I agree with other posters. It's not so much if you feel tired after but how hard you're working during. Rate your exertion on a scale from 1-10. 1 being sitting still doing nothing. 10 being working as hard as you possibly can. You should be at about a 6-7. If you're under 55 (for male) or under 65 for female and in good health, you can even push it to a 9-10 for 30-60 seconds at a time to really optimize your fat burning results post-workout.

I didn't get healthy because I lost weight, I lost weight because I got healthy!
The TRUE key to weight loss success is educating yourself ABOUT YOURSELF! Don't let someone else do it for you because no one has all the answers! No one! Don't trust one book, one doctor, one nutritionist, etc.
