Might try:
SLDL...lat's, traps..all the way down the whole chain of back muscles including the ham's and calves
Cleans/Hi-pulls.....thick upper back/traps & rear delts. Mass builder.
Rope climbing.... superior lat/back motion, though very rare now-a-days. also a bicep builder.
Chins..partials, half way up from bottom position. ..second half from middle position to the top position. Can use a lot of added weight with using a heavy belt.....builds a wide and thick back. Negative here also. Might need straps after awhile.
Chins...one arm ..negatives at first...can hold a DB in one hand after awhile.
Bent arm pullover...BB/DB...outstanding lat builder..also pecs & triceps
Straight arm pullover (sit or stand) on a lat machine. ..can try this also on a incline or flat bench facing away from the cable/lat machine.
If you desire you could do tri sets, giant sets, rest/pause, drop sets, extended SS's, etc. Good Luck.
