HEART rate *burning fat ?

[lil hulk]

how does everyone figure out what their heart rate should be to burn fat not muscle.

ive heard 220-age X 65% is that correct or not

[skribbble]

220-20x 65% = 130...looks good to me

Does it burn up muscle using higher heart rates? I usually run mine between 170 and 180 for 40 minutes

I am 6' 225 age 33.

yes ... I'm 33 also around 210-215 lbs .... I was going for an hour at 170 and getting thinner but thinner everwhere ... arms especially .... now i go between 130-135 and maintain

[..Fit4life..]

for fat burning anything between 65% and 75%
(220-AGE)0.7 = HR
