There’s seem to be a lot of trainers who believe that a body part can only grow so much before training the rest of the body. As in your arms will only grow so much if you only train your arms, they’ll grow quicker if you train your whole body. Then I. The other hand you have trainers like Christian Thibadeau that use the analogy of “training money”, as in you only have so much so spend it on what you need to grow. To keep with the example, do you guys believe that training only arms will make arms grow just as much as if you train the whole body?
