Well, I have been busy designing and building a logbook function to my iCoach project over on my Coaching/Instruction website. At the moment if you register you can complete a performance profile which will give you 5 climbing attributes to focus your training on over the next month.
To compliment this, I have added a way to log you training be it climbing indoors or out, running or mental skills training. As well as logging each route by grade, I am encouraging people to get used to using the PRE scale (Perceived Rate of Exertion), this if you like adds another performance measure.
Over time you should notice that your PRE for a given grade will decrease, before you Grade increases. Whilst at the moment there is not an outputting page, my idea is to follow this up in about a month with a page that allows you to look at monthly averages against session.
Eventually I might even add a facility that will add overload to your session, printing you out a programme for your next wall session.
