In weightlifting there is 2 main ideas for training the Bulgarian and Russian systems. In a nut shell the Bulgarian system is training low reps (1-2) with over 90% all the time and the Russian is varying reps and varying percents from workout to workout. The Russian system will follow a percentage cycle building up to compete at the end while the Bulgarian system has lifters always ready to compete. With weightlifting it really doesn't matter which way you go, just stick to one method. Weightlifting training is way different from powerlifting, weightlifter's lift every weight at full speed to build speed and strength. Hope this helps a little.
