Sonnie Trotter has a nice blog and has often written about topics which I find to be important. If not important they are at least engaging and humorous.
Recently he wrote about The Core, as in that infamous belt which all humans have to protect their spine but which is seriously overlooked in our workouts. I highly recommend jumping on the bandwagon, reading the post and following the discussion.
