This is a trick that will make running 6 times more effective.
Run backwards when you are jogging. There are reasons why this is more effective than ordinary running. 100 steps backward are equal to 1000 steps forward. 1 lap of the backward track is equal to 6 laps forward. Not only these, but it also works the muscles without harming the joints. It reduces pressure on the knee joint. It also develops borderline vision. It exercises your brain. It helps you maintain your posture. Practice this only on an even surface. This surface can be a trade mill if you want.
