Pull-Up — CrossFit Technique Guide
The pull-up is the single most important upper-body pulling movement in CrossFit. It develops the lats, biceps, and posterior shoulder while building the grip and core strength necessary for advanced gymnastics skills like muscle-ups and bar muscle-ups. In CrossFit, pull-ups appear in nearly every Hero WOD and benchmark workout, often in high volume. Mastering efficient kip mechanics and developing strict strength are both essential: strict pull-ups build foundational strength, while the kipping pull-up allows athletes to maintain output under fatigue. Both have their place in a complete CrossFit programme.

How to Do the Pull-Up
Grip the bar slightly wider than shoulder-width, palms facing away (pronated grip).
Hang at full extension — arms straight, shoulders active (not shrugged into ears).
Initiate the pull by depressing the scapulae (pull shoulders down and back).
Drive elbows toward the floor as you pull your chin above the bar.
Hold for a brief moment at the top — chest near the bar, chin clearly over.
Lower with control back to full extension before the next rep.
Common Mistakes
Not achieving full arm extension at the bottom — reduces range of motion and builds bad habits.
Pulling with biceps only rather than initiating with the lats (scapular depression).
Kipping before building strict strength — increases shoulder injury risk significantly.
Losing tension in the core during kipping pull-ups, causing excessive swinging.
Coaching Tips
Build to 5 strict pull-ups before attempting kipping — your shoulders will thank you.
Think "armpits to the bar" rather than "chin over bar" — this cue activates the lats properly.
For high-rep sets (Murph), sub-partition early: sets of 3-5 rather than going to failure.
Band-assisted pull-ups are excellent for building strength; jumping pull-ups maintain the stimulus when fatigued.
Scaling Options
Easier / Beginner
Band-assisted pull-ups, jumping pull-ups, or ring rows at a 45° angle.
Harder / Advanced
Strict pull-ups, weighted pull-ups (belt or vest), or chest-to-bar pull-ups.
Frequently Asked Questions
What is the difference between strict and kipping pull-ups?
Strict pull-ups use no momentum — pure upper body strength from hang to chin-over-bar. Kipping pull-ups use a rhythmic swing to generate momentum, allowing more reps under fatigue. Strict builds strength; kipping maintains workout intensity. Both are valid — strict should come first.
How many pull-ups do I need for CrossFit?
A practical benchmark: 5 strict pull-ups gives you the foundation to safely start kipping. 10+ strict is comfortable for intermediate athletes. For Hero WODs like Murph (100 pull-ups), efficient kipping mechanics and smart sub-partitioning matter more than raw max.
Why do my shoulders hurt after pull-ups?
Shoulder pain during pull-ups usually signals one of three things: insufficient warm-up, kipping before building strict strength, or not achieving full extension at the bottom. Address all three. If pain persists, consult a physiotherapist before continuing.
