Target Muscles
What muscles does the one-arm pull-up work?
One lat and one biceps handle your entire bodyweight, which is why this remains rare even among strong athletes. The demand on the biceps and the elbow tendons is extreme, and the brachialis takes a large share. Grip is a genuine limiter: a single hand has to hold everything. The core and obliques work hard to stop rotation, since your body naturally wants to twist towards the working arm. The scapular stabilisers on the working side control a load they never see in two-arm work.

How to train it
One to three reps per arm, and treat every rep as a maximal effort. Expect years rather than months. The path runs through archer pull-ups, then one-arm negatives with a slow controlled descent, then assisted work holding a towel or the opposite wrist with the free hand. Two sessions a week is plenty. Train grip separately - dead hangs and towel hangs - because it will otherwise be the thing that stops you.
If you are stuck
Attempting this too early is the most common mistake and the one that injures elbows. The connective tissue adapts far more slowly than the muscle, and golfer elbow from premature one-arm work can cost months. Earn the prerequisites first. Momentum is the second issue: a rep started with a swing teaches nothing. Neglecting grip training is the third - many people have the pulling strength before they have the hand strength, and the fix is dedicated hanging work rather than more attempts.

Most people need 1-3 years of dedicated training. Prerequisites include 20+ strict pull-ups and solid archer/typewriter pull-ups. It is one of the hardest bodyweight skills.
What is the progression to one-arm pull-up?
Start with weighted pull-ups, then archer pull-ups, typewriter pull-ups, assisted one-arm (finger assist), negatives, and finally full one-arm pull-ups.
