I am sort of on a 2 week cycle. One week I work quads and hams together and the next week I split them. It depends on what week it is. When it's the full leg week, I do pullups (as many sets as it takes to get to 20 reps, adding a rep each week), chins (same thing), T-bar rows, one arm rows, cable rows.
When I split the legs and work hams on their own, I do pullups/chins, sldl and back extentions. I used to do pulldowns all the time, but now focus on the pullups/chins.
