Arnold also talks about eating 5 meals per day and how this allowed this allowed him to pack on the muscle in a hurry due to the amount of protein he was eating while training. During his training Arnold was fond of drinking 2 protein drinks per day, plus meals, plus supplements in order to maintain peak muscle growth efficiency.
For those people seeking to build muscle it is important that you stick with it and KEEP TRAINING and follow a strict diet. Quitting, slacking off on the dietary requirements, slacking off on workouts will cause the body to either plateau or go back to its old condition. You need to keep shocking the body with new challenges regularly in order to maintain muscle growth.
Arnold also routinely tried out other sports and activities in order to give his body new challenges - archery was just one of them.
