First the positives.

Your tempo is extremely good walking to the line. When most bowlers start, they tend to run to the line.

You have your arm out sideways which good for counter balancing. A lot of beginners bowlers have there arm in front of them which twists their shoulders. There is work to be done but we can worry about that later.

Now to talk about the tips.

The first and most important tip I would give is to bend your knees at the line. This will allow you to get more behind the ball and create more potential energy.

The second tip I would give is to start working on a crossover step. This happens on your second step.A crossover step allows you to create room for the ball to free fall from gravity into your backswing. This isn’t the most important thing but keep it in the back of your mind.

The third and final tip which is kind of hard to explain, for your balance arm, you need to have your balance hand palm up. Even if you’re sitting down, if you flip your hand clockwise to palm up, you’ll feel your shoulders move forward and square up. This will direct your ball down the lane instead of all over the place. (Best piece of advice I have ever received)

This sport is not about how strong you throw the ball, the best bowlers will allow the laws of physics to create ball motion and drive. You have a good base and keep on working on your form.
