SIGNS YOU’RE DOING IT WRONG

Your hips are sagging This is more likely to be a problem when you’re up on your toes, and is a sure-fire sign your core isn’t fully engaged. Focus on squeezing your abs and your glutes to keep your body in a straight line from your head to your heels. You’re swaying or rotating your hips as you tap each shoulder

It’s a common mistake with this move. To avoid making it, focus on keeping your hips level. Imagine you’ve got two headlights beaming out from your hips and you need to keep them focused on the floor. Weird, but it works.
