Stop Saying 'Bend Your Knees' – The Science of Better Coaching Cues

I'm going to be honest: if I had a dollar for every time I've heard "Bend your knees!" in an African gym, I'd have funded half the courts on the continent by now.

And I've yelled it too.

But the more I dove into motor learning science — especially the work on attentional focus and the Constrained Action Hypothesis — the more I realized something uncomfortable:

A lot of the "helpful" things we shout are actually making players worse.

Not because we're bad coaches.
Because we're aiming our words at the wrong place.

This article is about that.

The classic scene: "Elbow in!"… brick.

Picture this:

We're in a crowded gym in Luanda.
Two teams are running 5v5. A 16-year-old steps to the line for free throws.

He misses short. I hear a coach from the baseline:

"Elbow in! Bend your knees! Follow through!"

Next shot, the kid is basically doing algebra in his head:

• "Elbow… where is it now?"
• "Knees… how much bend?"
• "Follow through… was that enough?"

He shoots, thinking about three body parts at once.

Brick again.

What happened? Did he suddenly become a worse shooter? Of course not.

His attention moved from the outcome ("send the ball through the rim") to a list of body parts ("elbow, knees, wrist"), and that alone can be enough to disrupt the automatic control that his nervous system was trying to build. This is exactly what the Constrained Action Hypothesis describes: focusing internally on your movements interferes with the unconscious processes that normally control skilled motion.

Let's break that down in simple terms.

Internal vs External Focus — in plain language

Motor learning research, especially by Gabriele Wulf and many others, has spent over two decades testing one simple question:

"Where should an athlete put their attention while moving?"

Two basic options:

• Internal focus – attention on body parts or muscles
  • "Extend your arm."
  • "Bend your knees."
  • "Keep your wrist straight."
• External focus – attention on the effect of the movement on the environment or implement
  • "Reach for the front of the rim."
  • "Push the floor away."
  • "Send the ball through the middle of the net."

Across many sports and tasks, the pattern is incredibly consistent:

An external focus leads to better performance and better learning than an internal focus — across ages, skill levels, and types of skills.

Why?

Because when a player focuses internally, they start trying to manually control every little piece of the movement. That "constrains" the system — their movement becomes stiff, slow, and less efficient. With an external focus, the brain and body can self-organize more naturally and automatically.

In other words:

• Internal focus = "joystick mode" — the coach (or athlete) is trying to move each joint manually.
• External focus = "target mode" — the athlete is locked on the effect they want, and the body organizes itself to achieve it.

Meta-analyses and reviews show this isn't a small effect. External focus consistently outperforms internal focus for both immediate performance and long-term retention.

Does this apply to basketball?

Yes — and not just in theory.

Studies on basketball free throws have repeatedly found that instructions and cues which direct attention externally (e.g., on the rim or ball flight) improve accuracy more than internal focus ("bent knees, elbow angle") or traditional "technique" instructions.

So when you shout "Elbow in! Bend your knees!", you're not just being old-school — you might be actively lowering the chance that your player hits the shot.

Our African reality: noisy gyms, many players, many languages

Now let's layer this science onto what we see daily in African basketball:

• 30–40 players on one court
• Constant noise (music, other teams, whistles)
• Mixed ages and levels
• Multiple languages in one session (Portuguese, Lingala, Wolof, Arabic, isiZulu)
• Very little time with each player

In that environment, long technical speeches about joint angles don't just fail scientifically — they fail practically.

That's why I like external cues so much for African contexts:

1. They're shorter and punchier.
   • "Hit the back of the rim."
   • "Chase his hip."
   • "Touch the glass high."
2. They translate better across languages.
   • Visual metaphors ("cookie jar," "push the floor away") give the player an image, not a paragraph.
3. They fit chaos.
   • In a loud gym, a one- or two-word external cue survives. A full technical explanation gets drowned out.
4. They respect the player's intelligence.
   • I'm not micromanaging their body; I'm giving them a clear target and trusting their system to figure it out.

So if you coach in Africa, this isn't "nice to have." This is a competitive advantage you can implement immediately, with zero equipment.

The "Joystick Coach" vs the "Target Coach"

Let me draw a contrast.

The Joystick Coach

• Talks non-stop.
• Uses long chains of internal cues:
  • "Feet here, elbow there, knees, wrist, shoulders, hips…"
• Tries to move the player like a video game character.
• Players look good in slow, blocked drills, but the skill collapses in games.

The Target Coach

• Talks less, but with more impact.
• Uses external cues:
  • "Shoot over the front of the rim."
  • "Slice the space between them."
  • "Hit the nail, then disappear."
• Designs good constraints and games, then uses short verbal cues to guide attention.
• Players might look a bit messy in practice, but their game performance and decision-making grow.

Most of us were trained as joystick coaches.
Our next evolution is to become target coaches.

And that starts with changing our language.

Old Cues vs Modern Cues: A Translation Table

Here's where this gets practical.

Below is a table you can literally screenshot and take into your next practice. Left side: common cues we hear all over African gyms. Right side: how I'd rephrase them using external focus and simple images.

Shooting

Old Internal Cue	Modern External Cue
"Bend your knees."	"Push the floor away." / "Jump up through the floor."
"Elbow in."	"Send the ball straight through the middle of the rim."
"Snap your wrist."	"Reach into the rim." / "Finish with your fingers in the net."
"Follow through and hold it."	"Freeze your hand pointing at the rim until the ball lands."
"Use your legs more."	"Make the ball jump out of your legs, not your arm."
"Get more arc."	"Shoot over an invisible wall above the rim."

