V02 Session - Going into some V02 work. Short intervals with short recovery to keep the work in the area. As a percentage of FTP, your individual V02 max is quite variable. You want to push to a feeling of breathing hard but not at a max effort. You might head towards a max effort towards the end of the intervals. We don;t want to do loads of this just yet as it is early in the winter but we always want to touch some of this work throughout.
