Oh, what's a "power pose"? Thank your for asking, that's very convenient for the set up of this blog. 10/10 you're a great team player.
A power pose, dear reader, is either 1) crossing your arms over your chest and rolling your shoulders back or 2) standing, feet apart, with your hands on your hips.
Basically just pretend you're a suburban dad who just mowed his lawn, those mower lines are perfectly symmetrical, and you're admiring your exquisite work from the porch. That pose.
