I have been doing this particular routine since the beginning of summer, but I'm ignorant of how many cycles it's been. I get bored very easily, and so I like the variation. I am trying to maintain a very lean physique, and I like a lot of definition in my muscles. I think that this routine has really helped me with that aspect of training, though I have a very wimpy upper body as far as size goes(lots of definition, just not mass).
I train my whole body 3x a week. The longest workout, Wk. 1, takes probably about 45 minutes or so, including minute rests between sets. I use one exercise per body part. Wk. 2 and 3 take about 30 minutes each, and I try to rest a little longer. Wk. 4 is a breeze, maybe 20 minutes of work. It happened that Wk. 4 fell around Thanksgiving and Christmas, so I had a break around the holidays! I do 50 minutes of cardio every other day, between the weight workouts. The original routine had you break the cardio down, too, but I found it to be too much of a pain, plus, for me, more cardio is better.
I used to do a "by the book" Body for Life weightlifting routine that included pyramiding my weights and supersets, and I feel that this routine has helped me achieve my goals even better and takes less time. I got my current routine out of a women's fitness magazine
*cough* ~~ how embarassing, eh? I'm not looking to get "huge", anyway, just be lean and mean!
I just got some amateur photos taken, and I've got plans to take more in about a month to see if I can improve! Wish me luck ~~ good luck to you, too!
