When I hammer in the flats for an extended period of time, the muscles that first feel fatigued and a little painful are those in the inner thigh (hip adductors, I think?)
b) owing to non-optimimum bike fit or technique?
c) something that can be improved by strength training or other exercises?
d) related to the mild osteoarthritis I have in my hips? (the osteoarthritis is worse in the right hip, but present in both. I feel the fatigue on both sides.)
Suggestions and insight would be most welcome.
