I started with my standard back day warm up.
200 band pull aparts, and 5x5 assisted pull-ups
I do these with a hoodie and sweats on; It seems to be the only way I can get my lats working right.
Work
Wide grip lat pulldowns with tsunami bar, 120 lbs for four sets of 25
Chest supported rows with a plate and a quarter, for four sets of 25
Chest supported DB rows, 30 lbs for two sets of 50
Single arm lat pulldowns 70 lbs for four sets of 25
Back extensions, four sets of 25- I did these for speed.
