… This guy does plank for a living… I’M ABTASTIC!

5. Our Theorem Like a beam bridge, the farther away the supports are, the weaker the span. Therefore, the taller you are, the harder it is to do the plank. Your arm and legs are the only things supporting your body, and the taller you are, the farther apart they are and it is therefore harder to hold plank position.

6. Our Theorem Cont. This graph shows that the shorter people held plank longer.

7. In all Grades… Whichever gender was taller held the plank for less time (e.g. Abhiram v.s. Blythe : Blythe held her second run longer than Josh.)
