Well you have probably seen at the gym a lot of these cardio machines will tell you your heart rate. What to make of it all?
I thought I had a general idea, but there are some interesting things I didn't know.
After hitting 186 today (I'm 32) that scared the crap out of me. As that is a bit high. Well I shouldnt be too worried, just don't continue going so hard. However, the excercise becomes ineffective at this point because your muscles are not getting the oxygen they need.
Here is an outstanding read about it, as well as a calculator.
