Hi Marcia,
I tried the BFL plan last year and I enjoyed it. I am slim and was interested in gaining muscle mass and I did notice improvements. I think I noticed changes first in my legs by the third week. I did have to go out and buy a set of 25 lb. dumbbells to do my lat rows and was surprised by my strength gains. The exercise plan can become boring but I had a list of exercises for each body part so that when the boredom set in all I had to do was switch some of the exercises. This worked for me. Aslo I own a barbell with several sets of plates, so working out at home was no problem for me. I prefer it.
As far as the nutrition plan is concerned, I looked over his food list and found other foods to substitute. The first few weeks I only used the items on the list and then later made a few substitutions for variety. I basically planned my meals on Saturday, my cheat day, for the following week. On Sunday afternoons I would baked a full packaged of skinless chicken breast or fish and each day pack my lunch. I also bought several packages of either stir fry veggies or the "california" mix to go with my protein for that days' lunch. For my 10:30 am and 3:30 pm snacks I would have an EAS bar. Most days, because I wasn't that hungry, I would split that bar in half - eat on half in the am and the other in the pm. I had good results and I was never hungry. At first, because I love to eat, I thought the portion sizes would not hold me over from meal to meal or meal to snack but that wasn't the case at all. Some people may find the meal plan boring but I liked not having to do much "thinking" about what to pack eat day. At least for that week I knew what I would have - just pack and go. Chicken at lunch, fish or a meal replacement shake for dinner - this would depend on what time I finished my workout and which workout it happened to be. Obviously the cardio sessions went quicker than the weight training.
Also, I steered clear of the pasta and potatoes! These are my two biggest weaknesses.
I can eat pasta for breakfast, lunch and dinner and have done it too! So this may be why I saw results so fast. I had pasta, potaotes and or rice on my cheat day only. This made the first few weeks easier to bear because I knew that come Saturday it was on - I could have my favorites all day long if I wanted too. I found that as I got further in to the plan my cheat days were becoming a little cleaner, my pasta cravings practically ceased and my migraines were diminishing. This was one other reasn for starting the BFL plan. I had been reading about migraines and triggers and my doctor wanted me to keep a food diary, so I figured I'd kill two birds with one stone.
With this method, I found it easy to monitor my progress, because you're doing the same workout for the full 12 weeks or in my case 3-4 weeks. It definitely helps to switch out one or two exercises here and there. At first keeping the journal was a pain and time-consuming but if you print out the chart from the website and fill in the exercises and the poundage while sitting around watching television (usually on my rest day), then when you're doing the workout itself all you have to do is record any changes when you're doing the workout (like an increase in weights for your lat rows, instead of your 3 sets at 10, 12 and 15 lbs, you used 12, 15 and 20). Figure out a system and things will run more smoothly. On cardio days I only filled in the amount of time and the number of steps on my stairstepper. I don't have a stairstepper that increases in intensity with the touch of a button, you have to switch the levels on the pedals. But I would do 5 minutes at a steady pace and then one minute at a faster pace - just alternating back and forth between the two. Then some sessions would be one long moderate paced extended workout, meaning I would step beyond the recommended 20 minutes.
I found keeping the food journal the most troublesome. So after the first 2 weeks I quit. I guess I should have just carried the journal pages with me to work but since I was pretty much eating the same thing for a full week at a time, I found it unnecessary or maybe just my excuse for not doing it!
I recommend at least giving it a try. Even 4-6 weeks to break past your plateau would be helpful. Plan to start a few days or so after you finish the book. Give yourself time to print out the journal pages, plan your weekly menu and purchase any products you choose to use, if any. I bought bars for the snack times and the EAS ready to drink shakes (at Wal-Mart) for the late evening post-workout meals. I have a hard time getting to sleep if I eat a regular meal late like that, so the drinks were perfect. I think I also had a protein mix but it wasn't the EAS brand. I had a protein shake shortly after rising every morning because I could feel hunger coming on. Then 45 minutes to an hour later I would have my regular breakfast.
I know this is long and I hope I've helped. If you're curious about anything else just ask!
