Suppose you’ve been playing for a while and you’re thinking about how you might improve your game.
Here’s a suggestion. Pay attention to your left arm. (That is, to your non-throwing arm. If you’re a leftie, pay attention to your right arm.)
Here are some pictures. In each picture, look at where the player’s left arm is.
As you can see, these players aren’t crouching or bent forward. (We’ll talk about crouching later.) Their torso is basically upright. They keep their left arm straight. As they throw, they swing the left arm back, extend it back behind the torso, and hold it there while swinging the other arm to throw the boule.
The left arm, extended back, is a counter-balance for the right arm as it swings forward to release the boule.
If you don’t extend your left arm back this way, you will be unbalanced when you throw. As you follow through, you will find yourself almost falling forward. To compensate and to maintain balance, you will have a tendency to lift your left foot off of the ground. Which is, of course, a foot fault.
This is fixable. If you find yourself lifting your left foot off of the ground when you throw, it is an indication that that you aren’t using your left arm to provide balance. Change your form— stand up straight and start using your left arm for balance— and you’ll lose the need to raise your left leg.
As you practice your form, there are a couple of things that you should watch out for. You may do them without even realizing it. Ask a friend to watch you and give you feedback on your form. Or even better yet, ask him or her to take pictures of you, so you can look at yourself later.
One thing you should watch for, and try to avoid, is putting your left hand in the small of your back.
A lot of beginning players instinctively imitate what they see experienced players doing. They see that their left hand should be behind them, so they hold it against the small of their back.
This is better than nothing, of course. It’s a step in the right direction. But when the arm is so close to your body it doesn’t provide the amount of counter-balance that you’d get from fully extending your arm back behind you.
When players aren’t using their left arm for balance, many instinctively and unconsciously go into “the crouch”. This is where you keep your balance by sticking your butt out. In order to get the butt back far enough, the player has to crouch down. Crouching can be difficult, so the left hand usually ends up on top of the left thigh to add support and stability.
The crouch isn’t inherently bad. It can be a useful stance when you want to point a long, low, rolling boule. But you don’t want the crouch to be your ONLY way of throwing a boule. That would be really limiting. You can’t lob or shoot from a crouch. That’s why it’s better not to crouch. Stand up straight and use your left arm for balance.
