Everyone - thanks again for the informative posts. It has certainly cleared up some misconceptions on my part. I guess chins DO hit the lats quite well (of course, dependent upon form). They were so effective on biceps for me that I thought that the lats weren’t being majorly stressed.
I guess I’ll continue what I was doing before. Rows (which are more of a mid back exercise for me) and chins one day, deadlifts and chins the other. Using pullups on tabata day.
That is, until its time to switch around again
