Rating:  Summary: INCREDIBLE MUSCLE MASS GAINS! Review: Power Factor Training is the BEST muscle-building system in the world! I am now ten weeks into the program and I have gained 30 pounds of rock-hard muscle! That's right, THIRTY POUNDS! I've not changed my diet, I've not taken (unlike people on these other bodybuilding "systems") growth drugs, I've simply started training with the principles advocated in this book. Incredible! If you are looking to build bigger muscles in record time, you MUST use Power Factor Training!
Rating:  Summary: Don't expect the results this book promises Review: I read this book about a year ago based on a friend's recommendation. We had both been lifting weights for many years and were at a point in our routines where we felt "maxed out" relative to the weights we were lifting. I changed over to the partial rep routine and did it exclusively for about 6 months. During this 6 month period, I felt good about my workouts since I was progressing according to their system. This good feeling abruptly ended when I decided to go back to a full-movement workout that the authors claimed would not suffer. Not only did I not experience any gains in my full motion workout, but there was actually a drop-off in the amount of weight I was able to lift in several different areas. I thought maybe I was somehow to blame for this deficiency in my workout until I found out my friend experienced the same problem. Needless to say, we are not using this system any more. If you insist on testing this method out, I would suggest you do it for only a month or two so you won't be too far behind where you left off.
Rating:  Summary: put your physics book away! Review: Yes, the "science" is flawed (it doesn't matter, it still *works* by giving you useful feedback). Yes, it's strange at first (so is riding a bicycle the first time, but I'm sure you got over that hurdle). Yes, you may get different results than the next man (but YOUR results will be better than if you had trained the traditional way). I'm sure most of those that dispute the *science* are pencil necks, not real weight-training athletes. I trained power-factor-style in high school after years(3) of show-off training. The result, I got bigger and stronger faster than I ever did before. Bottom line, it works!
Rating:  Summary: Quesionable mathematics but EXCELLENT RESULTS Review: The Power Factor Training book decribes the most revolutionary and effective application of growing muscle on the human body.Sisco is one of the few who are bold enough to describe what really goes on in the sport of professional bodybuilding. Anyone who is interested in naturally gaining muscle should pay the under-priced few dollars for this book. Don't go crazy with the "natural" steroids or protein milkshakes. With the knowledge I gained from reading this book, I have increased my strength and size to such a degree, that strangers fear me, and my family and friends respects me. All this because of my massive muscularity. And the best part is I am spending very little time in the gym. I must admit that that I don't use the math described in the book since mechanical power is difficult to quantify effectively. And I recommend using Smith machines primarily for the Power Factor excercises. Also you will have to make a few excersies up yourself because the book lists very few excersises. But if you read the whole book you will get the most important message: You can never look like Dorian Yates without a radically different approach to weight training. Fortunatly Peter Sisco and John Little provide one.
Rating:  Summary: The TRUE Guide to Maximum Muscle Growth. Review: I have been lifting for about seven years and have been taught by the experts. A Gold Metal Powerlifter, a pro body builder, and Football Strength Coaches in highschool and college levels. I have read several books on weight lifting, this book by far is the best. After using PF for 3 months my bench press went from 310lbs. to about 405lbs. It was unbelievable! Strong-range lifting, why didn't anyone tell me about this. The pf and pi are excellent ways for measuring muscle output. Now I know that I am making progress, and I have the numbers to prove it. Someone stated in another review that the book doesn't mention nutrition, it has a whole chapter on nutrition (ch. 11). This book must be read completely before attemping to do any of the exercises mentioned. I honestly say that Power Factor Training is the most effective form of training to achieve Maximum Muscle Growth that I have ever used. I have been using PF for 6 months now and it still is the most effective workout for muscle stimulation that I have ever used. The weights that I use are so monstrous that I have to train once a week in order to make any progress. The more time I take off from lifting the stronger I get. I suggest (as the book does) to first have a base level of strength before attemping to use Power Factor. So forget the whole "Full deep reps to work the whole muscle" stuff, and go get Power Factor Training ASAP! These guys know their stuff.
Rating:  Summary: This system works!!! Review: If you want to gain lean muscle mass and strenght this is the best way to do it.High intensity training is the best way to train.
Rating:  Summary: The number 2 bodybuilding book in the world!!! Review: This book is very very good almost exceptional. High intensity training is the best way to train, traditional volume training simply doesn't work except you eat all the farmacist's drugs and groth hormones.POWER FACTOR TRAINING overloads the muscle with the most important thing, huge weight.Mike Mentzer's theory isn't fully correct because he backs up full range of motion.I have seen in myself that range of motion doesn't mean anything,my muscles have grown like never before, and i am defenitly much stronger.The musclefibers contract and respond only on huge stress,high weights.This book lags behind only to Peter Sisco's and John Little's new book STATIC CONTRACTION TRAINING.For me these 2 bodybuilding experts have changed the way of training for ever.
Rating:  Summary: Some valid points, but contains serious errors. Review: I have written an extensive review of the book... the following is a brief excerpt: "In their book Power Factor Training, Peter Sisco and John Little make the mistake of attempting to measure muscular force output, or metabolic work, using a formula based on measurements of mechanical work and power. This Power Factor is determined by multiplying the amount of weight used during an exercise by how many repetitions are performed, and dividing the result by the duration of the exercise in minutes. For example, if you were to perform 10 repetitions of the bench press with 300 pounds in 2 minutes, your Power Factor would be 1,500 pounds per minute. Sisco and Little claim this allows for a "precise numerical measurement of muscular output," and that it "...represents a revolution in strength training." (p. 16) The truth is, the Power Factor measurement represents nothing more than a tangled mess of assumptions based on misunderstandings of various basic principles of mechanical physics and exercise. As Arthur Jones discovered decades ago while developing testing machines for Nautilus research, mechanical definitions of work and power do not apply to metabolic work. As he explains in the above quote from The Metabolic Cost of Negative Work, any attempts to accurately measure exercise intensity or muscular force output based on measurements of mechanical work and power are futile. This alone is reason enough to completely disregard the Power Factor as a "...precise numerical measurement of muscular output" without further discussion. However, there are numerous other flaws in the Power Factor Training theory that I feel deserve mention, as they illustrate several important points..." While high intensity strength training (HIT) is an effective and efficient protocol, the PFT variant of it is seriously flawed.
Rating:  Summary: Measusurements of Intensity in Strength Training Review: This is THE best book on the concepts of progressive resistance strength training that I know of. If you truly want to understand the nature of progressive intensity in strength training, this is the only book you need. It is truly the ultimate book on measuring intensity in exercise.
