We've seen a lot from Cody Montgomery lately. It's not shocker consider just how hard he goes every single day. He really shows us how much effort it takes to be a serious competitor in the realm of professional bodybuilding.

He is joined today by a new friend, Isaac Miranda, who has joined Cody today fora rigorous back routine.

The back can be a tricky muscle group to develop properly, with the risk of strain being so prevalent. Luckily Cody and Isaac make it look easy, paying great attention to the finer details and displaying their mastery of proper lifting techniques.
