Everything You Ever Wanted to Know About Exercise


Q: Why do men lose weight faster than women?
Men naturally have a higher "VO2 max," which is the maximum amount of oxygen a person can use during exercise. And the more oxygen you use, the more calories you burn. Also, pound for pound, men have more lean muscle mass, which burns more calories at rest than fat tissue does.

Q: Should I work out every day?
A: It's okay to do cardiovascular exercise daily, but you shouldn't strength-train every day — your muscles need time to recover. In general, it's good to take one day off entirely each week: Remember, exercise is stressful on the body, plus you don't want to burn out mentally.

Q: How often do I need to buy new workout shoes?
The general rule is every 500 miles, but sneakers tend to last longer if you're using them on cardio and weight machines versus pounding the pavement with regular outdoor runs.

Q: How many calories should I expend each day to lose weight?
A: To lose 1 pound a week you need to expend an additional 500 calories a day, either through exercise or cutting calories from your diet. Don't try to lose more than 2 pounds a week — people who lose weight quickly tend to regain it quickly.

Q: If I have only 30 minutes, what's the best way to utilize that time to burn the most calories and fat?
A: Work out at the high end of your target heart rate zone doing anything that gets you up to that level, whether it's doing one cardiovascular activity or a combination of activities.
