Chins
Is there a reason for chins, as opposed to pullups? Assuming there isn't a big difference. I couldn't agree more about the lat builder comment. I started doing pullups in about March/April this year. I've had more growth since March with pullups than I've had in 7 years from pulldowns. And I've only been onto weighted pullups for a couple of weeks.
Deadlifting (back on topic)
At any weight is it a good idea to go past 5-6 reps? Your form inevitably begins to slip and the issues with that only grows as the weight increases.
Chin-ups, pull-ups both good. But I beleive supinated or even better, parallel is going to make a bigger impact on the lat's and friends than pronated, which I think that is what a pull-up is called.
But as a back builder, the muscles of the back are going to receive more "mechanical" work with the row and chin than the dead-lift which is more isometric which builds strength, but not as efficiently as exercises that apply mechanical work to the muscles under load.
Fuck, that's too nerdy.
