My watch is trying to kill me. I have a love hate relationship with my Pebble. For the most part I love this gizmo because there is always something new you can do with it. Today, after talking about for a while, I finally tried the 7 Minute Workout on my Pebble. Two things are apparent: I am unable to exercise for 7 minutes a day without getting a heart attack, and if I continue exercising for 7 minutes per day I will have a heart attack. Tomorrow I will think long and hard before turning my Pebble on again for exercise purposes, perhaps I will just stick with it to tell time and to measure my walking distances. Much safer that way.
