As far as rep schemes go, the one's that have been most beneficial for increasing squats or deadlifts is alternating the 5/4/3/2/1 system with 5x5.The 5/4/3/2/1 system is brutal but works quite well for me.If you're not familiar with it, it goes like this:After warming up with several progressively heavier sets, pick a weight were you can just barely complete 5 reps in good form.Add a small amount of weight and after resting about 3 minutes or so, try to get four reps.Keep repeating until you have worked up to a one rep max.This is very demanding, which is why I like to do the 5x5 the following week before going back to 5/4/3/2/1.If you aren't accustomed to doing low rep work, I would skip this idea.
