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 LaLanneIt's a bunch of bull! If God, or nature, or whatever you want to call it didn't want you to mix carbohydrates, starches and fats, you'd never have a grain, you'd never have a vegetable or a fruit, would you? What's in a grain? It's got carbohydrates, starches, fats, sugar. It's got everything in it. Why does nature do that? One guy says don't mix carbohydrates, and the other guy says don't mix protein with it; it's all a bunch of lard, something to sell a book. And the poor public is so confused, they don't know what to do.
Jack LaLanneWho puts the food in your mouth? Who goes to the bathroom for ya? You do. You came on this earth alone and you are going to leave alone. Think about it. If anything happens to Jack La Lanne good or bad, I made it happen. If anything happens to you good or bad, you made it happen - right?
