I can't agree with you more. However, I think this shows the importance of going hard. When I am at the gym and I see these people leisure peddling a bike while reading a book or a magazine, I just don't get it, why bother at all? Peddling slowly for 40 minuets isn't going to do jack. If you go to the gym go all out, push yourself as hard as you can until you body fails. Then rest and push until it fails again. Work through the failure. If you aren't wobbling out of the gym then you failed.
