Best wrist stop watch for a trainer to have? ADVERTISEMENT 1.17K viewsFebruary 3, 2013 0 Kristin February 3, 2013 0 Comments I am a trainer who also teaches lots of interval classes, too. I was wondering if any of my fellow trainers found a wrist watch that was easy to do timers and stop watch…Thanks! 11 Answers ActiveVotedNewestOldest 0 Harris12 Posted 0 Comments I use MIO, it’s inexpensive and gets the job done…but so does any other stop watch :-).
