I don't know if this helps - but do your rides start off with a nice flat section or do you start climbing hills immediately? If I ride out of my house, I've got about a 4 mile flat section before I have any hills, and I find that really helps to get me warmed up and my muscles loosened.

If I ride out of my bf's house, it's 2-3 miles of hill climbs immediately, and it kills me even though it's really not that hard a hill. My knees & muscles just don't like immediately starting to climb.

I was thinking about you yesterday - Sunday I biked out from the bf's and my right knee was tight & achy the entire time, I just couldn't get it loosened up. I rode out from my house yesterday, the knee started out tight, but it eventually loosened up after the warm up and felt fine the rest of the ride.

I need to try getting on the trainer and actually warming up before riding out from his house and seeing if it makes it start off easier.

I told him he needed to move or I needed a new bf
