thats pretty good.
dips are purely a chest exercise for me
pull ups are more of a upper lat exercise for me with a little delt/bicep/forearm help
chin ups are primarily a bicep exercise for me, although i concentrate it that way. the lower lats are secondary for me, and a little delt/forearm help
hammer grip pull ups- i use these to target the serratus and work the forarms also
concentration has alot to do with what muscles you will work too.
