Early morning abdominal work. Truth be told, I train my core everytime before the real session starts. I practice and rehearsed what I think is an invaluable tool for some 20+ years now. Sometimes it may take an hour other times I’m so focused it can be 30 minutes but what’s important is that we stick to it because in the end it comes down to enduring the long distance not just the short sprint. #LetsWork
