First, was your previous workout effective? Were you feeling and seeing results? If no.. give the magazine workout a try. You'll have to customize it to suit you, obviously. Don't use the weights they recommend, use the ones that work for your body.

I looked at your gym log and it seemed like it was the same thing, every day: a circuit, and cardio. If that wasn't giving you good results try breaking up your circuit into two or three diff workouts, and work the crap out of the muscle group you're concentrating on. Then work the muscle group every four days, with the exception of legs because if you work them hard enough you can do them ever 6-7 days, adding cardio throughout the week.

eg: Monday - legs and butt
tue: back and shoulders
we: arms and chest

sat: back and shoulders
sun: arms and chest
mon: legs and butt

and so on, just get enough rest days inbetween working your muscles.

Or break it up into two workouts: 1) legs&butt 2) chest and back and arms.
