Core Routine for Runners: The Dozen


I've historically been a low-intensity cross-trainer, but as I get older the ratio of rehab and "prehab" time to running time just gets bigger. I'm about 1:1 now...but it is still totally worth it to be able to run and train with my friends and Oisellistas! I had a pretty low intensity core set up until this winter: planks/side planks, touch-overs, and pushups (a lot of pushups before #totallytrials!). Then I was introduced to the "Dirty Dozen" this winter by my favorite Oregon HS coach and Oiselle fan. I quote: 

"Of course you realize that I didn't invent any of these exercises...only orchestrated the collection to be a balanced set of front/back/side core exercises with just enough arm work to encourage my high school runners to be both tougher and less injury prone. If you get busy they should take you about 15 minutes post run...a small investment of time that can pay big dividends to any runner."

The first time I tried the Dozen, I couldn't do 4 of them at all (side to side abs scissor, side plank leg raises, v-ups, and standing glute iso's)! Now, I can whip through the whole set (giving about 20-30 sec rest between exercises) in about 20 minutes. If I'm feeling super strong, I increase the time in the positions or suggested #'s of reps. Instead of the forward standing glute iso's I do a standing one leg balance like below, except with both hands on my front foot, keeping my face forward and shoulders flat. It's a great hammy/butt stretch, holding for 30 seconds. 


Before I started doing The Dozen, I had a little nagging left hip soreness...which has since totally disappeared. I have also noticed my sitting posture has improved. I try to do this routine at least 3x/week, with another 2 days of an abbreviated set: side plank leg raise, back bridges, and v-ups. I also throw in one-legged stair heel dips, hip dips, one legged bosu ball balances, and quad strengtheners at least 3x/week. And one day before abs-modeling, a spray tan :) Have questions?
