When i do a chin up, what muscles am i primarily using?
Asise from the bicepts & lats, there's the muscle on the back/top-side of your forearm, near your elbow. IIRC it called the pronator.
Anyway, since your palms are facing away, you'd wanna do reverse arm curls (palms facing down when holding the bar, instead of facing up). That would prolly be more helpful than regular arm-curls.
The other muscle gruop invoved, Lats (latimus dorsi, IIRC) can be strengthened by doing bent-over rows, pull downs on a high pulley/cable type machine (very similar to pull-ups or chin-ups, depending how you grip the bar). Or you can lay flat on your back on the floor, with your arms outstretched holding weights (barbell, dumbbell). Lift the weight from the floor to overhead keeping your arms straight.
Or, you can use one of those excersise wheels. Get on your knees, lean forward with your weight on the "wheel" and roll forward and back. You'll be pushing down using your lats.
You could also do some "negative" pull ups. After you do all the "normal ones" you can, get yourself in the top position. Then
slowly lower yourself back down to the usual "start" position.
Obviously, your ability to do any/some of these depends upon the equipment available to you.
