TBH I thought the leg presses were a joke, your tibia and femur should get to a 90 degree angle. Those squats with that bar much easier, especially when you are holding onto the rack like he was. I have a feeling Branch trained much different when he was establishing those huge legs.
At this point in his career knowing full well he is bottom heavy I'm sure he is not putting the kind of effort into his leg training as he once did. He has said it his self he needs to bring up his upper body to match his legs. So I'm sure his training now for his legs is basically maintenance.
