Six-hitting also requires a special technique, which the likes of Aravinda de Silva had, but a little extra muscle can help too.
Look, Arjun, even if hitting sixes mattered that much (very seldom can you take the sixes away from the scores of both sides and change the match-result) the fact of the matter is, you don't need strength and heavy bats to hit the ball for six, not if you go about things the right way.
A good backlift and a gift for timing is all you need. And, of course, the technique to play the right shots in the neccessary manner.
