Headed to the gym at 6AM hoping to hit the core hard today.  My kid bought me a Strength Training for Triathletes book for Christmas and it had a bunch of new exercises to build the core and strengthen some other areas.  Today ended up being a long list and a lot of reps (See entire workout below.  Total weight seems quite inflated.  I will have to learn more about this app and make adjustments.), but I think if I do this one big core workout and two smaller ones each week it will be a big help for the endurance and avoiding injury.

I also swam 40 laps in the gym pool sans wetsuit.  It is definitely a little harder workout without my bouyant neoprene second skin.

Here is a short video (quite boring actually) of one of my favorite core exercises.  The Plank is quite popular for people building their core.  However, I put a little twist on it that I learned somewhere along the way and made it into a Walking Plank.  Basically, you get into a plank position, take a step to the right and then walk over to a step to the left while holding the plank position.  Currently, I am doing 15 reps per set for a total of 3 sets and 45 reps.
