aka “The Piker”: Muted hips causes upper body flaws and excessive arm and shoulder use, which tends to result in the piker reaching their arms forward in order to get the rope to pass their toes.
Concentrate on your heels striking your butt when you jump! Though the eventual goal of proper jumping is to have your knees and hips fully extended, in order to break this bad habit, we advocate trying to kick your butt with your heels until you “break the pike”.
Think of your legs as being a door. By kicking your butt with your heels, you’re opening the door and allowing the rope to come through. (Associations like this are corny, but they work!)
Fully extend your hips! Pikers tend to reach their behinds backwards when they jump, leaving a muted hip in the bound. Concentrate on pushing those hips forward when jumping! The combination of pushing the hips forward and the feet slightly back will help find proper jumping form.
