Walking and chewing gum at the same time...

Hi All,
Well, how about walking and talking on the cellphone at the same time?
Here's my question...what is the friggin' point of walking for exercise (which I feel, as you know, really isn't EXERCISE, unless you walk and get your heart rate up as high as you do in class) when all you're really doing is walking and talking on the cellphone?
Every single day I am driving around doing many errands, etc. for the Center and for my family. Daily, I see folks who are walking through my neighborhood and others just talking on the phone.
These people are overweight and 'think' they are exercising. The only wakeup call they're going to get is when they have that heart attack and they'll be all, "Hey, I exercise every day." Uh, no you do not. You walk around the block talking on the phone, which means you're not getting heart rate up if you can have a FULL BLOWN conversation while you're doing it. Is it better than sitting on your arse talking on the phone? Sure, but just barely.
Oh and that brings up another point...related to class.
If we are at the top of the aerobic curve and you are having a full blown convo with your neighbor then here's what happening in your body:
Nada
Nothing
You are NOT WORKING hard enough.
Oh and you're being rude to those around you.
And you're not burning fat.
Now, we're not talking about a quick WOO HOO or comment like "I hate this routine" or "I love this routine"...we're talking about a FULL BLOWN convo.
You are never going to get your heart rate up TOO high in class...our aerobic curve and the skill of our instructors make sure of that. So push yourself...focus on what you're doing and talk to your friends later. They'll still be there.
Oh and so will you because you worked hard, actually GOT fit and will be able to enjoy years and years of chatting with your friends, sitting on your arse and not feeling the least bit bad...you already GOT a real workout here!
