I have zero coaching experience so take this all with a pinch of salt...
When bowling, the top half of the action is out of sync with the bottom half.


As you can see in the still, the ball has been released and you haven't fully planted your front foot yet, so any energy you should generate from your hip drive/rotation is totally wasted because the ball is halfway down the pitch by the time your right hip comes round.
Compare that to these guys:



Ignore Rashid's eyes though, maybe if he looked at where he wanted to land the ball he wouldn't be a club level leggie.


If you can get your bowling arm coming over with your hip/back leg coming through then you'll become a more dangerous bowler but it'll probably take quite a bit of work.
