it's from Jim Wendler- it's the second week (of four), you always finish the heaviest set w/ a +- so as many as you can do; week 1 is 5/5/5+, week 2 3/3/3+, week 3 is 5/3/1+, week four is a lighter, recovery week
the 10 reps at 70% of one rep max I add to weeks 2&3 just to give them a little more volume
it's (Wendler) the best strength program I've stumbled on thus far!
Ah yes 531 it is a good basic strength program. Never seen it written out like that. It lacks hitting your one rep max but you can adjust for that. I think there are better but it is a solid beginner program.
