My bike has been on the trainer all winter, and today was the first day I've ridden outside since november.

Today I felt like I was pushing a lot of weight onto my hands. Felt better in the drops, but really felt cramped when I was on the hoods. I was fine on the trainer all winter, and I was fine last fall.

Is this a flexibility issue? I've been training consistently over the winter, why would I feel so much more uncomfortable when I went outdoors?
