I ended up buying this book for my Kindle because - I didn't have a good phrase for it until now - I'm "skinny fat", as Rachel says. She hit the head on the nail when she said I am slender, don't want to drop any pounds on the scale necessarily, and look good in my clothes, but my arms are mush with a bone in the middle! I run half marathons a couple times a year, do P90X once or twice a week (OK or month), and occasionally do some planks for my abs, but have never achieved the body I want and hate wearing a bathing suit. I am 24 so I figure if I can't get it now I'll never get it, so I purchased her book but didn't have too high of hopes since I thought I knew what I was doing.Boy was I wrong! It was my first fitness book purchase and everything I was previously worried about in following a fitness program like this isn't an issue here. For example, I don't want to start a program that lasts a few months and then leaves you with no long-term plan, and I don't want to count every single calorie, and I better be able to drink on the weekends and eat cake on my friends' birthdays. I also don't want to have to think too much about what workout to do on what day, like "Did I lift my biceps last time, or my chest?". And I am a grad student planning a wedding so I also want to use my time efficiently.Her book gave me all this and more! Granted I'm only a couple weeks into it, but if I don't succeed it won't be because she didn't give me all the tools I needed, it will be because I got lazy or something. The rules for eating are very straightforward - I don't need to pull out her book when I'm at a restaurant because I forgot rule 47 or anything - they make sense and don't require any memorization, just common sense. The workout plans are very detailed and strengthen your body in important, natural ways rather than machines at the gym that focus on one muscle that you probably don't use much anyways, and she takes the guesswork out of which body part to train and when.Overall I recommend this book even for those of you who think you know what you're doing but can't figure out why it doesn't show in the mirror! Not only are all the workout plans very detailed, but she gives great analogies and lessons that alone can motivate you to kick your own butt in the gym. The two most important things I've learned so far are that 1) endurance running trains your body to efficiently run for long periods of time... so I've basically trained my body to not get any more fit! Oops. And 2) even if I see skinny girls in sports bras on the treadmill, they probably already had that body type and all that running to nowhere isn't going to get me the body that I want if I don't have it by now!I hope I can stick to her program because I've wasted hours a week (up to 20!) with excess cardio for half marathon training and never gotten the results I wanted. The only thing I don't care for much is all the BITCH talk, because when I'm in my clothes I'm the BITCH everyone talks about ;) and now when I'm in my swimsuit I will be too!
