I haven't weighed myself in a week or more, but last time I weighed 232lbs and I probably weigh more now. I'll prolly weigh 240lbs by the time I finish this second cycle.
I finished up the last one, took a week off from lifting and then started over again. This is the end of week 2.
I'll take a week off after this cycle, and then I'm gonna try something out. I'm gonna run the exact same exercise setup except I'll switch barbell press to dumbell press and barbell rows to dumbell rows for a change. Also, it won't be a dual factor style program, but more like the regular Bill Starr style 5x5, but I'll be doing 8,6,4,3,2,1 and pyramiding so the single on all exercises 3x a week hits with monday being heavy day(90% of 1rm), wednesday light day(70% of 1rm) and friday being medium day(80% of 1rm).
I'll run it for 4-6 weeks with the goal of putting 10 or more pounds on all my sets of all exercises.
Then I think I will run the Bill Starr 5x5 with the heavy/light/medium setup for a phase of high volume for 4-6 weeks.
Then I'll go back and do another run or 2 of Madcow2's Dual-factor 5x5.
I'll weigh 250 by then easy.
As for you gaining bodyweight, you WILL!
But, this is the key. MAKE SURE YOU EAT ALOT! And I don't mean alot by your standards, but by anyone's standards practically. At your bodyweight I'd aim for 4000 calories a day with most of that being carbs, then protein then fats. Like 200 gram protein, 100 grams fat and 550-600 grams carbs. You will gain. It will be scientifically impossible not to gain. And try to get around at least 6 hours sleep a night minimum and 7 or more would be better. Then sleep 9-10 hours each day of the weekend to recover your minor sleep deficit from the week.
You can do it rob. EAT ALOT!!! SLeep as best you can. Train hard in the gym, but don't psyche yourself up.
And if you're seriously about gaining, I'd drop tumbling bro. Seriously. I know it's fun and spinning and flipping is fun, but it won't help your muscle gain. It might help a tad, but then again you'd better be EATING ALOT for it to actually help overall progress.
Godd luck bro.
