Hi Robert,
I realise these are probably aimed at the authors, but I’ll hazard a guess…
Your first question has been asked previously, if I remember correctly the answer was they are the same and it was a typo.
Re: climbing – the answer seems to be – count it, but 4 hours at the wall is unlikely to be equal to 4 hours running. I think as long as your consistent in logging it doesn’t matter. Personally I tend to log about 1/3 of the time at the wall/gym. I keep meaning to calculate actual time moving but haven’t yet done it.
I’ve always seen it recommended to do max strength before muscular endurance. Or strength before aerobic. Interested to hear the “official” answer on this.
I had good results doing bouldering sessions followed by a few sets of squats or box step ups and maybe some weighted pullups if there was anything left in the arms.
