How to do a bar muscle-up
A bar muscle-up takes you from hanging below a pull-up bar to supporting yourself above it in one movement. It is one of the big gymnastics milestones in CrossFit. Strength helps, but most of it is timing: a good swing, a strong hip drive to the bar and a fast turnover.

In short
- Hang with a full grip and build a controlled swing.
- Arch with your chest through, then kick to a hollow and drive your hips to the bar.
- Pull the bar towards your hips as you lean over it.
- Turn over fast and press to straight arms on top.
Step by step
Grip and start the swing
Hang with your hands just outside shoulder-width and a full grip. Start a small swing from your shoulders, not your knees.
Arch: chest through
At the back of the swing, push your chest through your arms with your legs behind you. This loads the movement like a bow.
Kick to the hollow
Snap your legs forward and down into a hollow position, keeping your arms straight. This is where the power for the muscle-up comes from.
Drive your hips to the bar
As your legs swing up, drive your hips towards the bar and pull it down towards your hips with straight arms. Keep your legs long rather than tucking your knees.
Turn over fast
When your hips reach the bar, lean your chest over it and bring your elbows back quickly so your shoulders get above the bar.
Press out on top
Once your shoulders are over the bar, press out to straight arms in support, then lower yourself back under with control.
Common mistakes and how to fix them
- Bending the arms too earlyKeep your arms long until your hips have driven to the bar. Pulling early kills the swing.
- Tucking the kneesLong legs give you a longer lever and more height. Keep your legs long and drive your hips up to the bar.
- Chicken wing (one arm at a time)Get your chest over the bar before you press, and turn both elbows over together. If one arm lags, build more height first.
- No hollow positionWithout a strong kick from arch to hollow there is nothing to drive your hips up. Drill the swing on its own.
Drills to build it
- Kip swingsPractise the arch-to-hollow swing for sets of 5 to 10, keeping your arms straight and the swing controlled.
- Hip to bar swingsFrom the kip, drive your hips to touch the bar with straight arms, then drop back. This is the engine of the muscle-up.
- Banded or jumping muscle-up transitionsUse a band or a low bar to practise the turnover and press so your body learns the path over the bar.
Filming it for a form check
Film from the side so the whole bar and your feet are in shot at the bottom of the swing. Stand far enough back to catch you on top of the bar. Good light helps, and keep the phone still, propped up or on a tripod.

Questions
How many pull-ups do I need for a muscle-up?
There's no magic number, but strict chest-to-bar pull-ups and solid dips make it far easier. Technique closes most of the gap.
Bar or ring muscle-up first?
Most people find the bar muscle-up easier to learn because the bar doesn't move. The ring version needs more strength through the transition.
Why can't I get high enough?
Usually a weak hip drive or bent arms in the swing. Work on hip to bar swings before adding the turnover.
