Isometrics

In order to gain rock hard muscle definition, you can combine isometrics with your weight training.
Overview:
When exercising your focus body part, generally you want to break down the muscle for a select focus area. Let's use the example of shoulders. Say you are focused on shoulders for about 3 weeks in your workouts. This would mean you are working your shoulders extremely hard ( to failure) about once per week, and very hard another day of the week. The rest of your body is just maintained during this 3 week cycle where you do moderate workouts on your non-focus areas, such as chest, arms, back, and legs. These areas do not go to failure on sets.
Isometrics:
Eg. Shoulders... Your first 3-6 sets of exercises on shoulder day will be to absolutely break down and kill your shoulders. You go until failure on each of your initial 3-6 sets ( i.e. Shoulder presses 3 sets - 12, 10, 10 ), but immediately following each set take a deep breath, extend your arms out to the sides and back. Now squeeze your shoulders tight. Crush them. Make them shiver in a solid contraction. What this does is it helps to force blood deep into your muscle tissues, where it can start to bond with myosin, a protein in your skeletal muscles. This bonding effect is where your muscles will form receptor sites for absorbing and utilizing protein. You know protein, that expesive supplement that everyone tells you to buy.
So in doing this with your shoulders, biceps, back, etc , you will be gaining a major shaping and hardening factor. This idea follows a technique called negatives in which once you have failed a muscle, biceps, chest, back, etc... you then release your last repetition very slowly to help break the muscle down. Isometrics, however, allow you to fully contract that same muscle as much as possible, giving you better circulation and definition, and a distinct advantage of a growth factor.
By using this method, it is possible to pass the progress of others who are 6 months ahead of you in muscular development.
Ladies:
Just a note to ladies reading this. Women can also benefit from isometrics to quickly gain shape in their legs, back, arms, ass, etc... This technique is not for building larger muscle, it is more for developing the shape and definition of the muscles. Muscles burn fat, especially conditioned ones. So, if you are using higher repetitions, as women often do, this will give you a more firm build, not necessarily more bulk.
