Chin-Up
A pull-up variation with supinated (underhand) grip that places more emphasis on the biceps while still working the back.
Short answer
Chin-Up: a beginner bodyweight exercise for the biceps and lats. You need a pull-up bar. A typical target: 3 sets of 6-12 reps. If it is still too hard, start with the easier variation, “Band-Assisted Chin-Up”. Once it feels easy, “Weighted Chin-Up” is the next step.

Target Muscles
What muscles does the chin-up work?
The underhand grip puts the biceps in their strongest position, so they contribute far more than in a pull-up - this is the best bodyweight biceps builder there is. The lats still do the bulk of the vertical pulling, but with the elbows tracking closer to the body the lower fibres are emphasised. The forearms work throughout as grip, and the rear deltoids assist at the top. Because the biceps help so much, most people can do several more chin-ups than pull-ups, which makes this the better first vertical pull to learn.

How to train it
Three sets of 6 to 12 reps, two or three times a week. If pull-ups are still out of reach, build here first: the extra biceps contribution means you will get your first rep sooner, and the lat strength carries straight over. Progress to 12 reps, then add weight. Alternating chin-ups and pull-ups across the week covers both the biceps-dominant and lat-dominant patterns without extra volume.
If you are stuck
Swinging is the most common fault and usually starts when the set is already near failure. Cross your ankles behind you and squeeze the glutes to make the lower body one rigid unit. Partial range is the second issue - going only to eye level rather than getting the chin clearly over the bar cuts out the part of the rep where the lats work hardest. Letting the shoulders shrug up towards the ears at the bottom takes the lats out of the movement entirely; pull them down before each rep begins.

Chin-Up questions
What is the difference between chin-ups and pull-ups?
Chin-ups use an underhand (supinated) grip and emphasize biceps more. Pull-ups use an overhand (pronated) grip and emphasize the lats more. Both work the back effectively.
Are chin-ups easier than pull-ups?
Yes, most people find chin-ups easier because the biceps can contribute more to the movement. This makes chin-ups a good stepping stone to pull-ups for beginners.
