220-your age X 0.85

ok, im 35, so i should get my heart rate above 117?
did i do that right?

that seems sooo low. its SO easy to blow right past that.
and im sure im not getting the right information just using the read outs on the machine. (the charts usually tell me around 102 for fat burn)
is it close, or should i invest in a heart rate monitor? any recommendation on what brand? (not too expensive)

and ktinspired,
yeah, i have been doing HIIT lately.
definitely a good way to get out some aggression!
