• Assistant S&C Coach at Springfield College (30-64/team)
• American International College – S&C Coach (8-17/team)
• Equinox Tier 3 Trainer (1 on 1)
• Differences & Similarities
• Nothing I say here is absolute
• This is NOT an “all or nothing” topic
• Get Better at what you do by changing how you think
• I created none of this material
• Understanding the science can yield better art!
• What’s Finalized vs. What’s Actualized
Exercise/Movement Internal
(body part)
External
(effect/environment)
Sprinting “Extend the hip” “Push the floor behind you”
Overhead Med.Ball Throw “Extend the arms rapidly” Make the loudest noise on the
wall as you can
Power Clean “Move hands and arms closer
to body” “Bring the bar in”
Snatch “Extend the hips and pull the
bar upward near your body”
“Throw the bar into the ceiling
above you”
Spreading The Floor “Shift the weight of your body
to the outside of your feet”
“Rip the floor apart underneath
you”
Neck Packing “Retract head” or “tuck chin” “Make a surprised look”
Hip Hinge “Flexing hips at waist”
“Pretend a rope around your
waist is pulling you backward”
or “look out the window”
Jumping/Hoping Focus on minimizing ground
contact time
Focus on trying to touch the
ceiling
Exercise/Movement Internal
(body part)
External
(effect/environment)
Supine Bench Throws Extending the elbows fast Trying to hit the ceiling with the
ball
Front Squat “extend hips at the top”
“pop at the top” or “the
plates/bar should rattle at the
top”
Core Work “Squeeze your abs” “Pretend like you’re about to
get punched in the stomach”
Posture “Retract and depress shoulder
blades” “Stand tall with proud chest”
Posture “Extend your lumbar spine” “Arch your low back” or “ghetto
booty”
Scap. Pushup “Protract” or “push hands into
ground”
“Push your body away from the
floor/world”
Pullup “retract and depress shoulder
blades”
“Pull your shoulder blades into
back pockets”
Dynamic Effort Deadlifts in
Powerlifting
Focus on lifting/moving body as
fast as possible
Timing how long it takes to
stand up
Deadlift Finish “get your hips through!
Squeeze your glutes!” “Midnight thrust at the top!”
Exercise/Movement Internal
(body part)
External
(effect/environment)
Pushup “Externally rotate your hands
and arms” “Screw the cookie jar on/off”
Hip Hinge “Bend at the waist” “Avoid the karate chop”
Bottom position of squatting “squeeze your hip flexors” “pinch my fingers”
Posterior Pelvic Tilt “rotate your hips upward” “pull your belt buckle up”
Single Leg RDL “move your leg backward
more” “move like a see-saw”
Positional Faults - RNT, Foam Rollers, Cones
• Demonstrated with different tasks:
– Exercises
– Agility maneuvers
– Sports Skills
– Balance
– Jumping/hopping
– Etc.
• Demonstrated with different measurements:
– Time (seconds)
– Length (inches, feet)
– Criterion (pass, fail)
– Ground Contact Times
• Demonstrated with different populations
– Male
– Female
– Beginner Athletes
– Advanced Athletes
– Patients
• Demonstrated in different situations
– Under pressure
– No Pressure
• Tons of research supporting superiority of external cueing and actual movement outcomes (see references)
• SLJ & CMJ improved in all groups but EXT grouped significantly more
• INT & CON groups produced same increase in JH
• EXT produced greater vertical ground reaction forces in DJ
• Out of SLJ, CMJ, and DJ, neither INT or CON group outperformed the EXT group
• Constrained Action Hypothesis & Automaticity
• “Consciously focusing on the movements of a motor action
disrupts automatic motor control processes that regulate
coordinated movements. When athletes actively focus and
consciously control their movements, they interrupt automatic
nonconscious motor behavior processes that normally control
movements in an efficient manner. In contrast, directing
attention externally to the movement effects allows the motor
control system to naturally regulate and organize motor actions.
As a result, movements are unconscious, fast, and reflexive.”
(Wu et al. 2011)
• Movement “micro-chokes” lead to inefficiency
• Motor Unit Efficiency vs. More Motor Units
• “High-Threshold Strategy”
• Less to think about!
• Frequency of movement feedback
– Low Frequency vs. High Frequency
– As Needed vs. Routine
• 2 Studies (Wulf et al. 2002, 2010)
– Cued externally 100% of the time
– Cued externally 33% of the time
– Cued internally 100% of the time
– Cued internally 33% of the time
• Results
– ↑ External Cues = ↑ Motor Learning
– ↓ Internal Cues = ↑ Motor Learning
– ↑ Internal Cues = ↓ Motor Learning
• 100% Externally Cued Group outperformed all other groups
on transfer test! (a different motor task)
In this case more of a good
thing (external cue) IS a
good thing.
• Verbal cueing is a critical tool (obviously).
• Coach/Trainer is the link between what's written on paper and what actually happens
• Verbal instructions can alter your testing/screening (FMS, strength, elasticity) protocols as well. Stay consistent!
• Internal focus of attention can constrain motor programs causing a conscious type of control which can cause less efficient and less reflexive movement, and decreased learning outcomes
• Very frequent external focus of attention can encourage automatic processes and reduce attentional demands that promote overall better performance.
• As I said in the beginning, this is not an all or nothing
topic.
• We’ve been doing this (good or bad) already without
knowing it
• Small vs. Big Change. Not a complete overhaul.
• Internal has a place
• “isolate to integrate”

• As trainers we are continually questioning our methods, constantly
seeking to get better at what we do.
• Understanding attentional focus, frequency, and feedback are key
components of the informational properties that make up coaching cues.
• The key is to be creative while still adhering to the science of motor
learning.
• The bridge between what you finalize on paper and what is actualized in
real life is you – the trainer.
• How you communicate the intent and how the client perceives the
training initiative determines what ends up happening. The options are
endless and hopefully this presentation gets you better at what you do.
