Wow Your Friends : Improve Running Speed

You want to run with your friends, but you know that they are much faster than you. They've invited you for a jog, but you don't want to fall behind the group and end up taking a cab home.

Hook a rubber band from your ankle to your big toe. Twist the band once so that is looks like a figure eight.

Having the extra tension of the band around your foot allows it to flex further than it normally would. This increase in flex will allow you to have a greater push off the ground as you run. You will find it easier to run faster, longer.
