Back workout

Did this workout couple nights back with a mate...yep

1. Weighted pull ups (3 sets to failure)
2. Dumbbell rows (3 sets of 10-12 reps)
3. Hammer strength rowing machine (3 sets 8-10 reps)
4. Inverted rows (2 sets to failure)

That's that easy stuff and I'm feeling it all in my lats as I'm writing this :)
