http://www.sosuave.net/forum/showthread.php?t=98203 The thing I see missing is chest & arm work (most guys do too much of both, of course). One thought would be to replace shoulders & lats with bench (probably incline) and dips on one of the days.
try cutting down your worksets to just 2 or 3, but make sure you warm up properly (this will probably require more or less than a total of 6 sets including both warm ups and worksets for some exercises).
Let's say you start out with a bench press of 135 (ok, it's not on your list, but work with me).
Others may offer tweaks, but I'd recommend to start with an empty bar with 8-12 reps, then add weight at 20-30 lbs. per warmup set, and generally reduce the reps in half, until you get to your worksets. Soooooo, you get
warm ups
45 (empty bar) x 8
75 x 4
105 x 2
worksets
135 x 6 x 3 (you can generally afford to cut this down to 5 x 2).
So you may still get 6 sets, but you're warming up with a pyramid, to get blood flowing while still leaving lots of glycogen for your worksets.
Deadlifting 200?
45 (bar) x 12
75 x 6
105 x 3
135 x 2
165 x 1
185 x 1
200 x 5 x 2
Since you're only working out twice a week, I suggest that with the last set you go balls out, lifting as much as you can as many times as you can. if that's over your day's goal x 5 x 2, then the hell with your goal, blast right through it. But be prepared to eat afterwards & walk a little funny
