Hi Everyone! I've been working out 5days a week since 9/11/11. A few weeks ago I bought a hr monitor by polar which I wear during each workout. Last week I did my workout B which consisted of total body weight training and low intensity cardio for about 30minutes. When I started wearing the watch I wanted to stay in zone 2 which is the fat burning zone (HR for zone 2 between 123 - 131). At the end, I would check my Polar HR monitor and it showd 530 K/Cal burned for 1 hr I exercised. Just to note -I alternate workout A and B every other day. M W F. Tues/Thur I do nothing but cardio. So today I did workout B, increased my weights. When I checked my HR monitor today, it only showed that I had burned 481 K/Cal.

Since I'm not burning as many calories as I have been the last few weeks, does that mean that my fat/cardo zones have changed and do I need to now keep my HR at a little higher level during cardio?

Frustrated :-( oh one more thing, I work out first thing in the mornings and all week this week my calories burned has not been what it used to be.

Thanks guys for any advise

    The harder you can go the more calories you burn. You're going to burn more calories working above the "zone" then you will in the "Zone" if you do it for the same amount of time.

    The balancing act is pacing the intensity with the duration. Better to go at, for example, 150 for an hour than at 180 for half an hour. If you can manage to do 180 for an hour, that's better than both.
