You're bowling speed can drop in a just a week.

It's no good training all winter for speed, coming to the start of the season and losing the vital physiological qualities that enable you to bowl quickly. That's why understanding the timing of training is crucial if you want to stop wasting your off-season.

30% of English professional cricketers are private school educated, despite only 10% of people going through paid-education. The system works. It's a wonderful tradition.

That's a system that the Andrew Flintoff Cricket Academy (AFCA) has decided to bring to colleges with no cricketing tradition. A new scheme is set to have cricket at the centre of a fully rounded education, without the need to pay high fees.

I'm not going to lie, I wish there was a model like this when I was 16.

Kumar Sangakkara signed off his Twenty20 career with a Man of the Match performance steering Sri Lanka to World glory.

Yet entering final Sunday, Kumar was experiencing something every batsman feels: hideous batting form.

Sri Lanka had progressed to the final of the tournament despite Sangakkara scoring 19 runs at an average of 4.75. He was horribly out of form and couldn't buy a run.

We all know that feeling!

For most players, the downward spiral tends to continue, our scores remain low, our confidence is eroded on a daily basis and our emotions shift between dejection and desperation.

But this cycle did not happen to Kumar Sangakkara.

How much should you bowl?

All fast bowlers know that the more you bowl the better you get. We also know that the more you bowl, the greater you chance of injury. So every session is a balance between performance and preventing back, knee or shoulder issues.

The ECB has done a huge amount of research into the subject and have come up with a simple guideline for working out how much is too much and how much is just right: 7/4/2

Off spinners have to be clever. Moving the ball in to the right hander reduces your ability to take wickets over an equally skilled slow left arm bowler.

That means you need to be even more canny than the average spinner, and it's why you see such a variety in styles of off spin.

The big ripping offie bowls an "attacking" line outside off stump and through the gate. This is a great tactic, but what do you do to mix it up, or defeat a batsman who has your number?

So, picture the scene: an attacking off spinner who is having no luck against a batting pair. The batsmen are using their feet well to get to the pitch and drive safely.

What happens next?

You don't need to be fit to be a skillful cricketer, and you don't need to be skillful cricketer to be fit. But, both elements together will feed off each other to make you a better player.

This week's winner of the Cricket Show podcast question competition is Ahnaf. He wins a free coaching course from PitchVision Academy.

The winning question was:

"I am a 13 year old batsman. I play for my school team. We have a coach who isn't good a fixing our problems or teaching new techniques. When I am batting I stand with a wide stance. My school coach tells me to stand with the orthodox stance. I am not fast at moving my feet so I stand with a wide stance. What should I do?"

Listen to the panels answer to his question here.
