TRX is a Monster!!

I thought I would switch it up this afternoon and do a little TRX instead of free weights.  I think I should of stuck to the free weights.  It's been awhile since I've done TRX and I always forget how killer of a work out it is.  You definitely need a strong core to do most of the exercises associated with TRX, which I DON'T have.  But I guess I need to be consistent with it to get that strong core.  Anyways, it was such a good work out it was giving me back cramps in places I didn't think I had muscles.  Good times.  I got in my morning run and then another 35 minutes on the treadmill this afternoon for a total of 7.48 miles for the day.  I should sleep good tonight.  Until next time...
