5. Learn the three-point stance. It's the transition between sitting and standing, crucial to standing up from your deepwater start position. As you're riding on your butt, simply bend your knees and squeeze them together while bringing your feet back. Keep your ankles pointed up and place your feet in the water like training wheels on a bicycle with your butt being the tire. Your goal is to be sitting upright on your butt, arms out and feet gliding on the water, hence the three-point stance.
