FYI, let me start by saying at the outset, you don't have to shave your legs and armpits. If you decide you want to there are some things you need to know first. Kid's Health has some interesting information. This video was made by Gillette so they're promoting their products. It's American so they refer to shaving cream as shaving gel. If you have sensitive skin it can help to shave in a downward motion as opposed to upwards as shown in this video.