Finishing

Old Internal Cue	Modern External Cue
"Protect the ball with your body."	"Put your shoulder between the defender and the ball."
"Extend your arm to the rim."	"Touch the top corner of the glass."
"Go off two feet."	"Land like a statue — both feet hit and freeze."
"Use your off-hand."	"Finish on the side away from the defense."
"Absorb contact with your chest."	"Hit his chest first, then float up into the finish."

Ball Handling & Driving

Old Internal Cue	Modern External Cue
"Stay low, bend your knees."	"Show me your numbers to the defense." (chest facing ahead)
"Keep the ball low."	"Keep the ball below your knees so he can't see it."
"Use your hips to protect."	"Put your body between the ball and his chest."
"Explode out of the move."	"Beat his foot to the spot." / "Win the first 3 steps."

Passing

Old Internal Cue	Modern External Cue
"Extend your arms fully."	"Hit his outside hand."
"Snap your wrists on the pass."	"Drive the ball through his chest."
"Follow through to your target."	"Make the ball arrive on time and on the shooting pocket."
"Use your fingers, not your palm."	"Spin the ball so the laces turn over in the air."

Defense

Old Internal Cue	Modern External Cue
"Slide your feet!"	"Stay in front of his chest." / "Keep your bellybutton on his."
"Hands up!"	"Show me your hands in his passing lane."
"Get low."	"Sit on the chair and don't let it disappear."
"Close out with short steps."	"Arrive with high hands, then break down just outside his range."
"Active hands."	"Keep touching the ball or his passing lane every second."

Rebounding

Old Internal Cue	Modern External Cue
"Box out with your butt."	"Hit him first, then go and get the ball."
"Jump straight up."	"Catch the ball at its highest point."
"Chin the ball."	"Bring the ball to your chest and make it disappear."

You'll notice something:

• The right column is easier to feel, imagine, and translate.
• The cues are about targets, space, and effects, not about "knees/elbows/wrist."

That's the whole point.

How many cues? When do I talk?

Even the best cue becomes useless if we spam it.

Here's how I try to manage my own coaching language:

1. One key cue at a time

In a drill or SSG, I decide:

• "What is the one thing I want them to attend to right now?"

Then I build a short external cue around it.

Example:

• SSG: 3v3 advantage, kick-out to corner.
• Goal: better catch-to-shoot rhythm.
• Cue: "Catch → rise." or "Catch already facing the rim."

That's it. Not:

"Bend your knees, catch on the hop, hand under the ball, elbow under the ball, snap your wrist, hold your follow through…"

2. 80–20 rule: external > internal

As a rough guideline for myself:

• ~80% of my cues are external.
• Up to 20% can be internal in special cases:
  • Early-stage mechanics change,
  • Injury rehab,
  • A very specific, temporary tweak.

And even then, I try to return to external as soon as possible.

3. Use questions, not just commands

Questions automatically shift attention outward:

• "Where did your miss go?"
• "What did you look at before you shot?"
• "Where was the space on that drive?"

Now the player is exploring effects, not obsessing over elbow angle.

Where internal cues still have a place

I'm not saying we must ban every internal cue forever. That would be its own kind of dogma.

There are moments when an internal focus can be useful, especially in:

• Beginners who don't even know where the ball should roughly be in space.
• Rehab or return-to-play, where very specific positions matter for safety.
• Very short, "reset" instructions:
  • "Stack your feet under your hips again."
  • "Relax your shoulders."

But even there, the research suggests that long-term learning is better served when we return quickly to external cues.

So my approach is:

1. Use a brief internal cue to "wake up" awareness if absolutely necessary.
2. Immediately wrap it inside an external cue again.

Example:

• Internal (short): "Relax your shoulders."
• External (main): "Now just throw the ball through the rim like a dart."

How to start changing your language this week

Here's a simple plan you can implement in your next 2–3 practices.

Step 1 – Awareness: catch yourself

Next session, don't change anything yet. Just listen for your own:

• "Bend your knees."
• "Elbow in."
• "Hands up."
• "Slide your feet."

Make a small mental or written list after practice.

Step 2 – Translate 3–5 of your favourite cues

Take 3–5 of your most common internal cues and write external versions, using the table above as inspiration.

• "Bend your knees" → "Push the floor away."
• "Elbow in" → "Send the ball straight through the middle of the rim."
• "Hands up" → "Show me your hands in the passing lane."

Step 3 – Test in a small-sided game

Pick one SSG or drill and consciously only use external cues for 10–15 minutes.

Notice:

• Are players smoother?
• Are they less stiff?
• Do they self-correct more on their own?

Step 4 – Ask them

After the segment, ask:

"When I said X, what did you picture in your head?"

If their answer is a clear image or effect ("I saw the ball going over an invisible wall"), you're on the right track.

Final thought: changing drills was step one — changing words is step two

A lot of coaches reading this blog have already taken the step away from:

• endless 3-man weaves and cone mazes

…and toward:

• small-sided games,
• constraints,
• decision-rich environments.

That's huge.

But the science is clear: if I still coach those modern drills with old internal cues, I'm only doing half the job.

The drill is the hardware.
Your coaching language is the software.

In African gyms — noisy, crowded, multilingual — this matters even more. The right three words at the right moment might be the difference between a stiff, paralyzed athlete and a smooth, confident one.

So next time you feel "Bend your knees!" coming up your throat, pause for half a second and ask:

"What's the effect I really want here?"

Then coach that.
