Here’s another little idea to give a go if your bowling’s not going that well. One of the essential things that you need to do is get side-on in your bowling action. One of the ways that you can check this, or focus on it, is to make sure you come out of your bound with your landing foot at 90 degrees to the crease and have your leading arm raised and check to see that you’re looking over your shoulder – around the outside of your arm.
I find that this is a really useful calibrating action, as I have a tendency to start going front on when being lazy or confused about why my bowling’s up the Sawnny. This tends to help me get back on track again. Very simple and worth trying if you’re having problems.
