Every time I take a break from riding (Illness or injury) I hate my bikes for a while. I know I am supposed to support my weight with my legs and hold myself up with my stomach and back ... but simply cannot.
I start small, suffer a little, and gain strength. After some amount of time, the bikes feel really comfortable.
When my butt hurts or hands go numb, I know my legs are tired and I am getting lazy.

This is so true, and it took me a couple of years to figure out myself.
