4) Heel kicks: Standing, kick your right heel towards your butt and then repeat on the left side.
5) A-skips: Skip forward with a nice rhythm while driving your right knee up to be even of higher then your hip while pushing all the way through your toes. As you alternate legs strike the ground with the balls of your feet.
6) Tin soldiers: Walk forward keeping your back, legs and arms straight. Flex your toes as you lift your leg straight out in front of you. Reach your arm forward as you step and try to let your toes touch your hand.
