I love it.. and use it when strength training..
Isometric workouts are based upon Exercising against a fixed object.The thinking behind this is that one can exert a maximum force against an immovable object.York Barbell Company, sold thousands of isometric power racks. But not long after its rise to pority, isometrics fell out of favor...in the book Dynamic Strength by Harry Wong; he claims you can build muscle and strength without using weights?

Static Contraction Training - Maximum Overload in Minimal Time!
Static contraction training is a unique a form of strength training that maximizes muscle growth, and strength gains, while dramatically reducing the "amount" and "length" of your exercise routine. Static contraction training, instead of focusing on amount of exercise and frequency, emphasizes intensity of the workout session. This is done by working with weights that are far in excess of what you would use during a traditional strength training workout routine. We will explain more below.
In order to understand the theory behind static contraction training, you must first understand how muscle's work, and what causes muscles to grow. Each muscle in your body contains a variety of fibers. Without going into detail for our purposes, each fiber type becomes involved in physical activity at different levels of stress. In other words, if the physical requirements of a particular activity are very light, only certain muscle fibers of the involved in muscle group may be needed to complete that activity. If the physical demands are more strenuous, the muscle may require the involvement of an additional group of muscle fibers. If the physical demands are very strenuous, the muscle may require involvement of all muscle fibers simultaneously. In other words, the muscle fibers in each muscle are recruited into activity based on the amount of and for required to complete the activity.
Muscles get bigger when the body senses, through messages sent to the brain, that your body is unable to handle the load currently being placed against it. When the body determines that it needs to be stronger to complete a particular activity in the future, it signals the growth of additional muscle. Once additional muscle growth has taken place, the body is able to handle an increased load when the stimulating activity is resumed again.
What static contraction training does is to signal the body through intense activity that additional muscle growth is necessary. And, it does this in a way that is very different from traditional strength training methodology. Most of us have been taught to workout with the weight with which they are capable of performing 8-12 repetitions, and to increase the weight when you can do more than 12 repetitions. You then continue to work with the new weight until you can do more than 12 repetitions with that weight. In this traditional approach to weight training, those first 11 repetitions are for the most part simply a preparation for the final repetition which should be very difficult to complete. That is the one that signals the brain that you need to be stronger the next time. This form of weight training, while it works, takes much more time to generate the same results that can be achieved through static contraction training, and here's why.
Instead of trying to take a muscle group to failure through the use of repetitions, static contraction training teaches us to simply hold the maximum weight we can handle (Isometric exercise), in our strongest range of motion for a particular movement, for a maximum of 5-10 seconds, and not to perform any repetitions with that weight. For example, if you normally bench press 150 pounds, you might actually workout with as much as 300 lbs., but instead of attempting to perform repetitions, you would simply hold that weight at the strongest point in the range of motion for the bench press, which would be approximately two to 3 in. before you are able to lock your elbows. Holding that weight in position for five to 10 seconds is all that is required in order to stimulate the brain that additional muscle growth is necessary.
A static contraction training workout involves only five exercises per workout. Typically, you perform your five exercises in less than what amounts to a minute, not including the time it takes for you to set up the machines, and short breaks between exercises. I know this sounds rather extraordinary, and may be causing many of you to think that it sounds too good to be true. I thought the same thing when I first heard about static contraction training. As a result, or I was for cynical too. But, because the routine had been recommended to me by someone with whom I was very familiar, and for whom I have a great deal of respect, I was willing to investigate further and tried for myself. You can find out more about my own personal experience, and the results that I have accomplished by referring to my personal workout routine located on this web site. To make a long story short, I am a firm believer in static contraction training after partiting in this routine for only 60 days. I have seen dramatic improvement in both my strength, muscle size, any dramatic reduction in the amount of time I spend attempting to get results.
Static contraction training is designed to deliver the maximum possible overload to each targeted muscle or muscle group. This goal is accomplished by using what are known as "strong range partials". Using your strongest range of motion means operating (in most exercises) in the last inches of your reach. This is the range where you can handle the most weight and are least susceptible to injury. While the most important steps in beginning a static contraction training workout routine is to determine your "sweet spot". This is the maximum weight that you are capable of handling in each of the exercises that you will perform in the routine.
It sounds simple enough, but for those of us who have engaged in traditional strength training routines, it can takes in getting used to. The reason is that you will be surprised at how much weight you can actually handle in your strongest range of motion. It will be dramatically higher than what you are used to working out with. For example, as I was trying to find my sweet spot, I started out working with 400 lbs. on the leg press machine. I realized right away the weight was much to light for static contraction training. I raised the weight to 500 lbs. and that was still to light. I raised the weight to 600 lbs. and began to find that I was reaching my sweet spot. I added 85 lbs. more and that was a weight with which I could only perform a 10 seconds hold before failure. That became my sweet spot for the leg press machine.
You will need to find your sweet spot for each of the exercises that will be performed in the routine, and it may take you a workout or two to figure that out. Once you have identified your sweet spot, the next most important consideration is "progressive overload". This simply means making sure that you are making progress in each workout by either being able to handle more weight, or being able to hold the last weight for a longer period of time. If you are working out at the highest intensity possible you should see improvement in either your hold time or your weight or both, each time you workout.
The Basic Workout Routine:
The basic Static Contraction Training workout routine consists of 10 exercises. You perform 5 of the exercises in one session, and the other 5 in a separate session. Here's what it looks like:
Mondays: Workout Routine A
Thursdays: Workout Routine B
1) Lower Back
3) Upper Back
How to perform the exercises
In static contraction training you will merely be holding the weight (Isometric exercise) at approximately 2 to 4 inches before completion of the lifting motion. For most exercises, this is the strongest range of motion for that exercise. You will need the assistance of the spotter to move the weight in that position since it is unlikely that you will be able to lifted by yourself, especially if your working with a weight is appropriate for this exercise routine. Your goal is to hold the weight for a minimum of five seconds and a maximum of 10 seconds. If you can hold the weight for longer than 10 seconds, you should increase the weight on your next workout.
Beginners should workout performing one set for their first six workouts. Intermediate trainers should do one to three cents per exercise, depending on how you respond to multiple sets. What we mean by that is if the weight with which you are working allows you to perform three sets holding a minimum of 10 seconds each, you are probably better off to do three sets but also to raise the weight for your next visit. Advanced trainees should perform three to five set per exercise.
Intensity versus Duration
One thing that is important to remember about strength training is the high intensity training cannot be sustained for long periods of time. In other words, you can either workout at a high intensity, or you can workout for a long duration, but you can't do both. Take the example of a sprinter and a distance runner. The sprinter is engaged in a high intensity activity, because sprinting is very strenous when done correctly. By default, that activity is relatively short lived because no one can Sustain
a sprint for very long. A long distance runner, on the other hand, works at a much lower energy level starting out, and therefore can Sustain
it for a much longer duration.
Static Contraction Training when done correctly, simulates the situation of the sprinter by getting maximum intensity out of the workout, which by definition makes the workouts brief. So, if you are able to Sustain
longer workouts, you are probably not working at the appropriate intensity level.
Frequency of Workouts
Also related to the insensity/duration principle is the principle of workout frequency. As the intensity of your workouts increases, your body will require more time to recover, and that is why the frequency of workouts is dramatically decreased in the Static Contraction Training routine. For the first six or so workouts, you should be working out no more than 2 times per week, and then after that, you should be switching to once per week, assuming you are working out at the proper intensity level. This is a must on this workout as your body must be given adequate time to recover AND grow between workouts.
