Planking? Helpful with muffin tops! You betcha! It may look like a silly meme, but planking is actually really intense – and, as you'll see, there are several variations. To get your standard plank on, lie down on your stomach and keep your legs straight, then gradually lift up with the help of your toes and your hands. At this point, it looks kind of like you're doing a push up. If you can't hold yourself on your arms, you can brace with your forearms instead. Just make sure that your stomach is pulled in and your back is as straight as possible. You need to hold the position for at least 10 seconds, but if you can go longer, have at it!
