If I'm not mistaken, it's the 6 week version of the 3 lift, 9 week russian peaking cycle... That one is alright (as long as you don't do it for lifts you really aren't built for), but I don't like the condensed one-lift thing personally...
It has 2 workouts, light and heavy, done for 3 sessions per week (i.e. light, heavy, light, then reverse that next week).
On the light ones you just keep doing 80% of your old 1RM for 6 sets of 2.
On the heavy days you start with 80% for 6 sets of 3, work your way up to 6 sets of 6 then go down 1 rep and 1 set each until you hit a single (I think). You'll likely get more weight out of the cycle than what you're doing for that single though... At least that's the way it usually is with the 9 week routine... I tried the 6 week thing several times but finally gave up on it because it always murders my hips.
