<p>Pig planks. Neither are my favorite, so I might as well lump them together.</p>
<p> </p>
<p>There are straight arm planks and forearm planks, so it's not that one is correct and the other isn't. What does matter is your shoulder positioning in both, however. Most people make the chest concave, thinking they're working their arms and core more strongly, but that's really not the correct position for the body as a whole. If your shoulders are hunched toward the forward plane of the body more, that's bad form, regardless of whether the arms are bent or straight. I had to totally relearn how to do a plank position when I started yoga, and I realized I was so weak! Better to do it on your knees with proper form than the full position at the expense of using the wrong muscles to hold yourself up.</p>

<p>Do you see the difference? In the style of yoga I practice, we talk about the taking the top of the arm bone (i.e. where the arm plugs into the shoulder socket) toward the back plane of the body. While you don't want to have a collapse between the shoulder blades, you do want to have a natural "softening" behind the sternum (the back of the heart space, if you will).</p>

<p>Also notice the head position differences. Oh that poor girl on the left, what a neck ache she's going to have! Granted, the one on the right, her upper arms aren't perfectly vertical, but overall her positioning doesn't look as painful as the one on the left. Well, at least to me she doesn't.</p>

<p>I ran 4.1 miles in the neighborhood, relatively easy effort and kept a 9:38 average pace even for the hilly parts. Was a bit windy and on the chilly side, so I'm glad I had a Buff as an earband. Had gloves too. It's this in-between weather of upper 40s and overcast that always throws me. I really don't like being cold when I run!</p>
