It's very important to have a good back foot defence to survive at the international level where fast bowling rules. Once you see the ball short, important to rock back quickly close to the stumps, making full use of the ample space provided in the batting "box".

Get that left elbow high. And keep that head in front. Dont push too much with bottom hand keep that hand soft and closely tucked to your body.

Back foot well back into your stumps in line with the off stump. The front foot follows. Stay side on. Front elbow rises up in line with the ball. Bottom hand loose on the handle. Weight in front.
