joint click while weight lifting

I am 40 y.o (female)and just started lifting weights (upperbody)I'm sure I'm moving properly, but I get a click or crack in my shoulder (one side only) every time I do a rep.  Also get periodic cracking in knees.  Do you know what causes this?  Should I keep working out?  (I really need to!)  Thanks!

This is called crepitus and often times may not be any problem at all especially if you dont have any pain. If this is happening in your shoulder when doing a shoulder press, I recommend lifting only to a 90 degree angle this may help ,decrease the amount of crepitus you hear and feel. As you build muscle you are helping support the joint more so it is always impotant to exercise. But if you ever feel any pain, stop what you are doing and consult a professional

what if the cracking only happens after i workout? after a couple days of not working out it seems to partially go away, still crack, but not nearly as much. also my wrist cracks after one incident at the gym, but this one used to hurt, but now doesnt when it cracks. however both the cracking in my shoulder and wrist hinder my ability to get the full extent while either working out or during activities(such as bowling)

i am only 18.
