Walk

Matija Prajo, a friend from Split and professional kinesiologist told me long time ago ..
"When you are overweight running doesnt help because the heart rate is too high and it is not helping in loosing weight. You should walk. But wisely.
You should walk at least 40 min just a bit faster then ordinary walk and the heart rate has to be 18 - 20 pulses per 10 sec .. in total .. around 115 pulses per 1 minute."

I have experience of walking around 40 min just enough when you feel you are starting sweating.
And having the heart rate of 18-20 pulses per 10 sec. When I would eat properly all day long and not eating after 6 pm .. i would loose around 0.3 kg daily.

So, anytime in the day i will go for a bit faster walk at least 40 minutes long.

What else could I do?
