It's in the core!
Core strength is the core (!) of the game for a triathlete (or any endurance sport athlete). So... I challenged myself to succed in the 30 Day Plank Challenge. Doing a 60 seconds plank is not hard. What is hard it the mental part which consistently doing it EVERY DAY. And that is where a triathlete will or will not succeed : con-sis-ten-cy! You cannot compensate a lack of training by squeezing a 120 minutes run when you missed an entire week of training. The body doesn't work that way. See all the posts out there about injury...Swim Workout
I took the opportunity of a day working from home to spend my lunch hour at the local pool. Not too many swimmers which I like. Just smooth swimming and some drilling.
Another swim workout tomorrow night but with the tri club this time.
