Yep i always wear my fit bit. I have the charge HR. So as soon as the session starts, i start the timer. I counts as a workout and it lets me keep track of time during the session.
It is definately a workout. some of reports show my heart rate as high as 200 beats per minute. lol
My team's incubator is working on the "Cockbit".. Monitors alot of vitals.Eg. how many ounces of jism are in the sac etc.
Now this device is not worn on the wrist like the Fitbit...Patent pending of course. Will keep you posted. It's kind of a start up. I think we are in our second round of funding. But you really have to see the Power Point to grasp the enormity of the concept and the investment opportunity.
