Is those Piquet turns constantly going in that big circles of starting from one area and going all the way around the stage and finishing on the other side at the end of the peaky turns those air for me, stamina wise, where I get the most frustrated and low on energy, the peak image some of the major points I'm thinking about, Ah, lot of them is upper body, having the upper body held but not pushing down so your ribs can't move when you're doing the peek a turn because the turn comes from the upper body and the ability to move the rib cage around your spinal cord.
