Sam Lavery tackles the thorny cricket subject of "chucking".

For many, working with fast bowlers can be daunting. While the knowledge that’s out there is gradually improving, the challenge of working with a bowler who may or may not have developed a “chuck” is a step too far for some.

Let's see if we can help with that.

Let me ask you something; how much better a bowler would you be if you could hit a perfect line and length?

It's a challenge that takes a lifetime to master, and a road that is littered with distractions.

One of the big coaching challenges is developing the athleticism of fast bowlers.

It’s the nightmare for all bowlers: Getting suspended for an illegal action when you have made it into international cricket.

Imagine how it felt for Brian Vitori, Zimbabwe left arm seamer, who was assessed in February 2016 and found to have gone beyond the 15 degree allowed limit for bowlers. He was suspended immediately.

Science has proven a way to take your cricket to the next level using a "feedback loop" at training. Bowling with this loop will allow you to quickly improve your cricket, take more wickets, bowl faster and improve your accuracy. All while at nets.

Ever wondered how the best bowlers hit their yorkers so well and so often? Use this simple drill to help you bowl yorkers with pinpoint accuracy.

Sam Lavery is Cricket Professional at Portsmouth Grammar School in England. He is a co-host of the PitchVision Cricket Show. In this column he has a drill to make nets better.

One of the regular net drills Portsmouth Grammar School is the “zonal” net.

It was no surprise to me that Gloucestershire CCC had a renaissance in One Day cricket in 2015 after being in the doldrums for so many seasons. The catalyst for change was their Assistant Coach, Ian Harvey. He brought innovation and planning to the side.

Stuart Broad recently went to the top of the ICC Test match bowling rankings after capturing 6-17 in England's emphatic victory at The Wanderers. Stuart has been England's best line bowler for years.

And he achieves this with a front arm that pulls away to the offside of the right handed batter.

But hang on a minute.

Isn't the front arm our "rudder"? The thing that we use to aim with?

This is a brilliant, simple trick for bowlers to get a big hitting batsman away from the strike if you are struggling to get them out.

Hit the thigh pad.

This trick works best for seamers who naturally angle the ball into the batsman, but it can work for anyone. Your aim is to bowl a ball that, after pitching, will hit the batter on their thigh pad.

Why?
