Today was a 30-min lower body with a 15-min elliptical warmup.
I saw a sports medicine group yesterday, to get an actual professional opinion on my weaknesses. They took an x-ray just because of my scoliosis, but nothing structurally or nerve-related is causing my issues, in their opinion, just weakness and imbalance. They prescribed me PT but it sounds like the real prescription is... **core strength**

I know Im a whiner but I really don't know how I'm going to motivate myself to do it. It's a real Matthew effect: Core work is very unpleasant, because I"m so weak, but I just get weaker because I don't work on it.
I made an appointment with a PT that a) is close to my apartment and b) at least mentions sports rehab and running specifically on their website. I'll at least go get evaluated and go a few times to see what they give me to do. The main goal for me is to get some exercises I can do on my own.
How do you motivate yourself to do something that is not directly related to the thing you enjoy doing, and that doesn't have a specific goal? It's not like I'm going to enter an abs competition like I'd enter a race, to give me a goal and benchmarks etc. Plus obviously I love running but hate this stuff.
