Twelve to seventeen minutes is plenty on the treadmill--if it's done fast. That's all you need for cardiovascular benefit. You don't need to spend that extra time unless you are over weight and you need to burn off extra calories. Do it vigorously, like somebody is chasing you. You've got to do it hard. Otherwise, if you just take it easy and do it longer, you are spending all that time when you don't need it. Use that extra time with your weights instead.
Jack LaLanneI've never been satisfied with myself, ever. But I feel good about myself, because I'm truthful. I don't corrupt myself. I'm also a perfectionist. I'm very impatient. I've got energy and drive and I can't stand inefficiency in people. And I can't stand dumb people. Why surround yourself with people who are going to tie you down? I don't suffer fools.
Jack LaLannePeople don't realize how much of this stuff you get by the end of the day. High blood pressure is from all this high-fat eating. Do you know how many calories are in butter and cheese and ice cream? Would you get your dog up in the morning for a cup of coffee and a donut? Probably millions of Americans got up this morning with a cup of coffee, a cigarette and a donut. No wonder they are sick and fouled up.
