Strength training is a skill. Basically, everyone is walking around with a "V8 engine" (their musculature) but only firing on "4 cylinders" - no one is actually using their muscles to their fullest potential.

Your body actually keeps you from using all the strength of your muscles, as a safey mechanism. Your strength generally does not exceed 30% of your tendon structural strength. For instance, when people are electricuted their muscles often contract so hard that they break their bone structures.

If you will just go along with these three rules for extreme strength training, hence, you can turn out to be VERY MUCH stronger by learning how to "fire" more of your muscles and get them to contract harder with more pressure:

First Rule: Concentrate On A Limited Full Body Exercises

Only focus on a few, full body exercises. You want your whole body to be strong, so you must train it all as one unit. Plus, you get optimal hormone stimulation by training your whole body this way. Squats, Deadlifts, Overhead Press, and the Bench Press fit the bill.

Rule #2: Focus on High Resistance

Your lifts should be performed with extreme resistance in order to produce strength. This is made by lifting weights (or performing body weight exercises with critical weight distribution and weak force) and by extremely contracting (tensing) your muscles as you lift.

The goal is to obtain additional muscle fibers by:

1. Pressuring each muscle as hard as possible during the exercise and...

2. During which, maintain intense pressure by lifting the weight as hasty as possible.

Rule No. 3: Give Attention To Multiple Sets of Low Reps

Since strength is a skill you can't perform "sloppily". Practice doesn't make perfect, perfect practice makes perfect. Therefore, you have to learn being strong. Every rep should be made as entirely as possile (in line with the above guidelines). Maintain the reps at a low level so that you can remain mentally focused. In the same way, this will keep you from getting weary and sloppy.

Therefore, lift heavy things as possible. While keeping fresh as possible.
