What is the method of power training?
power training is usually when you lift a very heavy weight for only a couple of reps such as 3-5 or 4-6, you will gain more power and some size with power training, different from bodybuilding where you lift around 8-10 reps and gain more size with some power gains
To be a bit more specific, 3-5 reps is a scheme used for increasing maximal strength. That is only one part of the equation, the other being speed. The speed of the lift determines the power output. For power you'll want to train the olympic lifts which are the snatch and the clean and jerk. Start out with more reps at a lighter weight until you are proficient with them, then move to lower reps for maximum power.
