Different: The description in the link i posted is wrong. Pull-ups are done with palms facing away from you, gripping the bar at a bit more than shoulders-width apart. Chin-ups done with palms facing inwards, narrow grip hands around 15-20 cm apart. Chin-ups are slightly easier to do as you utilize more muscles (biceps, especially) with this grip. You're doing pretty good with 8 pull-ups; I think perfect-form 6 ea. is the benchmark for in-shape guys, (and minimum requirement for Marines). And I think that unlike a lot of people posting on here, you are being honest..
