Bend your back

Bad weather can offer an advantage to the underdog in sports games. This is because of the outside elements that can prevent the top athletes from spotlighting their individual talents. Cricket is the only game where “bend your back” has a specific technical meaning. But whatdoes it really mean?
Bend Your Back: The Basic Meaning
This term is used in cricket even when the pitch is perfectly flat. For a bowler to generate spin or bounce when delivering the ball to the batsman, they must physically “bend their back” — in other words, exert extra effort. Sometimes the movement of the body helps the player to get an additional boost when throwing.
Bend Your Back: A Related Expression
The batsman has a similar expression – carry your bat. It is addressed to the last player of the team who remained in this position to finish the inning. Usually, it is always difficult for 11 numbers to maintain the physical and mental effort required to play out the 60 overs – thus the “carrying their bat” batsman are typically low scorers but earn respect for their stamina.
