I thought, what an arrogant guy, he discussed how decision at the summit to make a phone call to his wife, left him queueing for the decent,

You'll learn quickly just by doing it, and watching others on the wall. As well as your muscle strength, your tendons and ligaments will toughen up, which takes a lot longer than muscles. 
Luckily it's winter season and pulling on axes doesn't hurt so I should be back to full strength by the summer, just need winter to hit properly in Snowdonia and the Lakes as driving to Scotland is a pain!
