It seems silly to say I don't know how to breathe, but I don't. When doing weights, I know you exhale when you do the work part of the rep. In Yoga similarly breathe out on the stretch. Rock climbing too, when you pull yourself up breathe out. The list goes on. What on earth do I do for cycling.
Is it different for riding on flats or going up hill?
I am talking here about when a reasonable amount of effort is being put in, not necessarily racing or time trial but not exactly bumbling along either. I remember when I was younger and did Cross country running at school we were taught to do two short breaths in and two out. Does that apply here or is there something else. I saw watching time trials no TV that some of the riders seem to ride with their mouth wide open. I tried this and found that on hot dry days it really hurt my throat and lungs.
