my tricep long head is sore from doing few sets of chinups yesterday. do chinups work the triceps, arent chins supposed to work the pull muscles or am i doing them wrong? currently i use a shoulder wide grip with palms facing me.

Hi,

One of the 3 segments of your tricep (the long head) crosses your shoulder joint, and this is probably being brought into play when you are chinning. Were you doing any other exercises that may have caused it?

Andrew.

thanks Andrew, your response is very reasonable. that might be it. the other excercises i did were bentover rolls and standing shrugs. thanks.
