Arm Brain: A Unique School of Disc Golf Term:

This post is one of a series that explains terminology unique to — or at least originated by — School of Disc Golf. Each term in the series was created by me, many spontaneously during a private lesson as I searched for a new way to explain something to a client.

Think Different

For the first one in the series, I picked a biggie. Those who are familiar with Three Paths to Better Disc Golf know one of those paths involves having a predetermined philosophical approach to the game. Broad concepts a player can use to guide smaller decisions and lead to their best chance to score well.

When I wrote that book I was thinking mainly of strategic concepts, but with thousands more hours of hands-on disc golf instruction under my belt since then, I realize it applies to technique and mechanics as well. Perhaps more so.

“Arm Brain” is a term I use to describe an incorrect mechanical approach most people instinctively take to backhand driving in disc golf. In the same way that early science before Copernicus thought the earth was the center of the universe, most players treat their arm as the core of their drive.

It isn’t, of course. I use other terms in my lessons, like Nucleus, Center Pole Position. Asymmetric Timing, and 180-to-Zero to explain the difference between throwing with the entire body vs. throwing with arm only— why the literal throwing arm plays a relatively minor role in determining whether a player has a figurative Big Arm.

How arm brain came to be

One day during a 1-on-1 lesson, I noticed how my client was successfully achieving the timing and balance we wanted during drills, throwing with the right muscles from the right position, and achieving the results I promised would come. However, a trend developed where after a good throw he would often follow it up with one that were complete mis-throws.

After the pattern became clear, I asked him to describe his thoughts as he set up for the next throw after an especially successful effort. Each time, he described watching the good drive fly, feeling excited about the accomplishment, and wanting to see if he could throw the next drive even further.

Since Sports Psychology 101 is based on “Focus on what you’re trying to do, not what you’re wanting to accomplish” I figured his thoughts had triggered the muscle memory from thousands of Frisbee throws. To explain my thoughts, I mused that he had allowed Arm Brain to enter the realm, kind of like saying Beatlejuice one too many times.

The teaching point was this: It is always a good idea to focus on what’s right in front of you in sports, especially when you’re working on developing a new skill. Thinking about the new mechanics in particular helps prevent “Arm Brain” from jumping in and saying “I can do that!” when you think only of intended results.

Arm Brain can also rear his head at much later stages, as well, in times of mental and physical fatigue or wandering focus. Good driving form takes some work, and if you’re not focused on executing that work Arm Brain can jump in and say “Let me handle this one. It’ll be easier.”

predetermining factors of arm brain

Since that lesson when I made up the term, I broadened the use to describe a related group of reasons why some people have a hard time learning the unique mechanics that are key to throwing as far and accurately as one’s peers Here’s a quick run-down of those reasons:

• Familiarity with tossing a Frisbee- Think of the stance you assume to play catch with a Frisbee. Your brain is likely very familiar with that stance and the action that follows, and comfortable with its ability to execute that action
• The “Big Arm” label- This popular misnomer only reinforces the other reasons
• Proximity to the hand- The hand is important because it holds the disc, right? Therefore focus should be on the thing connected to the hand— or so goes the logic.
• Eyes on target- The same power-sapping position that is comfortable and familiar for a Frisbee toss is also the posture that provides a clear view of the target with both eyes before throwing— something that isn’t possible at the beginning of a proper full-power drive.

how to outsmart and outwit arm brain

You gotta know he’s lurking. You gotta know how to spot him. And you gotta know how to deflect and defeat him.

If you had to work to learn proper driving technique (or are still in the process) vs. it coming naturally right away (and sometimes even then), Arm Brain is lurking. Don’t doubt it.

If you catch yourself thinking about wants and needs rather than mechanics as you set up for shots, and your throws start to lack their normal explosiveness and carry, Arm Brain has likely infiltrated your camp. The best way to banish him is to purposefully focus on elements of your mechanics that most starkly contrast a Frisbee throw, things I focus on in sessions with my clients.

One of my favorite mantras to banish Arm Brain is “Aim with the Body, Throw with the Body,” another unique School of Disc Golf term phrase. Maybe we’ll cover that one next!
