Which machine will give me more calories burnt for my time? Is there perhaps a website or calorie burner calculator that I could figure this out with?
Thanks!

As a physical therapist, I encourage you to do whatever exercise is FUN, and, of course, does not cause any pain. If you follow that rule, you'll stick with it longer in both short-term time and duration time and you'll be able to increase your intensity, therefore burning more calories.

HAVE FUN!!!

Try this Squeaky..it's an activity calorie calculator..

Flower, how accurate is that calculator? (I know every ones body is different, but on average is it pretty accurate?)

The best exercise is the one you will consistently perform for the rest of your life.
