Bob says walking is a great exercise to get in shape for the summer. It's easy on your body, and you can do it anywhere, anytime, no matter who you are. When you set out, go for time (20 to 30 minutes to start; 45 minute to an hour for more advanced walkers), not distance. Make sure you're walking at a good clip. On a scale of 1 to 10, your walk should be 7—you can still talk but you don't want to have a long conversation. And don't forget to warm up and cool down!
Bob suggests increasing the amount of water you drink during the summer months. This is important both for staying hydrated during a workout and for staying fit. Bob says we often reach for food when our bodies really require more water. Water also has a "filling" effect, making us less prone to overeating.
Classic diets generally make us feel as though we are depriving ourselves, something we can't do for very long. And drastically decreasing the calories you eat slows your metabolism, causing you to lose energy and motivation, which will sabotage your efforts.
Instead, allow your body to increase your metabolism and adjust to your new cardiovascular exercise for one to two months. It's very important to exercise aerobically, then gradually change your eating habits—eliminate late-night eating, eat breakfast and reduce portion sizes. This will have a much greater impact and not cause your metabolism to shut down.
