The Patient Lifter 6 x [2-4] Method - with this training system, we start off with a weight that we can handle comfortably for six sets of just two repetitions.  Depending on your neurological efficiency, that will translate into about 80 to 87% of your 1RM.  The goal is to increase your strength SLOWLY over time so that you can handle that same wight for six sets of 4 repetitions.  

The reason The Patient Lifter's Method works is that the load increases only when the trainee can complete all sets of 4 repetitions with the starting weight of 6 sets of 2 repetitions.  The system works using what is called the law of repeated efforts because the nervous system is forced to accept the loads as being normal.
