Folks, thanks for all the advice. I thought I'd give you an update.
I've been at it for 4 weeks. Today I just started my 5s. the 10s went great and I hit my maxes just about spot on. So far so good. I have not been sore yet, which still bugs me a bit. But I'm getting results.
The diet seems to be working. I've gained about 4 pounds. My secret is something called 'food', which had been suggested by some of the more insightful contributors to this thread. It seems that if I eat more of it, I gain weight. Whoda thunk.
Before each workout I do 2 scoops of When in 10 oz of Soy milk and a bit of walnut oil (maybe 50 grams of protein). During my workout I drink about 16 oz of Cytomax (33 grams carbs). Immediately after, I drink a 17 oz pre-packaged protein thing -- another 42 gr of protein at 17 carbs. I workout in the morning, so by the time I finish, I've had about 1000 cals. On the days I workout, I'll eat some simple carbs and starches (white bread and pasta mostly) whcih is a change for me. I usually avoid simple carbs like the plague. I generally shoot for 3500 cals/day.
On the days that I don't work out, I still do 200 gr + of Protein, but all of my carbs are complex carbs. I generally shoot for 2500 to 300 cals on my days off.
I seem to be gaining weight without gaining fat. This is a good thing.
Now concerning the 5s, I'm a bit concerned that I might have overshot. I picked up on the 5s at the weight ranges that I left off at on the 10s. Except for dips, where I started the 5s a bit heavier than where I finished the 10s. For example, my 10RM max on Squats was 145 lbs. I started the 5s at 145 lbs. I interleave squats with deads, so across the 6 workouts I do squats three times and deads three times. I want to progress squats from 145 to 160 to 175. But now I'm not sure that I can make it to 175. Is it better to reduce the intervals (go from 145 to 155 to 165) and risk undershooting my max or should I stick to the progression at the risk that I will only be able to do 3 reps at 175?
