Moving quickly from your knees to your feet is only easy for Jackie Chan (and other action stars). But this is one stunt you can master with a little practice. Starting on your knees, contract your glutes and quads and jump to your feet in one motion, landing in a deep squat. Yelling hi-ya or whipping out your nun-chucks will earn you our undying love—which is worth the weird looks you'll also get.
Tip: Start by doing these on thick carpet or a mat and swing your arms to help you get enough momentum.
