Very cool, thanks for all the effort.
I've been doing cardio in 50 minute sessions where my heart rate seems to stay somewhere between 160-175 and my max hr measured out to 190. So i seem to be pretty up there. I do that about 4 times a week with some weight lifting mixed in during the week too. But i tend to take off saturday/sunday except for maybe a 30-50 mile bike ride depending on the weather.
It's my diet that needs the biggest help.
but i think i'll try that high intensity thing!
