Good point actually - when I do speed work I'm up on my toes & likewise when I want to force it on a bike I am also the same. Also jumping round dancing like a loon in a nightclub, I'm also on my toes - giving more strength in my calves.

Build a bit of quad strength helps on the ascents as well. Most of it however is mental.

(LOL just realised I could market this as the AllanT fun hillclimbing strength regime!!!)
