Thread: heart rate (fatburn/cardio)

hello all!
ive been going to the the gym for the past 4 months and along with CC have lost 2stone. i have recently bought a heart rate monitor (the Polar watch one) and im a bit concerned that when i finish at the gym or zumba etc. it shows my max and min heart rate during the session and my max yesterday at zumba went to 192 and today i did boxing at the gym it went up to 180+. this is not within my "zone" ive read a bit about fat burn vs cardio but as im doing like 25 mins tread, 10 mins rowing, 10 mins elliptical and 10 bike with strength and core inbetween should i be keeping in the zone as its only for those small amounts of time? im doing HIIT on all also. i still have 4 st to lose.

any help at all would be fab thanks in advance

Hi. I think its telling you to pace yourself a little more. Lower intensity for longer periods. Keep your heart rate at 70% for maximum fat burning.
