The chin-up is a bodyweight pulling exercise that primarily targets the latissimus dorsi, with strong help from the brachialis and brachioradialis of the forearm, the teres major, the lower and middle trapezius, the rear delts, and the lower-chest fibers. The supinated (underhand) grip puts your biceps and forearms in a stronger position, making it a great vertical-pull builder for back width and arm strength.
Cómo hacer el Chin-Up
- 1Grip the bar with an underhand (supinated) grip, hands roughly shoulder-width apart, palms facing you.
- 2Hang at full arm extension with your shoulders active, not loose, and your core braced.
- 3Pull your shoulder blades down and back to set your back before the elbows bend.
- 4Drive your elbows down toward your ribs and pull your chest up toward the bar.
- 5Continue until your chin clears the bar, keeping your body roughly vertical without swinging.
- 6Pause briefly at the top with your shoulders away from your ears.
- 7Lower under control over 2–3 seconds until your arms are fully extended again.
- 8Reset at the bottom and repeat for your target reps.
Consejos de técnica
- Lead each rep by depressing your shoulder blades first, then bending the elbows, so the lats drive the pull instead of just the arms.
- Keep a slight hollow-body position (ribs down, glutes squeezed) to stop your lower back from arching and your legs from swinging.
- Use a full range of motion: dead hang at the bottom, chin over the bar at the top.
- Control the lowering phase — the eccentric builds strength and protects your elbows and shoulders.
- Keep your wrists neutral and grip the bar firmly to keep your forearms engaged throughout.
Errores comunes
- Kipping or swinging the legs to throw yourself up, which uses momentum instead of the lats and makes the rep both easier and less effective.
- Cutting the range of motion short by not locking out at the bottom or not clearing the chin at the top, which reduces the work done by the back and biceps.
- Shrugging the shoulders up toward the ears at the top instead of keeping them down, which shifts load off the lats and stresses the neck and shoulder joint.
- Dropping fast at the bottom and bouncing out of the dead hang, which strains the elbows and shoulders and wastes the eccentric.
- Letting the elbows flare wide instead of tracking down and slightly forward, which weakens the pull and reduces lat involvement.
Preguntas frecuentes
What muscles does the chin-up work?
It primarily works the latissimus dorsi, with the brachialis and brachioradialis, teres major, lower and middle trapezius, rear deltoids, and lower-chest fibers acting as synergists. The underhand grip also loads the biceps and forearms heavily.
What is the difference between a chin-up and a pull-up?
A chin-up uses an underhand (supinated) grip with palms facing you, which recruits more biceps and forearm. A pull-up uses an overhand (pronated) grip with palms away, which biases the lats and upper back. Most people can do more chin-ups than pull-ups.
How do I progress if I can't do a single chin-up yet?
Start with slow lowering (eccentric) reps: jump or step to the top, then lower yourself over 3–5 seconds. You can also use a resistance band looped over the bar for assistance, or an assisted pull-up machine, and reduce the help as you get stronger.
How wide should my grip be on a chin-up?
Roughly shoulder-width with palms facing you is standard and lets the biceps and lats work together comfortably. A grip much narrower or wider can strain the wrists and elbows, so keep it where your shoulders and forearms feel strong.
How many sets and reps of chin-ups should I do?
For most lifters, 3–4 sets of 5–10 controlled reps works well. If bodyweight reps become easy, add load with a dip belt; if you can't reach 5 reps, use band or machine assistance and build up.
