I usually hang around 140 during the jog and might peak up to 180 during the sprints.. Hard to say, I don't have a fitbit anymore.
My understanding has always been that once you cant speak clearly, than rest until you can.. Rinse and repeat.
Sounds about right to me.
I've been messing around with some longer, progression intervals- really makes the shorter ones easier
I'm not sure if you or anyone else finds this, or if its just me, but I find intervals so tough mentally, like once you finish that all out part and then you have to do it again
