How to Throw an Axe
Keep feet planted the entire duration of your throw, any footing should be solid, stable, and balanced.
Moving your entire body. Head, feet, arm, hand, and axe, directly toward the center of the target during your throw can significantly reduce your margin of error. An unsure stance starting out can mean correcting your balance when you begin your throwing motions.
Know your starting distance. Ideally, your release will be with your feet as close to the 12 foot line as possible.
THE GRIP ON YOUR AXE CAN MAKE ALL THE DIFFERENCE
The most used grip by the top throwers is a lighter grip, toward the mid to end of the palm. For very fast throwers a stronger grip is usually unavoidable. Although there are examples of accurate fast throwers, strongly consider trying a more finessed throw if accuracy is your goal.
If you’re having trouble with vertical inaccuracy in your throw and you are gripping the axe like a hammer, there are a few likely reasons.
Stronger, full hand wraparound grips can be highly influenced by the release point.
A light grip that almost releases itself is more ideal, and more forgiving for slight errors. This takes practice and experimentation to find but can quickly surpass the accuracy of a strong grip.
RELAX ARMS AND SHOULDERS IN YOUR THROW SETUP
Simply relax the shoulder(s) for the setup before the throw movements. It is easy to tense up your shoulder or shrug inadvertently before you even start your throw. Flaring your elbow can also skew your throw, making an accurate throw more difficult and possibly striking the target at an angle which may result in a drop.
The reason this makes a difference is that without fully continuing the forward motion after the release, and instead thinking about ending the throw, you may inadvertently abbreviate some or any of your motions before the axe leaves your hand(s).
You could let go early and throw high, introduce too much spin and over-rotate, stop your arm early which can throw the axe off left or right, power reduction resulting in a drop, or drop your arm early and throw low.
