GVT is easy to comprehend, but hard to do. A word of warning....you will be sore. This is no-holds barred training; pain will be intense. GVT is extremely effective, but not for the light-hearted. First, pick an exercise for three body parts. Perform 10 sets of 10 reps at 70 to 75 percent of your one-rep max for each exercise. Use a stopwatch and allow yourself only one minute?s rest between sets.
German volume training, also known as the "ten sets method," is a very effective way to put on muscle fast. The ten sets method was used in Germany in the off-season to help weightlifters gain lean body mass.
GVT involves, rather simply, doing ten sets of the same exercise, with the goal being to do ten reps per set. The traditional method to decide your initial weight is to select an amount of resistance that you can do 20 times, and for most people, this equates to a weight that's approximately 60% of your 1RM (the maximum amount of weight you can lift one time on any given exercise).
Again, for most this is still too much. I don't run my programs like this year round, but I do swim 30 laps every morning.
