Place your hands at your sides, fingertips touching the floor, behind your right foot. Bring your body forward over your right leg, as near to the floor as possible. A pop or crack may be heard. This indicates that you have popped your leg properly. For an even better pop, stand with your front foot back about three feet. Bend your front knee and swing it backward as far as possible. You will feel a slight shock down into your foot and ankle. This is because your rear foot is lifting off the ground. Your legs should be straight when you do this move. If they are not, correct them by bending the offending leg until it is ready to be popped. Now that you have popped your leg, return to the starting position and repeat on the other side. It is important to keep both legs straight during the pop-and-split movement so you do not injure yourself. Pop your leg every time you go through the motion of splitting into two equal parts, whether you are standing or moving around the room. Practice this movement until it is easy and smooth.
