How to do the divergent lat pulldown back exercise:
Pull down the handles to a comfortable starting position as the handles are fairly high up, with palms facing forwards.
Pull down as far as you comfortably can with your shoulders back. As you pull down, the handles will diverge to a wider extent than with the traditional pulldown.
Release and return to the starting position. I like to go a little higher up to get more of a stretch of the lats.
Breathe out as you pull down and breathe in as you release.
Do about 4-5 sets of 12 repetitions.
