2 sets

[Stewilliams]

isn't the goal to get stronger. bigger???

so 2 sets of 315 for 10-12 rps short of failure will actually induce more growth than 1 set of 315 x 10 and 1 of 365 x 8??

I didn't say W won't take any sets to failure, I just would only take the final one to failure as instructed in the book. This would likely enable you to make better strength and size gains versus two sets to failure (it at least has in my experience). Imagine that your 10 rep max on barbell row is 220lbs. First set you take to failure with 220lbs and get 10 reps. Then the second set you get 6 or 7 due to the fatigue accumulated from the first set. Would this be more beneficial than getting 9 on the first set and leaving a rep in the tank, then going to failure and getting 9 reps again on the 2nd set?
