Weight training exercises, barbell curls pointless for a trackie?

Well make your own constructive contributions and add a link? I've searched loads on this forum, which seems to only be dominated by for sale threads when searching 'track sprinting'.

It may well be why there is a distinct lack of regular posting on here.

I've already written loads in those discussions. I'm not going to do your searching for you too. Why not start with the most likely forums (track, general, rides and races), then experiment with in-post search terms like strength, conditioning, endurance, VO2Max, twitch fibres, cadence, souplesse, core, blah blah blah.

Stop fucking whingeing. And have a look at fixedgearfever.com too. Or ask a librarian to do a literature search for you in the relevant journals.
