I must be doing it all wrong. As soon as I want to put in effort- I slide forward on the saddle and onto the hoods. That position puts me into the position I need for me to climb.

Have to admit that Most others I see are back on the flats and more upright and I have tried that position- but it just does not work for me. Must come from years of Mountain biking where I am trying to keep the weight on the front wheel to stop it lifting.
