I have been able to get stronger working with weights, but not considerably bigger. I have actually seen more size increase by working high rep pushups, pullups, and bag work- heavy weights just never got me big no matter how much I ate.


Two ways to increase size- muscle fiber hypertrophy (strength- low rep high weight) and increased vascularity (blood flow- low weight high rep). I gain faster with vascularity, and increased blood flow can be used to increase strength and hypertrophy gains. It is a two way street, but everybody is different.
