I've said before that I am a sucker for videos of big jumps..... (remember this one?) Anyway, Mark recently posted a good article on Plyometrics..."to make you fitter, faster and stronger"
He includes some the video above of extreme bounding:
Starting from a gentle jog, push off the ground with your left foot and bring the leg forward with knee bent and thigh parallel to the ground. Extend the right arm forward as the left leg comes through and swing back as left foot touches floor. Then the right leg drives forward, with opposite arm extending and then flexing back. By keeping foot strikes (that is, the time that your foot is in contact with the ground) to a minimum, you will execute a series of quick, long strides that attempt to cover as much distance as possible
