What's your post-practice stretching/mobility routine that I can steal? How often are you doing core workouts? (I'll take that to steal too) Thank you!

Hello! I was curious about Galen rupp's higschool career and tried finding oregon state champs or big meet footages of maybe him running there, but unfortunately I couldn't find any. Only ones that exist are Footlocker nationals and pretty much it. I also looked on various websites for oregon state, youtube, runnerspace,​ Dyestat, etc. I couldn't find anything. Is there anyone who has footage of him or have clues where to find it? Thanks!​
