Bride/bit is the same for over year, saddle/pads are the same since Aug, we evaluated the back (by pinching and pulling all over), but she doesn't seem to care about the back. Nothing seems to change besides the weather. My trainer also guessed other week that if they don't move enough, the back may stay stiff on daily basis (and yes, I havn't seen them running and playing as much when the cold hit).
So what would be good exercises to warm up her back? Lunging any special way?
I tried to give a massage before the ride, but it didn't seem to change anything much.
