Everything You Ever Wanted to Know About Exercise


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.
