[QUOTE 3148156, member: 30090"]Thanks to those who read the OP and gave thier opinion.
The reason I asked was because I read an article that stated standing up out of the seat was counter productive if you are only pushing down because of the weight of the dormant leg. Hence why I asked if you pull and push, or just push.[/QUOTE]
From messing around on a Wattbike I find that my most efficient pedalling requires not so much a "pull" on the upstroke, but more work to pull back at the bottom of the stroke around 6 o'clock. At .least that's what it feels like.
The only time I stand up is either ...
For a very steep, very short hill that I can't ride otherwise - in which case I'll be trying to get as much power out of my legs as possible, so I actively do my "efficient pedalling" motion as opposed to just stamping down. I find this works the core and shoulders to try to stabilise my trunk to give my legs something to work against (not sure if that makes sense, but that's what it feels like). I can't keep that up for long.
For a long draggy hill and need to just change position in order to suffer in a different way. In which case I don't actively work both legs, I just mash down and use my considerable weight to propel myself forward.
But really I'm just a lump, not an althete, so it doesn't really matter what I do.
