Hi Radha. Once we have all of the necessary permissions and assessments out of the way (which I’m assuming you have already done here) I always begin with an analysis of the sport itself and the physical requirements necessary to complete their athletic skill. In my opinion, working on lower body power would be a necessity here, as well as on rotational strength and power. There are a number of exercises available to develop each of these, and to list them without real explanation of what they are and how to use them is probably beyond the scope of an answer that I can provide here. But for me these are two areas that I would definitely work on with a cricket batsman.
I hope that this helps!
First, make sure they have a solid foundation. At the very least, they should know how to perform bench press, shoulder press, pull-ups, and squats, rows. These are your foundations upon which to build on. Once these are mastered, move on to explosive movements as Webb suggested. Also DON’T forget about plyometrics, such as overhead throw, side throws, powerful trunk rotation using a cable, alternate bounding, jump squats
