Stand facing the center of the room with your feet about a shoulder's width apart. Bend your knees then jump up into the air twice. When you land the second time, land with your right foot in front and your left leg in back, almost as if you're preparing to start in a foot race except that your right foot is a little to the left and your left foot is a little to the right. Jump up into the air, and land with your left foot in front and a little to the right and your right foot behind and a little to the left. Repeat these steps over and over.
Stand with your feet close together and facing the center of the room. Lift up your left knee. Let your torso lean a little to the left as you kick your left leg twice to the front. Jump up and land on your left foot as you lift up your right knee, kick once to the front with your right foot, your leg fully extended. Bring your right foot back and tap it behind you and a little to the left. Jump up and switch your feet with your right foot in front and a little to the left, with left foot behind and a little to the right. When your kick with your left foot, do not fully extend your leg--unlike the kick with your right foot where the leg should be straight. When you land with one leg or the other behind, think of a lunge stretch where the front leg is a little bent while the back leg is almost straight behind you.
Start with your feet about a shoulder's width apart facing the center of the room. Bend your knees and jump up twice. When you land the second time, pick up your left foot and hold your leg bent, your foot behind you. As you do this, twist your body so that your left shoulder goes back while your right shoulder goes forward, and your left knee points to the left. Jump up again and land on your right foot, this time twisting your body so your left shoulder goes forward while your right shoulder goes back, with your left knee pointing to the right. Jump up again and land with your shoulders square and your torso facing front with your left knee pointing to the left. Repeat.
Stand facing your partner (which could be your best mate) with your right side facing the center of the room. Lift up your right leg as your partner lifts up her left. Touch your the side of your shoe to the outside of your partner's shoe, then lift up your left leg as your partner lifts up her right leg and touch the side or your foot to the inside side of your partner's foot. Do this four times. Pivot on your left foot to the left so that your left side is now facing the center of the room. Your partner pivots in her right foot and ends up with her right side facing the center of the room. Reach back with your right foot as your partner reaches back with her left and touch your feet to your partner's. Put down your right foot and reach back with your left as your partner reaches back with her right and touch feet again. Do this four times as well.
