How to train your lats.
The lats appear to be a pretty even fiber type split, with around 50% fast and 50% slow twitch fibers. This means a wide range of repetitions and rest periods should be used and you should also (occasionally) utilize aids like lifting straps to ensure that your grip is not failing before your lats – whether it be due to super heavy weights or high reps and fatigue.
