I increased it as I felt necessary. With the previous exercises growing in weight, you'll be more exhausted come time for the 2x8-10 exercises each week, so upping all of them could end up being a problem, unless you do so fractionally.
go with an easy weigh at first something you can do 10-12 reps with. Because it will take your body time to adjust to so many loads at 5 reps. Every week add 2.5-10 lbs depending on the type of movement. Large body part try 5-10 small body part 2.5-5. You want your body to build momentum the further you get into this routine. the problem s that to many poepl test themselves each workout. the end up hiting a wall and not getting past that.
