When riding a non-technical flat or ascent, should the arms support some of the rider's weight?
I have noticed that even in those situations, I can freely let go of the bars and continue pedaling without shifting my weight - all the time being bent forward. Maybe this is because of my bike's geometry, my technique is wrong or this is just normal.
To answer the questions in the comments, I am not sitting up, nor am I strong. I feel as if 80% of my weight is on the saddle, 18% on the pedals (striving to make consistent circles) and 2% on the handlebars (there is some change in my posture when I let go the bars, but it's like 1cm at most). Flat pedals - haven't ridden clips for a while.
It appears that the stem has been replaced with 50mm shorter one, and the fork with 30mm longer one. With my saddle all the way up, the handlebars are still a little higher.
The question stands, however - is this (a) efficient and (b) healthy position for cycling level roads and climbs?
